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.

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).

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,
– check the cleanliness and condition of the connections,
– using the Universal bornier, check for continuity on the following connection:
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).
Repair if necessary.
If the fault is still present, replace the fuel pump.

CANISTER BLEED SOLENOID VALVE
NOTESThere must be no present or stored faults.
Check the cleanliness and condition of the fuel vapour absorber bleed solenoid valve connections.
Repair if necessary.
Measure the resistance between tracks 1 and 2 of the fuel vapour absorber bleed solenoid valve. Replace the
fuel vapour absorber bleed solenoid valve if the resistance is not 26 ±4 at 23°C.
Check for + 12 V feed on track 1 of the fuel vapour absorber bleed solenoid valve with the ignition on.
If there is no + 12V:
– disconnect the battery,
– disconnect the connector marked PPM1 in the Protection and Switching Unit,
– check the cleanliness and condition of the connections,
– using the Universal bornier, check the continuity on the following connection:
Protection and Switching Unit connector PPM1 track 2 track 1 of the fuel vapour absorber
bleed solenoid valve
Repair if necessary.
Reconnect the Protection and Switching Unit connector and reconnect the battery.
With the ignition on, if the +12V is still not present on the fuel vapour absorber canister bleed solenoid valve
connector, there is a fault with the Protection and Switching Unit.
Contact the Techline.
Disconnect the battery.
Disconnect the computer. Check the cleanliness and condition of the connections.
Using the Universal bornier, check for insulation and continuity on the following connection:
Injection computer, connector C, track E1 track 2 of the fuel vapour
absorber bleed solenoid valve
Repair if necessary.
If the fault persists, replace the solenoid valve.
