Circuit DescriptionThe coolant temperature sensor is used by the ECM to monitor the temperature of the enginecoolant. The coolant temperature is used by the ECM for the engine protection system, timing,and fueling control. Component LocationThe coolant temperature sensor is located toward the front of the thermostat housing. Shop TalkThe sensor resistance reading will match the following table if the sensor is functioningproperly.

Circuit DescriptionThe coolant temperature sensor (CTS) is used by the electronic control module (ECM) to monitorthe temperature of the engine coolant. The coolant temperature is used by the ECM for theengine protection system and the timing and fueling control. Component LocationThe coolant temperature sensor is located on top of the thermostat housing. Shop TalkMake sure the airflow through the radiator is not obstructed.
