repair, Wiring: Precautions for repairs), repair the wiring; otherwise replace the wiring.
Pedal sensor connected, vehicle ignition on and engine stopped:
– check the value of PR030:
0% no load,
100% full load,
138% full load after kickdown point on pedal.
– if the value is not correct, replace the pedal sensor.
