DEFINITIONThis parameter indicates the accelerator pedal position as a percentage.
NOTESThere must be no present or stored faults.
Perform this fault finding procedure:
–after finding an inconsistency in the parameter,
–after a customer complaint (e.g. lack of power).
See the Wiring diagrams Technical Note for the vehicle.
Conformity check: 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 code 3LW,
●connection code 3LV,
●between components 120 and 921.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Pedal sensor connected, vehicle with 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 accelerator pedal sensor, component code 921 (see MR 364 (Mégane II),
