What does this fault code mean?
The engine control module has received a message from the central electronic module (CEM) saying that the analog accelerator pedal signal is too low. The signal travels over the CAN network, so the fault lies in the CEM rather than the engine control module. The code cannot be cleared until the CEM fault has been remedied.
Possible causes
- Fault in the central electronic module (CEM), which must be traced first
What you can do
- 1Read the fault codes in the central electronic module (CEM) first, since this code comes from there
- 2Trace and fix the faults in the CEM, with help from a workshop if needed
- 3Then clear the code in the engine control module and road test to see whether it returns
- 4Check that the connector at the accelerator pedal sensor is fully engaged and free from oxidation
- 5If the fault returns, have a workshop with diagnostic equipment check the CEM and the accelerator pedal sensor wiring
Symptoms you may notice1
- Text message and warning symbol in the display
What the fault can affect1
- If the PWM signal from the accelerator pedal sensor works, it is used instead
General guidance for car owners. Diagnosis on the car can point to a different cause.
