- Wiring shorted to ground or open.
- Missing or low 5 V reference voltage.
- Faulty position sensor.
- Faulty engine control module, less commonly.
Diagnosis and repair
- Check the factory information to identify which sensor track "G" refers to.
- Inspect the relevant connector and wiring.
- Measure the 5 V reference, ground and signal with a multimeter.
- Compare the signal with the other tracks in live data.
- Replace the sensor or pedal or throttle assembly, then clear the code and road test.
