P2294 - FUEL PRESSURE REGULATOR 2 CONTROL CIRCUIT / OPEN

Table Of Contents

    Description of DTC code P2294 Generic

    The fuel pressure regulator achieves constant fuel pressure in order to achieve proper operation of the fuel system. To achieve this, it allows an excessive amount of fuel to be expelled into the tank.

    The PCM (Powertrain Control Module) stores the P2294 OBDII fault code after finding a fuel pressure regulator circuit malfunction. Specifically, the code shows that the circuit is open.

    Symptoms of fault code P2294 Generic

    • Check Engine lamp illuminates.
    • Poor acceleration.
    • Reduced fuel efficiency.
    • Other fuel system-related diagnostic codes are set.

    Causes of OBD2 P2294 Generic

    The factors for which the DTC P2294 OBD2 is set are:

    • Fuel output power coming from the pump may not be sufficient.
    • There may be blockages in the fuel filter.
    • The fuel lines may have been damaged.
    • The fuel pressure regulator may be defective.
    • The FRP (Fuel Rail Pressure) sensor may be damaged.

    Possible solutions of the DTC code P2294 Generic

    The steps to follow to correct the P2294 OBDII error code are:

    • Inspect the fuel filter for blocking elements. Make the necessary corrections.
    • Verify the excellent condition of the cables and connectors of the circuit. It is also necessary to check that the ground signal is correct. Repair it as required.
    • Check fuel lines for damage causing supply instability. Correct as necessary.
    • Check regularly for leaks. Make repairs as required.
    • Use a pressure gauge to check the actual fuel pressure. Compare the result you get with the one specified by the manufacturer. If the pressure is out of range, maybe the FRP Sensor is not sending a correct reading to the PCM. If so, proceed to check the sensor connections. Similarly, check the resistance and reference voltage. If the values obtained are not within specifications, replace the sensor.
