Details of the p003c OBD Code
Fault code P003C relates to the turbocharger boost control module performance being out of range.
OBD code P003C means that the turbocharger or supercharger bypass valve control circuit is low.
This code is triggered by the Engine Control Module (ECM) when it detects a low voltage condition in the control circuit of the turbocharger or supercharger bypass valve.
The ECM monitors this circuit to ensure proper operation of the turbocharger or supercharger system, which helps regulate engine performance and emissions.
