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.

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:

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 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.
