NOTESThere must be no present or stored faults.
Check the cleanliness and condition of the downstream oxygen sensor connections.
Repair if necessary.
Disconnect the battery and the injection computer.
Using the Universal bornier, check the insulation and continuity of the following connections:
Injection computer, connectorC, track A2 track C of the downstream oxygen sensor
Injection computer, connectorC, track B2 track D of the downstream oxygen sensor
Repair if necessary.
Check the tightness of the downstream oxygen sensor.
Repair if necessary.
If the vehicle is driven frequently in town, carry out the unclogging procedure (oxygen sensors and catalytic
converter clogging).

Replace the downstream oxygen sensor.
If the fault is still present, the catalytic converter is certainly damaged.
If the catalytic converter is defective, determine the cause of the destruction, otherwise the new catalytic
converter may be damaged in turn.
Remove the catalytic converter.
Various things may destroy a catalytic converter:
–deformation (impact),
–thermal shock (cold water splashed onto a hot catalytic converter can damage it),
–defective injector or ignition: the catalytic converter is damaged by contact with fuel (coil fault, coil control fault,
injector jammed open),
–injector leak,
–abnormal oil or coolant consumption (defective cylinder head gasket),
–use of a fuel additive or other equivalent product (obtain information from the customer because this type of
product can contaminate the catalytic converter and render it useless sooner or later).
Look up the service history of the vehicle or, if this is not possible, ask the customer if the vehicle has had injection
or ignition faults.
If the cause of the catalytic converter damage has been found and the fault has disappeared, replace the
catalytic converter.
AFTER REPAIRRepeat the conformity check from the start.

MANIFOLD PRESSURE
NOTESThere must be no present or stored faults.
Check the cleanliness and condition of the manifold pressure sensor and its 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 of the following connections:
Injection computer, connectorB, track H2 track C of the manifold pressure sensor
Injection computer, connectorB, track H3 track B of the manifold pressure sensor
Injection computer, connectorB, track H4 track A of the manifold pressure sensor
Repair if necessary.
If the fault is still present, replace the manifold pressure sensor.
If the fault is still present, carry out the following checks:
The inlet line must be perfectly sealed, from the throttle valve to the cylinder head.
Check:
– the condition of the air filter,
– that the air inlet circuit is not blocked,
– 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.
Repair if necessary.
AFTER REPAIRRepeat the conformity check from the start.

NOTESThere must be no present or stored faults.
Switch the ignition on and run command AC079 Actuator static test.
If the following actuators are not working, apply the interpretation of the associated fault:
– Fuel pump relay, apply the interpretation of DF085 Fuel pump relay circuit.
– The motorised throttle, apply the interpretation of DF079 Motorised throttle valve servo control.
– The electric coolant pump, apply the interpretation of DF570 Coolant pump relay.
–Upstream O
2 sensor heating, apply the interpretation of DF601 Upstream O2 sensor heating power circuit.

TEST 2 Camshaft dephaser solenoid valve
Special NoteTo apply this method, it is necessary to use the special tool Elé. 1793, available in the
Parts Department catalogue.
Vdiag 4C only
– Disconnect the solenoid valve connector.
– Measure the electrical resistance between the
terminals of the solenoid valve at 20°C.
Is the electrical resistance of the solenoid valve
between 6.7Ω and 7.7Ω?
YES
Use the tool Elé. 1793 in accordance with the
method below:
– connect the tool to the solenoid valve and to
the vehicle battery,
– start the engine and maintain idle speed,
– actuate the solenoid valve with the tool
(by pressing on the button).
Does the engine stall and/or is the idle speed
very unstable?
NO
– Switch off the engine.
– Use the tool Elé. 1793 to operate the solenoid
valve. Press several times successively to hear
the solenoid valve.
NO– The solenoid valve is faulty.
– Replace the solenoid valve with a new one.
YES– The pulley-dephaser and the solenoid valve
operate.
