What does this fault code mean?
The engine control module drives the throttle motor through internal power stages and has found a fault in that control. The signal to the throttle unit reads too low because the signal wire has contact with ground, meaning the vehicle body.
Possible causes
- The signal wire is short-circuited to ground
What you can do
- 1Check that the fuses are intact
- 2Read the code with the ignition on and see whether it is still present after a test drive
- 3Look for chafed wiring to the throttle unit, especially where it may have rubbed against the body
- 4With the ignition off, use a multimeter to confirm the signal wire has no contact with ground
- 5Check that the connectors at the throttle unit and the engine control module are secure and free from corrosion
- 6If the code returns, 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
