DTC codes / P2Axx · Hybrid propulsion / P2A15
P2A15 indicates that the engine control module has detected an abnormally high signal from the fuel metering control circuit 'C' associated with the injection pump, cam, rotor, or injector. This circuit is responsible for precisely regulating fuel delivery, and a high signal means the commanded current or voltage is exceeding the expected range, which can disrupt injection timing and quantity.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
