tps values

[mkiiichip]

And now we have an adjusted tps. (thank god)

I dont know, and dont care where you got the counter clock wise, clock wise, thing, but you have (or your source has) something backwards (and its not the car).

Now that you have this figured this out, please take a min and figure out where the confusion was (as it was on your end, since nothing was backwards, as you stated was the problem, multiple times)

There is nothing like learning, as long as you learn something.

Well the problem was the TPS was deflecting backwards when measuring in ohms and still is. Although after setting it going by voltage with the correct clearances it is working just fine!

I'm not really sure what to take from this... Adjust the TPS by voltage and not ohms?

I would need a working TPS that deflects ohms the proper direction to compare.

 

[hvyman]

I have never seen a tps deflect backwards.

Every time i set a tps it deflected normaly with a digital volt/ohm meter and everything checked out.

Idk what your problem was unless you had a slow ohm meter and you turned it too fast.

I'll eventually get a TPS that has been known to deflect properly to compare to.

Stupid question, but are you putting the TPS in right? The prongs on the throttlebody slide into slots on the TPS lever, they don't rest against it.

For the TPS to calibrate with voltage it *has* be deflecting correctly when resistance is measured. There can be no mistake about that. It's OK you're confused but it's not OK you continue to blame the TPS rather than even consider the error is yours. That type of thinking will not serve you well in the future...

DUDE!!!! That's it!!! Thank you so much for bringing that up! I remember a while back I tried that and it didn't seem right because they didn't want to slide in and started bending the plastic. Ever since I have always installed it with the flat end of the tps prong resting against the TB prong! I even brought that up to someone I don't remember who and they said my way was right so I guess i ruled that out.

Uhh I didn't mean to...? I have no problem admitting my mistakes. I was hoping this whole time it would be something simple like that but I guess I lost hope..

The TPS still was deflecting backwards no matter what installed properly or improperly and I don't know how else to say it. That is a diagnosis so someone CAN point out my flaws. Right? I didn't mean it any other way.

Thanks so much Poodles I'm going to install it that way and see if things change!

As long as you understand the TPS isn't/wasn't deflecting backwards. You only thought it was.

Yes of course it makes sense now, I mean I haven't tried it yet it will have to be later today. To correct myself it was deflecting backwards with the way I had it.

 

[whitemike]

Brian, shut up, you're wrong, JJ just made you his bitch. Take it like a man.

The car start yet? Vids? Pics? Cmon broski.

[jetjock]

No reason to try it unless you really want to see. As I said if it calibrated correctly using voltage it has to deflect correctly using resistance. Since you do not possess the power to invalidate Ohms' Law no other result is possible. Btw you didn't even need a meter to do this. You could have used the MIL...

 

[Bri7man]

MIL? I really don't know why but I swear on my grave.... when turning the tps counter clock resistance was shown and clockwise infinite was displayed. Maybe having the prongs beside the slots and not in them could have caused this? I don't know. I'm going to install it correctly and see what happens.

Mike- car idles smooth and so I took her out yesterday, oil pressure on the stock gauge is low going to hook up my napa oil pressure gauge to double check it sometime today.

It's usually easier to use a meter...although this may not have been one of those cases

 

[Bri7man]

Oh yeah JJ! Before all this I jumped the diagnostic terminals and literally just turned it until code 51 went out and that worked just fine. It's just I actually wanted to adjust it per tsrm this time and it freaked me out what I was seeing hence this thread.

I can get it adjusted easy it's just not the recommended way per TSRM. Mkiiichips voltage method worked great and that's awesome but I really need to slip the TB prongs into the TPS inserts and try it from square 1 again to see if there's any difference in deflection.

Anyways mike here ya go, cold start: http://s373.photobucket.com/albums/...mes a charm/?action=view&current=P3200082.flv

6 of one 1/2 dozen of the other although his method is good in that it verifies the type of signal the ECU actually uses. You can also use rpm. There are several ways of doing it once you understand how it works and what the ECU requires. Not that it needs to be done very accurately for stuff to work...

 

[Bri7man]

ECU supplies 4.5v in my case and requires .90mm of travel on the TPS counter clockwise to supply it? Right? In order to have correct throttle response.

 

[jetjock]

Kind of. When the ECU sees 5 volts it knows the idle switch has opened. When it sees 0 volts it knows the idle switch is closed. It uses that for a bunch of things, mainly for idle speed control and emissions fuel cut. The other part of the TPS is used to determine throttle angle. That part you weren't measuring. However, because the throttle angle part and idle switch part are mechanically connected inside the TPS, setting the idle switch also sets the throttle angle portion to a voltage that is above the level that will set the other (41) TPS code.

 

[Bri7man]

Ah, makes sense

 

[jetjock]

It does? Damn

Most people put way to much stock in the TPS when it comes to driveability. Try it: once you get everything fixed warm the engine up, unplug the TPS, go for a drive and see how much throttle response is effected. There may be a slight hesitation upon tip in but there usually isn't. The idle may be a bit funky but it's usually not. All depends on what else is wrong with the engine. On a good running one you won't notice much of anything...

 

[Bri7man]

Ha I definitely will. I think i experienced something similar tho. This is going to sound stupid but when I first got my car I thought the TPS was apart of "tuning" so I would calibrate it by hand ever so slightly until the throttle response would be as rapid as possible, basically jumpy.
