where is the outside air temp sensor on my 2000 Grand Marquis?
100

Asked by mike44444 Jan 27, 2015 at 01:23 PM about the 2000 Mercury Grand Marquis LS

Question type: Maintenance & Repair

My outside air temp reads 127 degrees which leads me to believe the sensor is shot. One
forum said the sensor would be in the wire harness between the grill and the radiator. I
looked there and couldn't find it. Any ideas?

Found it! There is a bracket to hold the sensor in the right third of the harness channel. it fell out of the bracket and was hanging where I couldn't see it. Out side temp now reads correctly instead of 127 degrees. Whoo Hoo!
