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. Here the signal wire to the throttle motor is connected to supply voltage, so it is short-circuited to the positive side.
Possible causes
- The signal wire is short-circuited to supply voltage
What you can do
- 1Check that the fuses are intact
- 2Read the code with the ignition on and see whether it is still active
- 3Look for wiring that has rubbed against something live, or that may be touching another wire
- 4With the ignition off, use a multimeter to check whether the signal wire has voltage to ground. It should not
- 5If you have a diagnostic tool, compare the throttle position in live data with the accelerator pedal position, and check that they match
- 6If the fault remains, have a workshop with diagnostic equipment check the throttle unit and the engine control module
Symptoms you may notice1
- The Check engine light comes on or behaves abnormally
