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,

DOWNSTREAM OXYGEN SENSOR VOLTAGE
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 on the following connections:
Injection computer, connectorC, track A2 track D of the downstream oxygen sensor
Injection computer, connectorC, track B2 track C of the downstream oxygen sensor
Repair if necessary.
Check that the downstream oxygen sensor is secure.
Repair if necessary.
If the vehicle is driven frequently in town, carry out the unclogging procedure (oxygen sensors and catalytic
converter clogging).
Check that the exhaust pipe is completely leak free.
Repair if necessary.
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.
Possible reasons for the destruction of 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.

FUEL PUMP RELAY
NOTESThere must be no present or stored faults.
IF THE RELAY DOES
NOT CLICKDisconnect the battery and the injection computer.
Check the cleanliness and condition of the computer connections.
In the Protection and Switching Unit disconnect the PEM connector and check the
cleanliness and condition of the connections.
Using the Universal bornier, check for insulation and continuity on the following
connection:
Injection computer track D1 connector C track 1 of the
Protection and
Switching unit PEM
Repair if necessary.
If the fault is still present, there is a fault in the Switching Protection Unit (the fuel
pump relay is in the Switching Protection Unit and is not removable).
Contact the Techline.

NOT OPERATEDisconnect the fuel pump.
Check the cleanliness and condition of the connections.
Check for the + 12 V feed on the fuel pump connector with the ignition on (see
Technical Note 8227 Wiring Diagram, MEGANE II, 456).
If there is no + 12V:
– disconnect the battery,
– disconnect the connector marked PPH2 in the Protection and Switching Unit,

Repair if necessary.
Reconnect the Protection and Switching Unit connector and reconnect the battery.
If the + 12 V feed is still not present on the fuel pump relay connector with the ignition
on, there is a fault with the Protection and Switching Unit.
Contact the Techline.
Check that the earth on the fuel pump connector is present with the ignition on
(seeTechnical Note 8227 Wiring Diagram, MEGANE II, 456).
