Analog Signal Too High

Analog signal too high

Checking components and wiring
Check the signal cable between accelerator pedal (AP) position sensor terminal #5 and engine control module (ECM) terminal #B17 (#B27). Check for a short-circuit to supply voltage.
Remedy as necessary.

Hint: After carrying out the repair, check that the fault has been remedied.








- Ignition off
- Reinstall the connectors, components etc.
- Ignition on.
Activate the read off of the signals from the accelerator pedal (AP) position sensor.
Check that the value for both signals is approximately 8% when the accelerator pedal (AP) is unaffected and approximately 82% when the pedal is fully depressed.





Do the values correspond?
