I think that is the TPS in the first pic and the IAC is under it.

ok well, now that your saying its the 1 below, what do I do with the wire after I take it off?

look at the other picture, what is it called?

The top one is the throttle position sensor or TPS, you probably have to remove the whole throttle body to get the IAC off. I dont know how you test the 420a IAC

Yea I saw that there were 2 screws holding it down. It will be quite a job to get it unscrewed as there is no space for screwdriver there

Anybody know how to fix or test an IAC? and how to tell if its good or not?

Most temperature sensors use resistance to send to the ecu. If you get a multimeter you can test to make sure the the resistance matches the degrees or that it changes at all

The IAC is not a temperature sensor, I think you are referring to IAT - Intake Air Temperature sensor.

To remove the IAC, you will need to unplug the IAC and TPS connectors, remove the intake duct, and disconnect the throttle linkage. Remove the whole TB, then you can get to the IAC.

Check resistance between pins 1 and 4, then again between pins 2 and 3. The resistance should be 38-52ohms. If it tests good, this would be a great time to clean the TB and IAC, before reassembling.
