    What does this fault code mean?

    The ECM checks the circuits to the injectors and stores the code when the signal to the injector for cylinder 4 is too high. The code is general and does not say what type of fault it is. It applies to cylinder 4 only.

    Possible causes

    • Signal wire short-circuited to supply voltage
    • Damaged injector
    • Open circuit in the signal wire
    • Several damaged injectors
    • A fault inside the ECM itself

    What you can do

    1. 1Read and note the fault code, clear it and test drive to see whether it returns
    2. 2With the ignition off and the connector disconnected, use a multimeter to check that the cylinder 4 signal wire has no open circuit
    3. 3Use a multimeter to check that the cylinder 4 signal wire has no contact with supply voltage
    4. 4Check the connector to the cylinder 4 injector for contact resistance and oxidation
    5. 5Have a workshop with diagnostic equipment check the injectors for cylinder 4 and their control

    Symptoms you may notice5

    • The emissions warning lamp comes on
    • The engine does not run on all cylinders
    • Uneven idle
    • The Check engine light comes on or behaves abnormally
    • The car lacks power

    What the fault can affect2

    • The control module blocks lambda control
    • Injection for cylinder 4 stops

    General guidance for car owners. Diagnosis on the car can point to a different cause.
