Coolant Sensor/Switch Test
- Disconnect coolant sensor/switch connector. Connect one lead of ohmmeter to sensor/switch terminal and other lead to ground.
- With engine temperature below sensor/switch operating temperature, resistance should be less than 10 ohms. With engine temperature above sensor/switch operating temperature, resistance should be infinite.
