Table Of Contents

    Description of DTC code P025A Generic

    Modern vehicle fuel systems require high fuel pressures. The ECM (Engine Control Module) meets the needs of the fuel system through the Fuel Pump Module, which is responsible for regulating the fuel system pressures. The pump, on the other hand, has the function of delivering fuel to the engine.

    When the DTC P025A OBDII code is stored, it means that the ECM detected that the Fuel Pump Module control circuit is performing poorly due to an open circuit.
