Outside Air Temperature Indicator Calibration: Description

The outside air temperature sensor is located behind the center of the front bumper. The gauge control module uses measurements from this sensor, along with data provided by the HVAC control unit/climate control unit that is transmitted via the B-CAN communication bus 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 heat soak the outside air temperature sensor and cause inaccurate readings. Logic has been written into the gauge control module to help prevent abnormal or fluctuating outside air temperature indicator readings.
