Test 14 - Coolant Sensor Calibration Check
Disconnect coolant sensor connector. Connect ohmmeter between terminals No. 1 and No. 3 of coolant sensor. Ohmmeter reading should be 400-6000 ohms. If resistance is not okay, replace coolant sensor. If resistance is okay, connect ohmmeter between coolant sensor terminals No. 1 and No. 2. Ohmmeter reading should be 176-3900 ohms. If resistance is okay, proceed to TEST 15 . If resistance is not okay, replace coolant sensor.
