Coolant Temperature Sensor/Switch (For Computer): Description and Operation
GF07.04-P-5026-04GA Coolant Temperature Sensor Function

GF07.04-P-5026-04GA Coolant Temperature Sensor 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, in other words the electrical resistance (R) becomes less as the temperature (T) rises.

Example:
Coolant temperature

Resistance

20 degrees C

2500 Ohms ±5%

80 degrees C

300 Ohms ±5%
