DTC codes / Volkswagen codes / P1545
P1545 on Volkswagen vehicles indicates that the engine control module (ECM) has detected a malfunction in the throttle position control system, typically involving a discrepancy between the commanded and actual throttle valve positions. The ECM monitors the throttle actuator and position sensors and sets this code when the throttle plate fails to reach the target position within the expected time or when the sensor signals are implausible.
Guidance is general and written for Volkswagen vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
