When clearing fault codes, it is essential to strictly follow the specific fault code clearing procedure designated for the particular vehicle model. Under no circumstances should the negative ground cable be disconnected directly to clear the fault code. 1. Meaning of P0251 fault code: The P0251 fault code, applicable to all automobile manufacturers, indicates a malfunction in the fuel metering control A (cam/rotor/injector) of the injection pump. 2. Possible causes: This may include issues with the Fuel Control Actuator (FCA), its circuitry, the injection pump, or the Electronic Control Module (ECU). The Fuel Control Actuator (FCA) is typically located on the rear side of the injection pump and functions as an electronically controlled solenoid valve. The ECU regulates the amount of fuel entering the injection pump by cyclically opening and closing the FCA.
