Air Temperature Sensor ( Ambient / Intake ): Description and Operation



GF07.04-P-6070MAR Component Description For The Intake Air Temperature Sensor
- refinement package
- as of model year 09



Component Identification:






Location
The temperature sensor is located at the left rear on the variable intake manifold.

Task
The temperature sensor detects the intake air temperature to allow correction of the ignition angle and injection quantity.


Component Identification:






Function
The NTC resistor integrated in the temperature sensor alters its electrical resistance in line with the intake air temperature. The ME-SFI control unit (N3/10) applies a sensor ground and evaluates the resistance corresponding to the intake air temperature.

NTC
NTC Negative Temperature Coefficient", which means: means " C The electrical resistance falls as the temperature rises (heat conductor).
