	Intake air temperature sensor, location	Engine 104, 111 (HFM), Engine 119, 120 (ME1.0) On engine 104 ME, 111 ME, 112, 113,137 the intake air temperature sensor is integrated in the hot film mass air flow sensor.	GF07.04-P-2100-01F
	Intake air temperature sensor, task	Records the inlet air temperature and sends a signal to the engine control unit. The signal is used for calculating the air mass. The amount injected and the point of ignition are influenced.
	Intake air temperature sensor, design	Plastic housing with a NTC resistor, 2-pin plug connection
	Intake air temperature sensor function	The NTC resistor integrated in the intake air temperature sensor, alters its electrical resistance in line with the intake air temperature. NTC means Negative Temperature Coefficient; which means that the electrical resistance drops as the temperature increases.
