Fault Family System: Powertrain (P-Codes) 20 SAE Codes

IMRC Position Sensor

Diagnostic & Technical Explanation

P2014 (Intake Manifold Runner Position Sensor/Switch Circuit Bank 1) is triggered by the dedicated Hall-effect or potentiometer sensor that reports actual runner-flap angle back to the ECM, separate from the actuator drive circuit that moves it. The module compares commanded position against this feedback and flags a fault when the signal is missing, sits outside its calibrated voltage window, or fails to track motion smoothly. Sensor element wear, a cracked housing that lets in oil vapor, and mounting hardware loose enough to let the sensor slip out of alignment are the usual root causes.

These 20 diagnostic trouble codes share one detection mechanism and one repair path, which is why MechanicDB groups them into a single authored fault family rather than repeating the same explanation 20 times.
