GF07.04-P-5026-04M Coolant Temperature Sensor Function
- up to model year 08
Component Identification
The NTC resistor integrated in the coolant temperature sensor (B11/4) alters its electrical resistance in line with the coolant temperature.
NTC is the abbreviation for " Negative Temperature Coefficient", which means electrical resistance falls as the temperature increases (hot conductor).
