if you have TPS codes, replace it.

are you sure the volt meter is setup correct? it will show 5.09 on the green if you have it on millivolts

what happens when you rotate the tps? can you get the green wire voltage to go lower?

well by rotate do you mean move the rubber outside about an 18th inch side to side because thats all i can do with it...when i do that it doesn't change the voltage at all. you might be right about millivolts...i'm new to voltometers

you loosen the two screws on it; they attach it to the throttle body. then you can rotate it slightly to get the voltage that you want. sometimes you have to elongate the holes.
