Coolant Temperature Sensor
- Disconnect coolant temperature sensor connector. Using a DVOM, measure temperature resistance of coolant temperature sensor body. Measure resistance between coolant temperature sensor terminals. See Figure
. If resistance is not as shown, replace coolant temperature sensor.NOTE: Before coolant temperature sensor is removed, drain cooling system and refill cooling system if sensor is replaced.
- Check to ensure there is no continuity between each terminal of coolant temperature sensor and sensor body. If continuity is present, replace coolant temperature sensor.
