Q: What does code P2A1E mean?

Injection Pump Fuel Metering Control F (Cam/Rotor/Injector). P2A1E indicates that the engine control module has detected an out-of-range condition in the fuel metering control circuit for injection pump circuit F, which may involve the cam, rotor, or injector depending on the specific pump design. The computer monitors the electrical command and feedback signals for this circuit and sets the code when the measured current or voltage deviates from the expected value for a calibrated time.
