Note: Ensure that the coolant level is at the correct level before performing this test.
Start Cat ET.
Start and run the engine until the temperature reaches the desired range according to the test thermometer.
Monitor the coolant temperature on Cat ET. Monitor the coolant temperature on the test thermometer.
Compare the coolant temperature on Cat ET to the coolant temperature on the test thermometer. If the two measurements are about equal, the sensor is okay. If the two measurements are not about equal, there may be a problem with the sensor. Install a new sensor and verify that the problem is resolved.
