Coolant temperature sensor function - GF07.04-P-5026-04M
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 "N egative T emperature C oefficient", which means electrical resistance falls as the temperature increases (hot conductor).
Example:
