Well what's the rest of the story.
What does the voltage say when you have it hooked up and you open the throttle plate to wide open?
Alright. I just had to go get the TPS and my S90.
I check the wires.. and i have 4.8ish going to the TPS.. i take the throttle bodie off and use my test leads n aligator clips to test it..picture at bottom.. i even soldered them and keep them straight. The weird thing is i just stopped over at my car to get the turbo inlet size to i can make a boost leak check. And i found out that threw my SUPER AFC theres a option for sensor check. And im almost positive the third one is the tps. Cause its within the. 5 range when moved and i got it to .49 .50v and when i put the pedal to the floor it gos to 4.79ish.. so i think i got that set right. Idk why i cant get them numbers when im checking it under the hood tho?..confusingIt doesnt look like it can be installed backwards because if the TPS is turned to read 4.8v the throttle body wont open, or if it is installed wrong the throttle plate wont open, at least from my looking over of things. Unless you have the jumpers backwards or something?
So I wrote down the pin number, wire color and what it does.
1g TPS
1- Green/Red (+5v Sensor Power)
2- Green/White (TPS Output Volage)
3- NC (no connection)
4- Green/Black (Ground)
(Thanks to Steve's Post in another thread)
Depending on how you are checking it since you have to get to the bottom bolt to be able to move the TPS around, if you move the fuel rail then you can just probe the connector itself. Positive going to where the green and white wire is and negative going to the green and black wire. Just dont cram the probes into the connector. They should just slide in pretty well with no major binding and then check it.
If you are taking the throttle body off then you will have to use jumper wires.
I just probe the connector but I am able to since I am using a 2g connector which comes with extra wire. I just slide by throttle body on the studs a little bit test and adjust it and bolt the throttle body back.
Did you ever take a pic of your tps?I for the life of me messed with trying to put the tps on the throttle body to have it work like the voltage was describing and the only way I could get it is if the throttle plate was about half way open. How the tps is designed means that it can only open one way which is with the throttle plate opening.
Maybe some wires were crossed or something. But I'll look at my tps that I know is at .5v and take a picture so you can compare them.
If there is no vacuum leak it could be the throttle plate being open too far. If that isn' it it could be in the cooling system. These engines should operate between 185-205 degrees, if it isn' the computer will feed it more air to try to get it to operating temperatures.
