Battery Temperature Sensor: Description and Operation
BATTERY TEMPERATURE SENSOR
PCM INPUT
Provides a signal to the PCM corresponding to the battery temperature.
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 Powertrain Control Module (PCM) to vary the battery charging rate. System voltage will be
higher at colder temperatures and is gradually reduced at warmer temperatures.
