GF07.04-P-6110T Component Description For The Catalytic Converter Temperature Sensor
- except CODE (494) USA version
- except CODE (498) Japan version

Component Identification:

Location
The TWC temperature sensor is located on the oxidation catalytic converter above.

Task
The TWC temperature sensor detects the current exhaust gas temperature upstream of the oxidation catalytic converter and transmits an appropriate signal to the CDI control unit (N3/9).

Design
The CAT temperature sensor consists of a metal housing with a positive temperature coefficient (PTC) precision resistor and a 2-pin plug connector.

Function
The PTC precision resistor integrated in the CAT temperature sensor changes its electrical resistance according to the exhaust temperature. Electrical resistance increases as temperature increases.
