measures pressure the other temperature, be careful what you use to clean it with no chemicals just shop air. I have never seen one go bad.

IAT wants electrical parts cleaner, it gets sooty.
MAP is a diaphragm that reads air pressure differential, it can go bad or wear out but usually doesn't until after a lot of miles.
pull the connector and use a deep socket on both, IIRC 1" 1/16 and 1" 1/8 are what you will need...
