P2014 Intake Manifold Runner Position Sensor / Switch Circuit (Bank 1)

P2014 Intake Manifold Runner Position Sensor / Switch Circuit (Bank 1) is a generic OBD-II diagnostic trouble code indicating that the Engine Control Module (ECM/PCM) has detected a fault in the Bank 1 intake manifold runner position sensor or switch circuit.

The intake manifold runner system controls the path of intake air entering the engine. Depending on engine speed, engine load, throttle position, and other operating conditions, the runner mechanism may change position to optimize airflow.

A position sensor or switch provides feedback to the ECM/PCM so the control module can determine the position or operating state of the intake manifold runner.

When the ECM/PCM detects a general problem with this sensor/switch circuit, it may store P2014 and illuminate the Check Engine Light.

In simple terms, P2014 means the ECM/PCM has detected a malfunction in the Bank 1 intake manifold runner position sensor/switch circuit.

Possible causes include:

• Faulty intake manifold runner position sensor

• Faulty position switch

• Damaged wiring

• Open circuit

• Short circuit

• Corroded electrical connector

• Loose or damaged terminals

• Poor sensor ground

• Incorrect reference voltage

• Faulty runner actuator

• Damaged actuator wiring

• Sticking runner mechanism

• Damaged runner linkage

• Vacuum-control problems on vacuum-operated systems

• Intake manifold mechanical damage

• ECM/PCM control or circuit problems

• ECM/PCM software issues

P2014 is a general circuit code, so the code alone does not identify exactly which component has failed.

---

What Does P2014 Mean?

The code description contains several important terms.

Intake Manifold Runner

The intake manifold runner is the passage through which air travels toward the engine cylinders.

Many modern engines use an intake manifold runner control system to change airflow characteristics according to engine operating conditions.

Depending on the manufacturer, the system may be called:

• Intake Manifold Runner Control (IMRC)

• Intake Manifold Runner System

• Intake Runner Control

• Variable Intake Manifold

• Intake Manifold Flap Control

• Intake Manifold Tuning system

The exact design varies between engines.

The system can be used to improve:

• Low-RPM torque

• High-RPM airflow

• Throttle response

• Fuel economy

• Combustion efficiency

• Emissions performance

---

Position Sensor / Switch

The position sensor or switch provides feedback about the runner mechanism.

Depending on the vehicle, it may be:

• A variable position sensor

• A potentiometer-type sensor

• A position switch

• An integrated actuator position sensor

The ECM/PCM uses this feedback to determine whether the runner is operating correctly.

---

Bank 1

Bank 1 refers to the cylinder bank containing cylinder number one.

On a typical V-type engine:

• Bank 1 = side containing cylinder number one

• Bank 2 = opposite side

Therefore:

P2014 = Bank 1

For comparison:

P2023 = Bank 2 intermittent

P2022 = Bank 2 high

P2021 = Bank 2 low

Inline engines generally have only one cylinder bank.

---

Circuit

The word “Circuit” is important because P2014 does not specifically identify a low or high signal.

Unlike:

• P2016 = Circuit Low

• P2017 = Circuit High

• P2018 = Circuit Intermittent

P2014 identifies a more general circuit malfunction.

The problem may be located in:

• Sensor

• Switch

• Power supply

• Reference circuit

• Ground

• Signal wire

• Connector

• Harness

• Actuator circuit

• ECM/PCM circuit

Therefore, the technician must test the complete circuit rather than assuming the sensor is defective.

---

P2014 Does Not Automatically Mean the Runner Is Stuck

P2014 should not automatically be interpreted as a mechanically stuck intake runner.

For example, the runner mechanism may move normally while the electrical connector has a poor connection.

In another case, the sensor may work correctly but its signal wire may be broken.

Another possibility is that the runner actuator itself has an electrical fault.

Therefore:

P2014 = general Bank 1 runner position sensor/switch circuit fault

It does not automatically mean:

P2014 = bad sensor

or:

P2014 = stuck runner

The actual cause must be determined through testing.

---

How Does the Intake Manifold Runner System Work?

The intake runner system changes the airflow path or effective intake geometry.

