  • P0252 Fuel Valve Signal Missing

       (0 reviews)



    Monitor & Set Conditions

    Fuel injection pump fuel valve circuit is monitored after current feedback monitoring is complete and average engine speed is greater than 700 RPM. DTC may be stored when Engine Control Module (ECM) does not receive a signal from the solenoid valve to indicate valve movement.

    Possible Causes

    Fuel Injection Pump


    Turn ignition on. Using DRBIII(R) scan tool, erase any ECM DTCs. Test drive vehicle. Using scan tool, recheck for ECM DTCs. If DTC P0252 resets, replace fuel injection pump. See appropriate REMOVAL, OVERHAUL & INSTALLATION article. If DTC P0252 does not reset, test is complete.
