2018 F150 vehicles excluding Raptor built at Dearborn Truck Plant on or after 26-Feb-2018 and at Kansas City Assembly Plant on or after 10-Mar-2018 have the AAT sensor located in the right exterior mirror. The AAT sensor is serviced separately from the mirror assembly. If the vehicle is built on or after the dates listed above, do not add the sensor and harness behind the grill. If the sensor is missing from the right mirror the incorrect exterior mirror may have been installed. Refer to Ambient Air Temperature Sensor GSB G0000178 for additional information. The Workshop Manual (WSM) and Wiring Diagram have been updated for non-Raptor vehicles for the early and late build AAT sensor locations. The sensor location on Raptor vehicles has not changed.