Depending on the engine, it can contain:

• Runner flaps

• Electric actuator

• Vacuum actuator

• Control solenoid

• Position sensor

• Position switch

• Mechanical linkage

A simplified operating sequence is:

ECM/PCM → Actuator → Runner mechanism → Position sensor/switch → Feedback → ECM/PCM

The ECM/PCM commands the runner to a particular position.

The actuator moves the runner.

The position sensor reports the position.

The ECM/PCM evaluates the feedback.

If the sensor/switch circuit malfunctions, P2014 can be stored.

---

Symptoms of P2014

Symptoms depend on the vehicle and the underlying fault.

Check Engine Light

The most common symptom is an illuminated Check Engine Light.

---

Reduced Engine Performance

If the runner system cannot be controlled or monitored correctly, intake airflow may not be optimized.

Possible symptoms include:

• Reduced engine power

• Sluggish acceleration

• Poor response

• Reduced performance at certain RPMs

---

Poor Low-RPM Torque

Some intake runner systems are designed to increase intake-air velocity at lower engine speeds.

A runner-control fault may reduce low-speed torque.

---

Poor High-RPM Performance

If the runner cannot move to its intended position at higher engine speeds, airflow can be affected.

---

Engine Hesitation

The vehicle may hesitate during acceleration or changes in engine load.

---

Poor Throttle Response

Throttle response may feel less consistent than normal.

---

Rough Idle

Some vehicles may develop:

• Rough idle

• Uneven engine operation

• Unstable idle speed

However, this symptom is not present on every vehicle with P2014.

---

Reduced Fuel Economy

Incorrect intake-air control can affect combustion efficiency and fuel consumption.

---

Increased Emissions

Improper intake airflow can affect combustion and emissions performance.

---

No Noticeable Performance Symptoms

Some vehicles may continue to drive normally apart from the Check Engine Light.

The ECM/PCM may use a default runner position when the feedback circuit cannot be trusted.

---

Common Causes of P2014

Faulty Intake Manifold Runner Position Sensor

A defective sensor can cause the ECM/PCM to detect a circuit malfunction.

Possible failures include:

• Internal electrical failure

• Incorrect resistance

• Damaged sensing element

• Internal wear

• Shorts

• Damaged connectors

• Corrosion

• Heat damage

---

Sticking Runner Flaps

The runner mechanism may become difficult to move because of:

• Carbon buildup

• Dirt

• Corrosion

• Worn bushings

• Damaged shafts

• Mechanical obstruction

A mechanically restricted runner can place abnormal demands on the actuator.

---

Carbon Buildup

Carbon deposits can interfere with runner movement and may eventually prevent the mechanism from reaching the required positions.

---

Damaged Runner Linkage

The linkage between the actuator and runner may be:

• Broken

• Disconnected

• Bent

• Loose

• Excessively worn

---

Vacuum-System Problems

Some intake runner systems use vacuum actuators.

Possible causes include:

• Cracked vacuum hose

• Disconnected hose

• Vacuum leak

• Weak vacuum supply

• Damaged actuator diaphragm

---

Faulty Vacuum-Control Solenoid

A failed control solenoid can prevent the runner actuator from receiving the required vacuum.

---

Intake Manifold Mechanical Damage

The internal runner mechanism can be damaged.

Possible problems include:

• Broken flap

• Damaged shaft

• Worn bushings

• Internal obstruction

• Broken internal components

---

Incorrect Sensor Installation

A recently replaced sensor may be:

• Misaligned

• Improperly mounted

• Incorrectly adjusted

• Incorrectly connected

---

Incorrect Replacement Sensor

A sensor may physically fit but still have incorrect electrical characteristics for the vehicle.

---

ECM/PCM Software Problem

In some applications, a calibration issue may cause incorrect monitoring of the runner position circuit.

A manufacturer software update may address a known issue.

---

ECM/PCM Circuit Fault

A problem inside the ECM/PCM input or control circuit is possible but uncommon.

It should generally be investigated only after external components and wiring have been verified.

---

Because P2014 is a generic OBD-II code, the exact diagnostic procedure and electrical specifications can vary between manufacturers.

---

How Is P2014 Diagnosed?

P2014 should be diagnosed as a complete circuit and runner-system problem.

The technician should determine whether the fault is caused by the sensor, switch, wiring, connector, actuator, runner mechanism, vacuum system, or ECM/PCM.

