ACCELERATOR PEDAL POSITION
PARAMETER
DEFINITIONThis parameter indicates the accelerator pedal position as a percentage.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
No faults should be present or stored.
Perform this fault finding procedure:
– after finding an inconsistency in the parameter,
– after a customer complaint (e.g. lack of power).
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
>80 °C.
If no pressure is being applied to the pedal PR030 = 0%.
In the event of a fault, refer to the interpretation of fault DF008 Pedal potentiometer circuit gang 1 or DF009
Pedal potentiometer circuit gang 2.
Sensor electrical conformity.
Check the continuity and absence of interference resistance of the following connections:
– connection code 3LR,
– connection code 3LS,
– connection code 3LT,
– connection code 3LU,
– connection code3LW,
– connection code 3LV.
Between components 120 and 921.
If any of the connections are faulty and there is a repair method (see Technical Note 6015A, Electrical wiring
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.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
