What does this fault code mean?
The engine control module has found an internal checksum error in the control of the throttle motor. It is classed as an internal system fault and is checked with the ignition on. The code shows that something in the control does not match, but it does not point to one particular part.
Possible causes
- Contact resistance or oxidation in the connectors
What you can do
- 1Check that the fuses are intact
- 2Read the code with the ignition on and see whether it is still active
- 3Check the connectors at the throttle unit and at the engine control module for loose connections and oxidation
- 4After any work, read the code again to confirm that it has cleared
- 5If the fault remains, have a workshop with diagnostic equipment check the throttle unit and the engine control module
Symptoms you may notice1
- No noticeable symptoms for the driver