---

Step 1: Scan for Additional Trouble Codes

Use a suitable diagnostic scan tool to retrieve:

• Stored codes

• Pending codes

• History codes

• Freeze-frame data

Look for related codes involving:

• Intake manifold runner control

• Runner position

• Runner actuator

• Sensor reference voltage

• Sensor ground

• Vacuum control

• Engine performance

• Misfires

Additional codes can provide important clues.

---

Step 2: Review Freeze-Frame Data

Review the operating conditions under which P2014 was stored.

Depending on the scan tool, check:

• Engine RPM

• Engine load

• Vehicle speed

• Throttle position

• Engine coolant temperature

• Intake air temperature

• Battery voltage

• Runner commanded position

• Runner actual position

This can help determine when the fault occurs.

---

Step 3: Inspect the Position Sensor or Switch

Inspect the Bank 1 sensor/switch for:

• Physical damage

• Loose mounting

• Contamination

• Incorrect installation

• Misalignment

---

Step 4: Inspect the Connector

Check the electrical connector for:

• Corrosion

• Moisture

• Bent pins

• Loose terminals

• Poor terminal tension

• Damaged seals

• Broken locking mechanism

---

Step 5: Check Power and Reference Voltage

Using the vehicle-specific wiring diagram, identify the sensor's:

• Power supply

• Reference voltage

• Ground

• Signal circuit

Verify each circuit according to the manufacturer's specifications.

Do not assume the connector pinout or voltage specification.

---

Step 6: Check Sensor Ground

Verify the sensor ground circuit.

A poor ground can create incorrect or unstable sensor operation.

---

Step 7: Check Sensor Signal

Monitor the position sensor signal while the runner mechanism operates.

Depending on the sensor design, the signal should change appropriately as the runner moves.

Look for:

• No signal

• Incorrect signal

• Sudden signal jumps

• Dropouts

• Dead spots

• Implausible position values

---

Step 8: Check Wiring Continuity

Test the wiring between the sensor/switch and ECM/PCM.

Check for:

• Open circuit

• Excessive resistance

• Short to ground

• Short to voltage

• Short between circuits

---

Step 9: Perform a Wiggle Test

Monitor the circuit while carefully moving the wiring harness and connector.

If the signal changes unexpectedly, investigate the harness and connector for an intermittent connection.

---

Step 10: Inspect the Actuator Circuit

If the runner system uses an electric actuator, check:

• Actuator power

• Actuator ground

• Control circuit

• Connector

• Wiring

• Motor operation

---

Step 11: Monitor Commanded and Actual Runner Position

If live data is available, compare:

Commanded runner position vs. actual runner position

A large or persistent mismatch can indicate:

• Actuator problem

• Mechanical binding

• Linkage problem

• Position sensor problem

---

Step 12: Test the Runner Actuator

Use the diagnostic equipment to command the actuator if supported.

Verify that it:

• Moves smoothly

• Reaches commanded positions

• Does not stick

• Does not stop prematurely

• Produces consistent position feedback

---

Step 13: Inspect the Runner Linkage

Check for:

• Broken linkage

• Disconnected linkage

• Excessive play

• Worn joints

• Bent components

---

Step 14: Check for Mechanical Binding

Verify that the runner mechanism can move freely through its intended range.

Inspect for:

• Carbon buildup

• Dirt

• Corrosion

• Worn bushings

• Damaged flaps

• Internal manifold damage

---

Step 15: Check Vacuum Operation

For vacuum-operated systems, inspect:

• Vacuum supply

• Vacuum hoses

• Control solenoid

• Actuator diaphragm

• Vacuum reservoir where applicable

---

Step 16: Compare Bank 1 and Bank 2

If the engine uses equivalent runner systems on both banks, compare:

• Sensor signals

• Reference voltage

• Ground

• Actuator operation

• Runner movement

• Commanded position

• Actual position

A normal Bank 2 system can provide a useful reference.

However, direct comparison should only be made when the two systems are equivalent.

---

Step 17: Check Manufacturer Technical Information

Check for:

• Technical Service Bulletins

• Known runner-system faults

• Wiring harness problems

• Connector issues

• Updated sensors

• Updated actuators

• Software updates

• Calibration procedures

Manufacturer-specific information is particularly important because the exact circuit design and diagnostic thresholds vary.

