outside temp sensor Sign In
2008 Mercury Milan. 2.4 4cyl, 14,500mi.
The display gives only the temp the heating system is set at, not the outside temp. It just started this. Could it be the sensor?
Is the sensor the small matchbox size object to the left of the hood release behind the grill?

Re: outside temp sensor Sign In
It's possible but you would need a professional scan tool to be able to access the sensor data to confirm it.

Run a diagnostic on the system at the ac control panel.
See if there are any trouble codes being stored.

Quote
- To enter the self-test, press the OFF and DEFROST buttons simultaneously and release, then press the AUTO button within 2 seconds. The display will show a flashing blower icon for 20 seconds, after which all vacuum fluorescent segments will be displayed if there are no on-demand DTCs present. If DTCs are present, the HVAC module - EATC or HVAC module - DATC will display "00 00" and then on-demand DTCs. Record all DTCs displayed.
