What does this fault code mean?
The signal wire to the throttle motor has contact with supply voltage, and the engine control module has registered this as an electrical fault in the control. The code therefore belongs to the electrical faults in the throttle unit control.
Possible causes
- The signal wire is short-circuited to supply voltage
What you can do
- 1Check that the fuses are intact
- 2Read the code, note it down, clear it and test drive to see whether it comes back
- 3Look for broken wires and pinched wiring to the throttle unit, especially where they run close to other live circuits
- 4With the ignition off, use a multimeter to confirm the signal wire has no voltage
- 5If you have a diagnostic tool, read the throttle position in live data with the engine idling and check that the value is steady
- 6If the code comes back, 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
