Coolant Temperature Sensor/Switch (For Computer): Testing and Inspection
OPERATION
-
The engine coolant temperature sensor functions to convert the barometric pressure to voltage, and to input that voltage (as signals) to the engine
control module. The engine control module, based upon those signals, regulates the amount of fuel injection and the fast-idling speed when the
engine is cold.
