ANTI-PINKING CORRECTION
NOTESThere must be no present or stored faults.
The pinking sensor must not supply a zero signal, proving that it is recording the mechanical vibrations
of the engine.
Check that there is the correct fuel in the fuel tank.
Repair if necessary.
Check the condition and conformity of the spark plugs.
Repair if necessary.
Check the tightness of the pinking sensor.
Repair if necessary.
Check the cleanliness and the condition of the pinking sensor connections.
Repair if necessary.
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the connections.
Using the universal bornier, check the insulation and continuity on the following connections:
Injection computer, connectorB, track B3 track 2 of the pinking sensor
Injection computer, connectorB, track B4 track 2 of the pinking sensor
Injection computer, connectorB, track B2Pinking sensor shielding
Repair if necessary.
If the fault is still present, replace the pinking sensor.
AFTER REPAIRRepeat the conformity check from the start.

UPSTREAM OXYGEN SENSOR VOLTAGE
NOTESThere must be no present or stored faults.
Check the cleanliness and condition of the upstream oxygen sensor connections.
Repair if necessary.
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the connections.
Using the universal bornier, check the insulation and continuity on the following connections:
Injection computer connectorC, track C1 track D of the upstream oxygen sensor
Injection computer, connectorC, track B1 track C of the upstream oxygen sensor
Repair if necessary.
Check that the upstream oxygen sensor is secure.
Repair if necessary.
If the vehicle is driven frequently in town, carry out a decoking procedure.
Check that there are no leaks in the exhaust system, from the manifold to the catalytic converter.
Repair if necessary.
If the fault is still present, replace the upstream oxygen sensor.
If the fault has still not been cured, continue with the checks.
Check:
– the condition of the air filter,
– that the air inlet circuit is not blocked,
– the condition and conformity of the spark plugs,
– that the catalytic converter is not clogged,
– 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 cylinder head oil vapour recovery system sealing,
– the sealing between the inlet manifold and cylinder head,
– the exhaust pipe sealing between the cylinder head and catalytic converter.
– the fuel flow rate and pressure.
