|P0251 DODGE code descriptionThe Fuel Control Actuator (FCA) is an electronically controlled solenoid valve. The Engine Control Module (ECM) controls the amount of fuel that enters the high-pressure pumping chambers by opening and closing the FCA based on a demanded fuel pressure. When the FCA is opened, the maximum amount of fuel is being supplied to the fuel injection pump. Any fuel that does not enter the injection pump is directed to the cascade overflow valve. The cascade overflow valve regulates how much excess fuel is used for the lubrication of the pump and how much is returned to the fuel tank through the drain manifold. An audible click from the FCA is normal when operating the key from the ON to the OFF position.
The Diagnostic Trouble Code (DTC) will set when the ECM detects a discrepancy between the PWM supplied to the Electronic Fuel Control Actuator and the PWM returned from the Electronic Fuel Control Actuator.
