Coolant Temperature Sensor/Switch (For Computer): Description and Operation
ENGINE COOLANT TEMPERATURE SENSOR
The Engine Coolant Temperature (ECT) Sensor supplies the Engine Control Module (ECM) with a signal describing the temperature of the engine
^ Injection period
The sensor incorporates a temperature-sensitive resistance with a Negative Temperature Coefficient (NTC). The sensor is supplied with a stabilized
The voltage across the sensor is a function of the engine temperature and, therefore, of sensor resistance. Voltage can vary between 0 V and 5 V.
The engine control module (ECM) uses substitute values if the signal from the engine coolant temperature (ECT) sensor is missing or faulty, however,
The engine coolant temperature (ECT) sensor is mounted in the thermostat housing.
