Battery Temperature Sensor: Description and Operation

DESCRIPTION
The battery temperature sensor is attached to the battery tray located under the battery.

OPERATION
The battery temperature sensor is used to determine the battery temperature and control battery charging rate. This temperature data, along with data from monitored line voltage, is used by the PCM to vary the battery charging rate. System voltage will be higher at colder temperatures and is gradually reduced at warmer temperatures.

BATTERY TEMPERATURE SENSOR-PCM INPUT
Provides a signal to the PCM corresponding to the battery temperature.
