PR095ANTI-PINKING CORRECTION
PARAMETER
DEFINITIONThis parameter indicates the anti-pinking correction in volts.
NOTESThere must be no present or stored faults.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III or
MODUS.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80˚C
The pinking sensor must not supply a zero signal, proving that it is recording the mechanical vibrations of the
engine.
Carry out these checks if PR095 is not between 0 V and 8 V.
Check the conformity of the fuel in the tank, apply test 1 Petrol conformity check.
Repair if necessary.
Check the condition and conformity of the spark plugs.
Repair if necessary.
Check the tightness of the pinking sensor (20 Nm).
Repair if necessary.
Check the condition of the pinking sensor connector (component code 146) and the engine management computer
connector (component code 120).
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Use the universal bornier to check the insulation and continuity of the following connections:
●3S between components 120 and pinking sensor shielding,
●3S between components 120 and 146,
●3DQ between components 120 and 146.
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.
If the fault is still present, replace the pinking sensor.
