Battery Temperature Sensor

WARNING: This page is about a different car, the 2011 Infiniti M37. However, it is still accessible from the selected car via links, so may be relevant.

Battery temperature sensor is integrated in battery current sensor. The sensor measures temperature around the battery.

The electrical resistance of the thermistor decreases as temperature increases.
