1990 Lumina Euro Coupe Posted July 5, 2004 Report Share Posted July 5, 2004 I cannot determine which sensor is the TPS on my 1991 Grand Prix. The repair manual shows the location on every engine but mine. :x Stupid Haynes. For the 3.1 it tells you to look on the drivers side of the car. Gee, thanks! Just pinpoint it for me! I am working on repairs, and am returning a code for TPS, which makes sense, since when you give it throttle, it bogs and dies. If someone could tell me where it is and describe it for me I would be gratefull. The Loomie is back up, and hopefully the Pree will be tommorrow.

god910 Posted July 5, 2004 Report Share Posted July 5, 2004 On the front side of the TB, it has a blue connector. (IIRC) There is the IAC, then just below that is the TPS. It's kinda L shaped. HTH. Quote Link to comment Share on other sites More sharing options...
1990 Lumina Euro Coupe Posted July 5, 2004 Author Report Share Posted July 5, 2004 On the front side of the TB, it has a blue connector. (IIRC) There is the IAC, then just below that is the TPS. It's kinda L shaped. HTH. Anyone have a picture? The only thing that I see under the hood of my car with any kind of blue on it, is in the back middle of the intake plentium. It has a very small blue connector at the tip, but the majority of it is red. It has some other connections running to it, so I don't really think that is it. Now there is a very large box on the top of the engine near there that looks as if it has four bolts or rods protruding into the intake. According to one websites description, a failing TPS reverts to a default "limp" mode and while the engine will not run at 100%, it is supposed to be enough so that you are able to get somewhere to have it repaired.(So I do attempt to find things out before I ask.) This will idle fairly well, but as soon as you give it throttle, it bogs. I still suspect it could possibly be it though. I'm going to replace it with one from a yard at first so that I am only out a couple of dollars if I am wrong. It is throwing a TPS voltage low code. All help welcomed!
