Battery Temperature Sensor: Description and Operation
SYSTEM OPERATION
The battery temperature sensor is used to determine the battery temperature. 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.
The sensor is located on the bottom of the battery tray.
