Oil Temperature Switch
1. Measure the resistance with an ohmmeter across the switch
terminal and the switch body.
2. If 0 ohm is not indicated in the oil temperature at 55 °C (131 °F)
or more, the sensor is faulty.
3. If infinity is not indicated in the oil temperature at lower than 53
°C (127 °F), the sensor is faulty.
