PR030ACCELERATOR PEDAL POSITION
PARAMETER
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),
MR 370 (Scénic II), MR 385 (Modus), MR 392 (Clio III), MR 411 (New Twingo), MR 417 (Kangoo 2),
