P2014 indicates that the powertrain control module (PCM) has detected an electrical fault in the intake manifold runner position sensor or its circuit on bank 1. This sensor monitors the position of the variable intake manifold runner flaps, which optimize airflow at different engine speeds.
The sensor itself may be internally open, shorted, or providing an erratic signal.
Open circuits, short to ground/power, or corroded pins in the sensor harness or connector.
Carbon buildup or mechanical wear can prevent the flaps from moving, causing the sensor to report an implausible position.
If the system uses vacuum actuation, a leak or failed actuator can prevent proper runner movement.
The PCM's sensor input circuit may be damaged, but this is uncommon and should only be considered after all other causes are ruled out.
No. PCM failure is a very rare cause of P2014. The code is almost always due to the sensor, wiring, or mechanical runner issues. Replace the PCM only after all other possibilities have been thoroughly eliminated.
Yes. Excessive carbon deposits on the intake manifold runner flaps can cause them to stick, preventing the sensor from reading the expected position and triggering the code.
Clearing the code only turns off the light temporarily. If the underlying fault (sensor, wiring, or mechanical) is not repaired, the code will return once the PCM runs its monitor.
Yes. P2014 is an emissions-related code and will cause a vehicle to fail an OBD-II readiness check or tailpipe emissions test in most jurisdictions.
