Default IAT Sensor replacement

I have an 86 a/t showing code 23. How hard to change th IAT sensor? Haynes manual just says unscrew. Looks hard to reach without taking things apart.. Any ideas??

On my 86, I had to remove the plenum to access the IAT sensor. So unless someone knows some magical way of changing it, looks like that's what you're facing.

You might want to test it before you attempt to pull the plenum.

You need a PDF reader, such as Adobe. The reader is free at their site. The PDF is from the FSM and will help determine if it is the sensor or associated wiring.
