Was bedeutet der Fehlercode?
The code is stored when the engine control module detects an incorrect signal on circuit 2, or when circuits 1 and 2 do not match. It is tested while driving, and the fault may be caused by a damaged accelerator pedal position sensor.
Mögliche Ursachen
- Damaged accelerator pedal position sensor
Was Sie tun können
- 1Start by checking the connectors at the accelerator pedal for play and corrosion, and the wiring for chafing
- 2Have a diagnostic tool? Follow the pedal movement in live data while you slowly press and release the pedal, and check that circuit 1 and circuit 2 follow each other
- 3Use a multimeter to check that the circuit 2 signal wire is not broken or short-circuited to ground or voltage
- 4If the wiring is sound but the fault remains, have a workshop check the accelerator pedal position sensor
Symptome, die Sie bemerken können1
- No noticeable symptoms for the driver
Allgemeine Hinweise für Fahrzeughalter. Die Diagnose am Fahrzeug kann eine andere Ursache zeigen.
