Throttle Position Sensor: Testing and Inspection
COMPONENT DESCRIPTION
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.
