P0115 ECT SENSOR
P0115 ECT SENSOR
DescriptionINFOID:0000000001162581
The engine coolant temperature sensor is used to detect the engine coolant temperature. The sensor modifies
a voltage signal from the ECM. The modified signal returns to the ECM as the engine coolant temperature
input. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance
of the thermistor decreases as temperature increases.
