GF07.04-P-6110GZ Component Description For The Catalytic Converter Temperature Sensor
Location
The TWC temperature sensor is located on the oxidation catalytic converter.
Task
The TWC temperature sensor determines the current exhaust gas temperature upstream of the oxidation catalytic converter.
Design
The TWC temperature sensor consists of a metal housing with a negative temperature coefficient (NTC) resistor and a 2-pin plug connector.
Function
The integral NTC resistor in the TWC temperature sensor changes its electrical resistance according to the exhaust gas temperature. Electrical resistance
decreases as temperature increases.
