I'm driving a 1992 Saturn SL2, and I recently received two service engine soon codes, the first one being my IAT sensor may be faulty, and the other being that my EGR may also be faulty and need replacing.

The guide I was looking at says that the sensor should be in the air intake duct, but I've looked through the whole thing and I can't find anywhere that it might go in.

Well, I could appreciated any and all help trying to locate this damn thing.

its just to the left of the air filter,if you can't find it, maybe it or the wires got knocked loose.

lots of times the EGR can just be cleaned out
