!OMG! I invented a SIMPLE way to set TPS !!!

[PorterzSupra]

Okay, I think I found a REALLY SIMPLE possibly even more accurate way to set TPS. Okay heres all you do.. reset your computer from any codes it might have. Turn TPS CC all the way then jump E1 and T. Okay now turn on the ignition you should get a constant fast blink of check engine. Now SLOWLY turn TPS CW untill it stops blinking and displays code 51. Okay now SLOWLY turn TPS CC untill it starts blinking fast again, tighten and re check. NOW! hit the gas VERY slightly, it should go from blinking fast to code 51 under very light throttle. YOUR FINISHED!!!!

Now you know the ECU detects even the slightest throttle position not based on your meter but actual reading based on your car and your throttle positiion!!! And you also know the ECU detects closed throttle at rest or you would get a code 51 =)

You can do this with one person by moving the TPS very slightly and re-checking (thats what I did) or with 2 ppl you can do it really quick.

No meters
No taking anything off or apart
No feeler guages!!

Good job Porter.. I don't think you invented it because it was posted yesterday, but +1 for efforts... I don't suppose it idles any better does it?

 

[PorterzSupra]

well the base idea was posted yes but just to check if it was working or not, not to set it, I kinda adopted the idea to set the TPS =)

Cool man, Again, does it idle any better now?

Now that the tps is set properly, I would recheck your timing as I could not set my timing with the TPS out of adjustment??...

gay self quote..Originally Posted by Joel W.
If it does not give a code, I would try adjusting it the TPS until it does??

 

[PorterzSupra]

well yes its slight better, now it wont die unless I rev it up to 3-4 grand and let off.. I think it was a combination of TPS and something elce... I think the turbo is too close to the MAF and IDL hose. There is no accord pipe, MAF and IDL turbe is about 4 inches from turbo so I think the suction/swurling from the fins when I rev it up gives the MAF a false reading?? I now have soot coming from my exhaust for the rich mixture when I let off =(

 

[PorterzSupra]

The possibilitys..

Cooltant temp sensor

MAF (Being too close to the turbo)

FPR (but the guage shows consistant pressure)

02 sensor? (too close to the turbo?)

OMG! Porter learns the difference between correlation and rote!

 

[Joel W.]

<Thumbs through dictionary real quick, Then LOL>

 

[jetjock]

There are five levels of learning. Rote is at the bottom while correlation is at the top. Roughly speaking it's using a knowledge of what the end result should be to recognize there are many ways to skin a cat. Since he went right from the bottom to the top it's quite a breakthrough

That said, if he'd used a meter he'd only need one person and it'd be quicker. Plus there are at least two ways to use a meter for TPS setting. You can either connect it directly to the TPS as the manual states or, using Porter's method, connect it to Vf. Since Vf outputs a high when a code is set he wouldn't need to look at the check engine light.

Unfortunately, that check engine light isn't gonna help next time he needs to use a meter for something else....

 

[PorterzSupra]

No I can read my meter but it says 5 not 0 like your guys said to start off and it only goes to 6 when I turn the TPS, its not really working idk..

 

[IHI-RHC7]

You have it set to continuity?

 

[PorterzSupra]

it was set to ohms like it suggested in the pic, its ok its set now though

 

[mkIIIman089]

Meh, TSRM worked fine for me. Plus it allows you to test at more then just 0% open to make sure its working right.

 

[jetjock]

Both sections of the TPS should be tested. The IDL contact can be checked and set several ways but since the throttle angle portion has no adjustment you have to live with what it gives you. The absolute best way to test the throttle angle part is with a scope. A TPS will develop a flat spot around the throttle angle position you normally cruise at. (That's around 25% for most cars but who knows with this crowd).

An ohmmeter will show this spot (as will a voltmeter with the TPS connected) as long as you're careful to watch for it but a scope will show even the slightest problem. It gives a nice picture of what the TPS signal being sent to the ecu looks like. If you really want the ability to track down problems in EFI you need a scope.

Cruise is 22>24% here

Porter: Now you have your magic setting chuck the meter on and measure the values write em down and if you need to set it again you can do so single handed and a bit faster than jumping in and out of the car!
