Ambient Temperature Sensor
WARNING: This page is about a different car, the 2011 Lincoln MKT. However, it is still accessible from the selected car via links, so may be relevant.
The ambient temperature sensor signal is received by the dual-zone HVAC module and indicates the outside air temperature. The ambient temperature sensor is located in front of the radiator below the hood latch.
The ambient temperature sensor signal is not the sole factor considered by the dual-zone HVAC module for the outside air temperature display. Therefore, the ambient temperature PID monitored with a scan tool may not exactly match the display. For information regarding the outside air temperature display, refer to HVAC - CLIMATE CONTROL SYSTEM - GENERAL INFORMATION AND DIAGNOSTICS article.