---

Step 18: Perform Required Calibration or Relearn

Some vehicles require runner position calibration or relearn after replacing:

• Position sensor

• Runner actuator

• Intake manifold

• Runner mechanism

Follow the manufacturer's procedure.

---

Step 19: Verify ECM/PCM Operation

If the sensor, switch, wiring, connector, actuator, vacuum system, and mechanical runner mechanism all test correctly but P2014 continues to return, further ECM/PCM testing may be required.

---

How to Fix P2014

The correct repair depends on the confirmed cause.

Replace the Faulty Position Sensor or Switch

If testing confirms that the sensor or switch is defective, replace the correct vehicle-specific component.

---

Repair Damaged Wiring

Repair or replace wiring affected by:

• Heat

• Chafing

• Vibration

• Oil

• Moisture

• Previous repairs

Secure the harness correctly after repair.

---

Repair or Replace the Connector

If the connector has:

• Corroded terminals

• Loose pins

• Bent terminals

• Poor terminal tension

• Damaged seals

repair or replace it as required.

---

Repair Power, Reference, or Ground Circuits

If the sensor does not receive the required electrical supply, reference voltage, or ground, repair the affected circuit.

---

Repair the Runner Actuator

If the actuator has an electrical or mechanical fault, repair or replace it.

---

Repair the Runner Linkage

Replace broken, disconnected, bent, or excessively worn linkage components.

---

Clean or Repair the Runner Mechanism

If carbon buildup or contamination causes the runner to stick, clean or repair the mechanism according to the manufacturer's procedure.

---

Repair Vacuum-System Problems

For vacuum-operated systems, repair:

• Cracked hoses

• Disconnected hoses

• Vacuum leaks

• Faulty control solenoids

• Damaged actuator diaphragms

---

Replace the Intake Manifold

If the internal runner mechanism is damaged and cannot be repaired separately, the intake manifold may require replacement.

---

Perform Calibration or Relearn

If required by the manufacturer, perform the runner position calibration or relearn after the relevant component has been replaced.

---

Update ECM/PCM Software

If a manufacturer software update addresses a runner-system monitoring problem, update the ECM/PCM according to the manufacturer's procedure.

---

Repair or Replace the ECM/PCM

If all external components and circuits are confirmed to be correct but P2014 continues to return, further module testing may be necessary.

ECM/PCM replacement should be considered only after the external circuit and components have been verified.

---

Clear the Code and Verify the Repair

After completing the repair:

1. Clear P2014.

2. Monitor Bank 1 runner position data.

3. Check sensor/switch operation.

4. Verify power and reference voltage.

5. Verify sensor ground.

6. Check the signal circuit.

7. Inspect the connector.

8. Test wiring continuity and resistance.

9. Perform a wiggle test.

10. Test the runner actuator.

11. Inspect the runner linkage.

12. Check for mechanical binding.

13. Check the vacuum system where applicable.

14. Perform the required calibration or relearn.

15. Complete the appropriate drive cycle.

16. Confirm that P2014 does not return.

The vehicle should ideally be tested under the operating conditions in which the original fault occurred.

---

What Happens If P2014 Is Ignored?

P2014 usually does not mean that the engine will immediately fail.

However, the ECM/PCM may not be able to correctly monitor or control the Bank 1 intake manifold runner system.

Possible consequences include:

• Reduced engine performance

• Poor throttle response

• Reduced low-RPM torque

• Poor high-RPM performance

• Reduced fuel economy

• Increased emissions

• Engine hesitation

• Rough engine operation

• Continued Check Engine Light

• Additional runner-system faults

The consequences depend on whether the underlying fault is electrical, mechanical, or actuator-related.

---

Can You Drive With P2014?

In many cases, a vehicle with P2014 can still be driven if the engine starts and operates normally.

P2014 generally does not indicate an immediate catastrophic engine failure.

However, the fault should not be ignored.

Driving should be treated more cautiously if the vehicle also has:

• Severe hesitation

• Significant power loss

• Stalling

• Engine misfires

• Rough running

• Multiple engine-control codes

• Poor throttle response

If the Check Engine Light is flashing or the engine is actively misfiring, the vehicle should be inspected promptly.

