ENGINE COOLANT TEMPERATURE SENSOR

OPERATION

The engine coolant temperature sensor provides an input to the powertrain control module (PCM). As coolant tem-
perature varies, the engine coolant temperature sensor resistance changes, resulting in a variable input voltage to
the PCM.
When the engine is cold, the PCM will demand slightly richer air-fuel mixtures and higher idle speeds until normal
operating temperatures are reached.
The engine coolant sensor input also determines operation of the radiator fan.
