What does this fault code mean?
The engine control module (ECM) drives the throttle unit with a PWM signal. If it registers that the throttle has jammed while the signal is being driven, the code is set. The cause can be that the throttle sticks or has jammed, or that the throttle unit is damaged.
Possible causes
- The throttle in the throttle unit sticks or has jammed
- Damaged throttle unit
What you can do
- 1Check the connector at the throttle unit: it should be firmly seated and free of play, contact resistance and oxidation
- 2Check that the throttle is not blocked and has not stuck
- 3If you have a diagnostic tool: activate the throttle unit and listen for a ticking sound. It should be active for a while and then switch off automatically
- 4Remedy any faults, erase the fault code and test drive to see whether it returns. If it does, the throttle unit is probably damaged and should be replaced by a workshop
Symptoms you may notice1
- The car's performance is worse than normal
