Charge air temperature sensor function - GF07.04-P-5039-02AM

Fig 1: Identifying Charge Air Temperature Sensor Function
G04839822

The NTC resistor (b) integrated in the charge air temperature sensor alters its electrical resistance in line with the charge air temperature. The ME-SFI [ME] control unit (N3/10) applies a sensor voltage of 5 V and evaluates the signal voltage in accordance with the charge air temperature.

NTC means "N  egative T  emperature C  oefficient", which means: the electrical resistance drops with increasing temperature (thermal resistor).

IMPORTANT

The connection assignment (polarity) of connection pin 1 and 2 is random.
