Where is the tps? 1990 305. Picture.

I have a 1990 Camaro 305 and need to find the tps to check it and or replace it. I have been looking for it and cant find it. Here is a picture if you could paint something on this to show around where it should be or what ever. Plus would i have to take anything off to get to it? Also I dont exactly know what a throttle body is. Everyone says its located on the throttle body and i dont even know where that is. I'd appreciate anything.

I hope this will help. I think this picture will be similar to yours. Take the air cleaner off and start looking. It's on the throttle body. It's part number 26 that helps.

Throttle body is what the air cleaner sits on. Take off the cleaner and the TPS is on the passenger side under the air cleaner next to the IAC motor. The diagram provided does not represent the actual part for your year.
