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.
