Task

The charge air temperature sensor detects the charge air temperature and transmits a corresponding voltage signal to the CDI control unit (N3/28).

Input and output signals

Direct output signals

Change in voltage for charge air temperature determination at the CDI control unit

Design

The charge air temperature sensor consists of a resistance with negative temperature coefficients (NTC) and a 2-pin plug connection.

Function

The NTC resistor installed in the charge air temperature sensor changes its electrical resistance according to the charge air temperature.

The CDI control unit applies a sensor voltage of 5 V and evaluates the charge air temperature according to the signal voltage.

The electrical resistance falls for an NTC resistor as the temperature increases.