---

Is P2014 a Serious Code?

P2014 is generally considered a low-to-moderate severity diagnostic trouble code.

The actual severity depends on the underlying cause.

A simple connector or wiring problem may have relatively minor symptoms.

A failed actuator, damaged linkage, or mechanically restricted runner can have a greater effect on engine performance.

Ignoring P2014 can contribute to:

• Reduced engine performance

• Reduced fuel economy

• Increased emissions

• Poor intake-air management

• Continued Check Engine Light

• Additional runner-system problems

---

P2014 vs. P2015

P2014 and P2015 concern the same general Bank 1 intake manifold runner position system, but they identify different fault conditions.

Code	General Meaning
P2014	Intake Manifold Runner Position Sensor / Switch Circuit (Bank 1)
P2015	Intake Manifold Runner Position Sensor / Switch Circuit Range / Performance (Bank 1)

The distinction is:

P2014 = general circuit malfunction

P2015 = range/performance problem

P2014 points more broadly toward the electrical circuit, sensor/switch, connector, wiring, actuator circuit, or related system.

P2015 indicates that the sensor feedback or runner operation is outside the expected range or performance parameters.

A P2015 fault can therefore involve a mechanical runner problem even when the electrical circuit itself is functioning correctly.

---

P2014 vs. P2016

Code	General Meaning
P2014	Intake Manifold Runner Position Sensor / Switch Circuit (Bank 1)
P2016	Intake Manifold Runner Position Sensor / Switch Circuit Low (Bank 1)

The key difference is:

P2014 = general circuit fault

P2016 = low circuit signal

P2016 specifically identifies a signal below the expected threshold.

P2014 does not specify whether the signal is low or high.

---

P2014 vs. P2017

Code	General Meaning
P2014	Intake Manifold Runner Position Sensor / Switch Circuit (Bank 1)
P2017	Intake Manifold Runner Position Sensor / Switch Circuit High (Bank 1)

The difference is:

P2014 = general circuit malfunction

P2017 = high circuit signal

P2017 specifically points toward a signal above the expected threshold.

---

P2014 vs. P2018

Code	General Meaning
P2014	Intake Manifold Runner Position Sensor / Switch Circuit (Bank 1)
P2018	Intake Manifold Runner Position Sensor / Switch Circuit Intermittent (Bank 1)

The distinction is:

P2014 = general circuit malfunction

P2018 = intermittent circuit fault

P2018 places particular emphasis on faults that appear and disappear because of:

• Vibration

• Harness movement

• Loose connectors

• Corrosion

• Heat

• Internal sensor problems

---

P2014 vs. P2019

Code	General Meaning
P2014	Intake Manifold Runner Position Sensor / Switch Circuit (Bank 1)
P2019	Intake Manifold Runner Position Sensor / Switch Circuit Malfunction (Bank 2)

The primary difference is the engine bank:

P2014 = Bank 1

P2019 = Bank 2

Both are general circuit-related codes, but they concern opposite cylinder banks.

---

P2014 vs. P2020

Code	General Meaning
P2014	Intake Manifold Runner Position Sensor / Switch Circuit (Bank 1)
P2020	Intake Manifold Runner Position Sensor / Switch Circuit Range / Performance (Bank 2)

The differences are:

P2014 = Bank 1 + general circuit fault

P2020 = Bank 2 + range/performance

---

P2014 vs. P2021

Code	General Meaning
P2014	Intake Manifold Runner Position Sensor / Switch Circuit (Bank 1)
P2021	Intake Manifold Runner Position Sensor / Switch Circuit Low (Bank 2)

P2014 identifies a general Bank 1 circuit fault.

P2021 specifically identifies a low Bank 2 signal.

---

P2014 vs. P2022

Code	General Meaning
P2014	Intake Manifold Runner Position Sensor / Switch Circuit (Bank 1)
P2022	Intake Manifold Runner Position Sensor / Switch Circuit High (Bank 2)

P2014 = Bank 1 general circuit fault.

P2022 = Bank 2 high signal.

---

P2014 vs. P2023

Code	General Meaning
P2014	Intake Manifold Runner Position Sensor / Switch Circuit (Bank 1)
P2023	Intake Manifold Runner Position Sensor / Switch Circuit Intermittent (Bank 2)

P2014 identifies a general Bank 1 circuit malfunction.

