	Coolant temperature sensor, location	Engine 119		GF07.04-P-5026-02E
		Engine 120		GF07.04-P-5026-02F
	Coolant temperature sensor, task	Detecting the coolant temperature and supplying information to the ME control module, and to the automatic air conditioning control module (N22) or air conditioning control module (N19)
	Coolant temperature sensor design			GF07.04-P-5026-01F
	Coolant temperature sensor, function	The NTC resistor integrated in the coolant temperature sensor (B11) alters its electrical resistance in line with the coolant temperature. NTC means negative temperature coefficient, in other words the electrical resistance becomes less as the temperature rises.
		Example:
		Coolant temperature	resistance
		20°C	2500 Ω ± 5%
		80°C	325 Ω ± 5%
