Cadillac Catera and Cimarron Forum Discussion, Catera outside air temp help in Past Cadillac Vehicle Discussion; Help,
I have a 1998 Catera whose ambient/outside digital air temp reading always displays a "F". Sometimes on cold days ...
What he said, if you are getting a "F" reading it means
that the sensor is gone, like mine was. I later found it, rewired and hooked it back up.
Or the sensor is shot.
It ez to tell look for 2 hanging wires by the drivers side fog light.
