| 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. | |||
