P003A P003A OBD-II: Turbocharger/Supercharger Boost Control "A" Position Exceeded
What P003A means for you
The code indicates a moderate issue with turbocharger performance that can lead to reduced engine functionality.
Symptoms
- The engine may enter a limp mode, resulting in diminished performance.
- There may be insufficient boost from the turbocharger or supercharger.
Common causes
- The Turbocharger Vane Control Solenoid regulates the boost generated by the turbocharger.
- Each time the ignition is turned on, the powertrain control module (PCM) conducts a self-diagnostic check to ensure the Turbocharger Vane Control Solenoid and its associated sensors are functioning correctly.
- The PCM commands the solenoid to fully open and close. If it does not detect the expected movement of the solenoid, it concludes that there is either a calibration loss or another malfunction in the turbocharger system, triggering code P003A.
- A relearn procedure is necessary whenever the Turbocharger or related components are serviced or replaced.
