Check of sensor, coolant temperature
1. Turn off engine
2. Remove the contact and remove the sensor from the engine.
3. Measure using multimeter 9510060-8 between the sensor’s two contact pins. The multimeter should display a value as shown in the adjacent diagram and graphic.
NOTE: The sensor is very sensitive to temperature changes. When measuring in the lower temperature ranges 0-40°C (32-104°F), it is sufficient to hold the sensor in your hand for the resistance value to drop rapidly.
