Engine Coolant Temperature (ECT) Sensor
Description
The Engine Coolant Temperature (ECT) Sensor is beside the thermostat. The ECT Sensor is a negative thermal
coefficient sensor.
Operation
The ECT sensor provides an input signal to the ECM. As temperature increases, resistance of the sensor decreases.
As coolant temperature varies, the ECT sensor resistance changes resulting in a different voltage value at the ECT
sensor signal circuit. The ECM uses the input to control air-fuel mixture, timing, and radiator fan on/off times.
Removal & Installation
1. Disconnect and isolate the negative battery cable.
2. Release the coolant system pressure.
WARNING!
Never remove the radiator pressure relief cap under any conditions while the engine is operating or hot. Failure
to follow these instructions could result in personal injury or damage to the cooling system or engine. To avoid
having scalding hot coolant or steam blow out of the cooling system, use extreme care when removing the pres-
sure relief cap. Wait until the engine has cooled, then wrap a thick cloth around the pressure relief cap and turn
it slowly one turn (counterclockwise). Step back while the pressure is released from the cooling system. When
you are certain all the pressure has been released, (with a cloth) turn and remove the pressure relief cap. Failure
to follow these instructions may result in serious personal injury.
3. Disconnect the coolant temperature sensor electrical connector.
CAUTION:
Remove the coolant temperature sensor when the engine is cold.
