Coolant temperature sensor, location/task/design/function

P15.00-0003-06

Function

The NTC resistor (3) integrated in the coolant temperature sensor (B11/3) alters its electrical resistance in line with the coolant temperature.

NTC means Negative Temperature Coefficient; which means that the electrical resistance (R) drops as the temperature (T) increases.