P2023 identifies an intermittent Bank 2 circuit problem.

---

P2014 vs. P2075

P2075 concerns the Intake Manifold Tuning (IMT) Valve Position Sensor / Switch Circuit Malfunction (Bank 1).

Code	General Meaning
P2014	Intake Manifold Runner Position Sensor / Switch Circuit (Bank 1)
P2075	Intake Manifold Tuning (IMT) Valve Position Sensor / Switch Circuit Malfunction (Bank 1)

The descriptions are similar, but they should not automatically be treated as identical codes for the same physical component.

Different manufacturers can use different terminology and different intake-air control architectures.

---

P2014 vs. P2076

P2076 concerns the Intake Manifold Tuning (IMT) Valve Position Sensor/Switch Circuit Range/Performance (Bank 1).

Code	General Meaning
P2014	Intake Manifold Runner Position Sensor / Switch Circuit (Bank 1)
P2076	Intake Manifold Tuning (IMT) Valve Position Sensor / Switch Circuit Range / Performance (Bank 1)

Although both descriptions concern Bank 1 intake-air position feedback, they do not necessarily identify the same physical mechanism.

The exact component should be confirmed using the vehicle's wiring diagram and service information.

---

How to Prevent P2014

Not every runner-system fault can be prevented, but proper maintenance can reduce the likelihood of problems.

Recommended practices include:

• Inspect runner-system wiring during routine service.

• Keep wiring away from excessive engine heat.

• Secure wiring harnesses against vibration.

• Check electrical connectors for corrosion.

• Make sure terminals maintain proper contact tension.

• Prevent moisture from entering electrical connectors.

• Repair damaged wiring promptly.

• Inspect vacuum hoses on vacuum-operated runner systems.

• Address excessive intake carbon buildup when appropriate.

• Repair loose or damaged runner linkage.

• Use the correct replacement sensor or switch.

• Follow required calibration procedures after component replacement.

• Make sure connectors are fully seated after service.

• Avoid damaging wiring during intake manifold repairs.

• Follow manufacturer maintenance recommendations.

• Do not ignore Check Engine Light warnings.

Final Thoughts

P2014 Intake Manifold Runner Position Sensor / Switch Circuit (Bank 1) indicates that the ECM/PCM has detected a general malfunction in the Bank 1 intake manifold runner position sensor or switch circuit.

Unlike P2016 and P2017, P2014 does not specifically identify a low or high signal.

Unlike P2015, it does not specifically identify a range/performance mismatch.

Unlike P2018, it does not specifically identify an intermittent circuit condition.

This makes P2014 a broader circuit fault that can involve:

• Position sensor

• Position switch

• Wiring

• Connector

• Power supply

• Reference voltage

• Ground circuit

• Signal circuit

• Runner actuator

• Actuator wiring

• Runner linkage

• Vacuum system

• Mechanical runner mechanism

• Intake manifold

• ECM/PCM

The most effective diagnostic approach is therefore to inspect and test the complete runner position circuit and the mechanical runner system rather than replacing the sensor immediately.

Start by scanning for additional trouble codes and reviewing freeze-frame data.

Then inspect the sensor/switch, connector, wiring, power supply, reference voltage, ground, and signal circuit.

If the electrical circuit is functioning correctly, investigate the runner actuator, linkage, vacuum system where applicable, and mechanical runner mechanism.

Live data is particularly useful when it allows the technician to compare the commanded runner position with the actual position.

If the runner fails to reach the commanded position, the actuator or mechanical mechanism may be responsible.

If the runner moves correctly but the ECM/PCM does not receive the expected feedback, the sensor, switch, wiring, connector, or related circuit should be investigated.

The sensor should not automatically be replaced simply because P2014 is stored.

P2014 is generally a low-to-moderate severity fault, and many vehicles can still be driven if they operate normally. However, the underlying problem should be repaired because incorrect intake runner operation can affect engine performance, throttle response, fuel economy, and emissions.

After the confirmed fault has been repaired, clear the code and perform any required calibration or relearn procedure.

The vehicle should then be tested under the operating conditions that originally triggered the fault.

The Bank 1 runner system should operate correctly, the position feedback should be valid, and P2014 should not return.
