1996 Ls400 Temp Guage

[attrabeutz]

I have a 1996 LS 400. The outside temperture guage is reading -22F.

Any ideas where I need to start to troubleshoot this?

Thanks

I think you should start with the ambient temperature sensor at the front bumper. It might be dirty or something.

Good luck.

Reading -22 is a pretty sure bet that the OAT sensor connection is completely open or else the sensor (thermistor) itself is. If I remember correctly 4800 ohms is about 32F.

Are you sure it is not -22 outside? Just kidding! I could not resist! :D

I agree with the others - probably the sensors.

Good luck!
