What does this fault code mean?
The ECM controls injection timing and duration through the injectors and stores the code when the signal to the injector for cylinder 6 is too low. The code is general and does not say what type of fault it is. It applies to cylinder 6 only.
Possible causes
- Contact resistance and oxidation in the connections
- Signal wire short-circuited to ground
- Damaged injector
What you can do
- 1Read and note the fault code, clear it and test drive to see whether it returns
- 2Check the connector to the cylinder 6 injector for contact resistance and oxidation
- 3With the ignition off and the connector disconnected, use a multimeter to check that the cylinder 6 signal wire is not short-circuited to ground
- 4Have a workshop with diagnostic equipment check the injector for cylinder 6 and its control
Symptoms you may notice2
- The emissions warning lamp comes on
- The engine does not run on all cylinders
What the fault can affect1
- The control module blocks lambda control
