Coolant Temperature Sensor
- Connect ohmmeter leads to sensor terminals. With engine cold and ambient temperature below 90°F (32°C), resistance should be 500-1000 ohms. With engine hot (normal operating temperature), resistance should be more than 1300 ohms.
- If not to specifications, replace coolant temperature sensor. The sensor will continually change its resistance with changes in engine operating temperature. This device is NOT a switch.
