Sensor Test

Coolant Temperature Sensor Resistance Test:

1. With key off, disconnect connector from coolant temperature sensor.

2. Connect ohmmeter across coolant temperature sensor. Resistance should read as follows;

- 700 to 1,000 Ohms at approximately 200°F (operating temperature).
- 7,000 to 13,000 ohms at approximately 70°F, (room temperature).

3. If resistance is not within specifications, replace sensor.
