Transmission Fluid Temperature Sensor (535)

Temperature Sensor, Gearbox Oil, FA 57 (535)

Main use
To inform the control module of the current oil temperature.

Transmission Fluid Temperature Sensor (535):

Type
The sensor is an NTC resistor in a metal casing. The characteristics of the NTC resistor mean that the resistance drops as the temperature rises.

Activation
The NTC resistor is powered with 5 V through a pull-up from control module pin 21(B) and is grounded through pin 31 (B).
