Coolant Temperature Sensor
WARNING: This page is about a different car, the 2013 Nissan Leaf. However, it is still accessible from the selected car via links, so may be relevant.
The coolant temperature sensor is detects the coolant temperature. This sensor uses a thermistor that changes its electrical resistance according to the temperature. VCM detects a voltage change according to electrical resistance change.
