Start the engine

Ignition on
Read off the movement of the accelerator pedal by carefully depressing and releasing the accelerator pedal (AP).
Check that the value changes with accelerator pedal movement. The value must be between approximately 0.4 V when the accelerator pedal (AP) is unaffected and approximately 4 V when the accelerator pedal (AP) is fully depressed.

The fault is intermittent at the moment if the values are OK.
