Petal sensor

[Hooptybass]

Im looking for a petal sensor for my 94 burb i think is going bad . I would like to if possible buy one from somebody or even borrow one to see if thats my problem . its throwing a petal code so im thinking it is

Whats the code?

The app is triple redundant with limp modes when you loose redundancy.

off the top of my head its had 22 24 and 26 or 27 i belive ... But i went back to Mech pump and only use the petal for the trans since i didnt add a TMC and sensor on the pump when i did the change over

I just checked and atm its throwing a 22

Ah, I see.

Try unplugging in and plugging it back in. Sometimes the contacts get "crusty" and this re establishes good contact.

Have you considered ditching the stock PCM all together and going with a stand alone controller for the 4l80e?

Makes things much easier to set up the way you want them.

Ya im just about to that point ... i just havent priced out a tps and tcm . i was working great for about 6 months now im not sure if im having petal problems since my TC wont lock up.

I believe about 500 bucks will get you a compushift kit.

As far as I know, that's everything you need.

You can program shift points, downshift, upshift, lockup, etc.

It even has a tap shift option iirc.

Leroy sells it through pmd cable and I think he's a dieselpage vendor.

Sounds to me like it would fix a lot of your pita problems in one fell swoop.....

I may have to look into that.. but im sure i will still need a tps correct ? Thanks for lettin me know where to look .. I still will try and find the stock stuff if it will be cheaper but hell at this point i dont know

Also check out the DS4 to DB2 conversion guide that Bobbie Martin wrote. That gets you in the game on what TCM you need and using the TPS on the injection pump, etc.

Very well written and the wiring part about swapping the pins on the PCM harness isn't all that bad.

I'm making a standalone DS4 harness to test run engines on the stand, that's been a little harder.

Ive got the book and theres lots of good info in it and followed it almost religiously ... cept when i got to the petal,tcm and tps ... my local shop said aww you dont need to do that . we can do it w/o all that and it will still work . well im still fighting with it 2 years later =( works great sometimes

im bout to bite it and buy the remaing stuff and wire it in
