Outside Air Temperature Indicator Calibration: Description

The outside temperature sensor is located behind the middle of the front bumper. The gauge control module uses measurements from this sensor provided by the climate control unit via the B-CAN communication line to display the outside air temperature. Because of the location of the sensor, it may be affected by heat reflection from the road, engine and radiator heat, or hot exhaust from surrounding traffic. These conditions can soak the outside air temperature sensor in heat and cause inaccurate readings. Logic has been written into the gauge control module to help prevent abnormal or fluctuating outside air temperature indicator readings.
