The battery temperature sensor is located in the Powertrain Control Module (PCM). This CCD broadcast information is used to control charging system, engine and transaxle operation. The TCM uses the battery temperature signal to estimate transaxle fluid temperature. When the TCM detects lower temperatures, it adjusts the operation of the transaxle to allow for slower response of the valves and fluid. If a failure of the Transmission Temperature Sensor occurs, the TCM uses the Battery Temperature signal along with engine coolant temperature to calculate the temperature.
