Condition
Catalytic Converter, Replacement, Rear Oxygen Sensors Not Required
Catalytic Converter (service part) no longer supports rear oxygen sensors.
Technical Background
Early build MY06 Passat were produced with three oxygen sensors per catalytic converter. Only four oxygen sensors (two per converter) are used for
OBD. Rear oxygen sensors -arrow- are not monitored by the ECM.
When replacing catalytic converter(s), the unused body harness connector(s) must be weather sealed for harness protection.

Service
Tip:
This repair requires that the rear oxygen sensor connectors be removed from the oxygen sensors prior to catalytic converter disposal. The connectors will
be modified to act as "covers" and "fasteners" for the body harness connectors.
