DTC codes / P2Axx · Hybrid propulsion / P2A19
P2A19 indicates that the engine control module has detected an abnormally high signal from the fuel metering control circuit for injection pump circuit D, which is associated with the cam, rotor, or injector. The computer compares the commanded fuel quantity to the actual feedback from the pump's metering valve or actuator and sets this code when the circuit voltage or current exceeds the expected range.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
