Use the universal bornier to check the insulation and continuity of the following connections:
●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.
Check the conformity of the fuel in the tank, apply test 1 Petrol conformity check.
Check that the spark plugs are correct.
Repair if necessary.
AFTER REPAIRFollow the instructions to confirm repair:
–If the fault is present, continue to deal with the fault.
–If the fault is stored, ignore it.
Deal with any other faults.
Clear the stored faults.

IDLING SPEED TOO LOW
Check:
–engine oil level (too high, splashing),
–that the exhaust pipe is not blocked (catalytic converter damaged),
–the cleanliness and conformity of the air filter,
–that the air inlet circuit is not blocked,
–that the throttle valve assembly is not clogged,
–the condition and conformity of the spark plugs,
–the fuel circuit sealing,
–the fuel pressure and the flow (see MR 392 (Clio III), MR 385 (Modus), MR 411 (New Twingo), or MR 442
(E33), Mechanical, 13A, Fuel supply),
–the condition and cleanliness of the injectors,
–the cylinder compression's,
–the timing setting.
Repair or replace the faulty components, if necessary.
IDLING SPEED TOO HIGH
Check:
–engine oil level (too high, splashing),
–for the fittings in the oil vapour rebreathing system,
–the sealing between the throttle valve and inlet manifold,
–the manifold pressure sensor sealing,
–the fuel vapour absorber bleed, which must not be jammed open,
–the fuel vapour absorber bleed system sealing,
–the brake servo system sealing,
–the sealing between the inlet manifold and cylinder head,
–the oil vapour recovery circuit sealing between the inlet manifold and cylinder head,
–the fuel pressure and the flow (see MR 392 (Clio III), MR 385 (Modus), MR 411 (New Twingo), or MR 442
(E33), Mechanical, 13A, Fuel supply),
–the condition and cleanliness of the injectors,
–the cylinder compression's,
–the timing adjustment,
Repair or replace the faulty components, if necessary.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

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.

ALP2 The engine will not start
NOTESApply ALP2 after a complete check using the diagnostic tool.
If the starter motor does not operate, there may be a fault with the engine immobiliser. Check status ET341
Immobiliser code programmed, if YES apply the following procedure, if NO, run command SC017 Programming
injection immobiliser code, in the UCH in repair mode (see 17B, Petrol injection, Replacement of
components).
In the event of a fault, perform fault finding on the UCH (see 87B, Passenger compartment connection unit).
Check the condition of the battery.
Check the cleanliness, condition and tightness of the battery terminals.
Check that the battery is correctly earthed to the vehicle bodywork.
Check that the + battery leads are correctly connected.
Carry out fault finding on the charging circuit (see Technical Note 6014A, Checking the charging circuit).
Check that the starter motor is properly connected.
Check that the starter operates correctly.
Check the condition and conformity of the spark plugs.
Check the mounting, cleanliness and condition of the flywheel signal sensor.
Check the flywheel signal sensor air gap.
Check the condition of the flywheel.
Check that the air filter is not clogged.
Check that the air inlet circuit is not blocked.
Check that there is fuel in the tank (fuel sender fault).
Check that the tank vent is not blocked.
Check the conformity of the fuel in the tank, apply test 1 Petrol conformity check.
Check that there are no leaks in the fuel system, from the tank to the injectors.
Check that there are no kinked hoses (especially after a removal operation).
Check the fuel flow rate and pressure.
Check the sealing of the injectors, and that they are working properly.
Check that the exhaust system is not blocked and the catalytic converter not clogged.
Check the timing setting.
Check the cylinder compressions.
