Coolant Temperature Sensor Test
- Connect ohmmeter leads to sensor terminals. With engine cold and ambient temperature below 90°F, resistance should be 500-1000 ohms. With engine hot (normal), the resistance should be more than 1300 ohms.
- If not to specifications, replace sensor. The sensor will continually change its resistance with changes in engine operating temperature.
