Yeah but if my TPS is inverted then at fully open it should be at 0-0.5 volts. Mine isn't full open it's at 2.8 volts. But your saying it doesn't matter what sytle of TPS I have but if the car came stock with a TPS that at closed was sitting at 0-0.5 volts and was replaced with a TPS that at closed sits at 4.5-5.0 volts it would seem that would definetly make the computer a little confised. Unless someone here knows for sure that the computer will automatically adust for a change like that it seems I need to a. Find out what kind of TPS came stock with that car. b. Get a new TPS that at fully closed sits at 0-0.5 volts. and at fully open sits at 4.5-5.0 volts or inverse depending on what kind of unit I need. I could check the sweep this weekend to see if it's dropping signal but it still doesn't change the fact the unit isn't operating properly already from the tests I've run.

Ok I'm going to get a used TPS to throw in the car. While that's being done does anyone here have a 90-94 legacy that knows or could find out if their TPS is 0-0.5 volts closed throttle? Or if it's actually 4.5-5 volts. Thanks if anyone responds.

So again before I go out and buy new stuff. Back to the original question.

So my $300 fluke DMM won't work ?

I have the haynes version. That is the method I used. I'm not sure what u mean by check the sweep.

http://endwrench.com/images/pdfs/Fuel.pdf CLosed TPS is supposed to be at 0-0.5 volts Open TPS is supposed to be at4.5-5 volts However mine is exact oppisite. pins 2 and 4 on a 4 pin TPS connector with ignition on.

Ok I tried testing out the TPS wires by rotating them in my hands, and seeing if there was a short of any kind = no difference. I followed the wires to the harness and cleaned that up = no difference. Came back to this board and did some searching on TPS = didn't find much. Thought about it with my feeble mind a little bit I remembered one thing. The TPS was marked with white crayon at screw positon, which means some mechanic worked on it and either replaced or removed the TPS at some point. The QUESTION: What would happen on a subaru if the original TPS was a non inverted TPS and it was replaced by an inverted TPS????? Since the TPS is working correctly and I don't really see a problem with the circuit I'm hopeing that an inverted TPS would screw up a car built for a non inverted TPS. Thanks in advance.

Wow thanks alot Gary hopefully I won't screw up mine. I will try to do that tonight when i get home. Does the TPS have it's own connector to the ECU? Hopefully it will be somewhat obvious when I try the rolling trick tonight. I have a butt connector set and crimpers so if I do find faulty wiring I will be able to fix it on the spot

Ok cleared codes yesterday and checked codes again today only one left AT THIS TIME. code 31 TPS (or circuit) seems to be a problem

Yes Nipper I replaced the CTS as well as the sending unit underneath it. I cleared the codes yesterday after I got home from work, as well as retarding the TPS back to 4.8volts. I will check the car when I get home to se what codes it's throwing out now. Thanks again guys I will definetly keep you posted.

yeah but what do you think about the coils?

I did test the wires and they ohm out just fine however the coils they hook up to r about 600 ohms over spec but I'm guessing that's not to huge of a difference. So I haven't replaced them yet because I don't think 600 ohms is much of a concern

Also if I'm not supposed to clear the codes when am I supposed to clear them?

Sorry by reset I mean't clearing the codes. Now Cougar says that the code should go away by itself so should I try to clear the codes or not? Thanks for the info again OB99W. Your like a link guru LOL.

Fine fine that fuel.PDF contains everything I need apparently. I will consult my Hanes manual to see if it goes into further depth on resetting it. I will post tonight of tommorrow with any improvment.
