DTC codes / P2Axx · Hybrid propulsion / P2A14
P2A14 indicates that the engine control module has detected an abnormally low fuel metering signal from the injection pump's control circuit, specifically for the 'C' circuit that may involve the cam, rotor, or injector. The computer compares the commanded fuel quantity with the actual metering feedback and sets this code when the signal falls below the expected threshold for a calibrated time.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
