Was bedeutet der Fehlercode?

The engine control module (ECM) compares the PWM signal with the analogue signal from the accelerator pedal sensor, and the code is set when the difference between them becomes too great. The analogue signal goes via the central electronic module (CEM) over CAN, so troubleshooting starts there. The code is also set on a fault in throttle potentiometer 2.

Mögliche Ursachen

Fault in the central electronic module (CEM)
Contact resistance and oxidation in the terminals
Signal wire between the control module and pedal sensor is damaged
Short-circuit in the connections
Signal cables short-circuited to each other
Damaged throttle unit

Was Sie tun können

1Read the fault codes in the central electronic module (CEM) first, since the pedal signal passes through CEM
2Check that the fuses are intact; their locations are in the owner's manual or on the fuse box cover
3Check the connectors at the pedal sensor and the throttle unit for contact resistance and oxidation
4Use a multimeter to check that the signal wires are not short-circuited to each other or to ground
5With a diagnostic tool, compare the two pedal signals in live data while the pedal is pressed and released; they should follow each other
6After a repair, read the diagnostic status and check that the code does not return

Symptome, die Sie bemerken können4

Accelerator pedal ignored when braking
The malfunction indicator (Check engine) lamp lights up or behaves abnormally
The car has poor performance and lacks power
Yellow warning symbol and a message in the display

Was der Fehler beeinflussen kann3

The lowest pedal position value from the two inputs is used by the control module
The control module treats the pedal as released when the brake pedal is pressed at the same time
If both potentiometers 1 and 2 have faults, the throttle motor supply is switched off and the throttle returns to its spring-loaded position
