Ok, so the code 31 went away and so did 51 when i switched ECU's and reset the efi fuse. Code 41 remains.

I do not get voltage between the following in any throttle condition with either ECU:

1) IDL to E2

2) VC to E2

3) VTA to E2

You're right, you're right..

Edit: Potential above!

Edit edit: You're doing good, just follow the TSRM broski.

1) There is no voltage between IDL and E2? (IG SW ON) (Throttle valve open)

I am in Hampton Roads, VA. I have guys locally, but they don't have any free time. I paid Soundslikesemi to install the walbro yesterday while I watched and worked on getting everything else ready. He also helped me get my timing dead on. I may ask him for a hand, but convincing him may require $$$ lol Not that I blame him.

I do not trust most people when it comes to working on my vehicles, so everything I know and do I have learned without taking any classes. Same way with my computer skills, and I work in IT.

I may make silly mistakes sometimes, but so far I have done pretty well and usually catch myself. lol There is much advice I have taken and learned from the guys on here who know more than me, ie: oil pump shimming, oil cooling systems, doing the head and block at the same time instead of half-assing it. I appreciate the help, and trust me, it keeps adding to what I know instead of going out the other ear.

Electrical troubleshooting is not exactly my forte, but I am trying. :hs: lol

No voltage between any of them in any throttle position regardless of the key position (on/off). I believe it may be wiring related. The engine harness is nasty, but it came with the ECU and igniter for a good price so I was not complaining. I may try Semi's one to see if it will work along with the good turbo he is bringing over.

Broski? Does that include 'sum ya-gah boms?!' :sarcasm:

I can see the typical "water gets muddier, thread goes on tangents, gets derailed" thing about to happen here. While that flow chart can be useful it's for dummies. Step 2 for example. If the MIL comes on or the car runs you have +B. Since it ran before the wiring must be good. Therefore changing ECU altered the entire troubleshooting approach. Put the old one back because this one may have problems. The last thing you want is to keep introducing more variables into the process. I'd put the old one back in because it's a know quantity, one you're already invested in, and pick up where you left off....

Ok, so I have put back the other ECU. Still only code 41. I am getting a better condition engine harness as well as the other turbo tomorrow. Hopefully that will help clear up some issues. As for the TPS calibration, you said there was a better way jet?

So no 51 when you press on the pedal with the TPS plugged in? And now no 31?
Click to expand...

No code 51 when I press on the pedal, with the tps plugged in. No code 31 anymore. I think the code 31 was a momentary thing. I drove the car a little more, just up and down the street once or twice and she will not go over 3K rpms.

We shall see if the code 41 is taken care with the new harness tomorrow.

Sigh. My intention all along was to impart an understanding of how it works so you could fix it yourself. It appears I've failed. Ah well, one last try:

You said you got a 51 with the TPS unplugged, therefore the harness is fine. We're back to the same place: if in diag mode you get 51 with the TPS unplugged but not with it plugged in the IDL contact is not opening. That's why the car ran well with it unplugged. You have a TPS problem. We always knew that but now we know which of the three causes of 41 needs to be addressed.

Either measure the resistance between IDL and E2 (TPS unplugged) for low ohms when the throttle is closed and infinity when it's open or look for 0 volts (TPS plugged in and key on) between IDL and E2 throttle closed and 5 volts throttle open. If you can get there set it for 0 volts without the feeler and 5 volts with the feeler. Or just set it to flash a 51 throttle cracked and no 51 throttle closed. Any of those will solve your problem.

If you can't get IDL to do anything pull the TPS off and check it. Make sure it's the right one and it's engaging the ears on the TB correctly. Your problem lies with the TPS and only the TPS...

This is what I meant in my original post, About not having the tps on the tb correctly. I've done that before. I'd put money on it if I were a betting man.

And here we make the assumption that I am one of the blind ones. I get sarcasm, and I realize it is frustrating to help me when I don't really understand exactly what you were saying. I also know when to keep my mouth shut and accept help even if someone is frustrated or cracking jokes because I don't understand. I do the same thing, and know I would never learn a damn thing on this forum if I took everything to heart. :biglaugh:

I hate electrical issues because I have never had to troubleshoot them before, so it is not always within my grasp when I do troubleshoot it. I will be setting the tps per the instructions that Jetjock suggested and we will see if that helps/fixes it.

Jet- I wanted to replace the harness anyways, it is badly chopped. I figured it wasn't the harness while I was studying it last night since the car drives fine without the tps and like crap WITH it. The funny part is, it did it both with AND without the tps plugged in at times, but it keeps changing its mind on what condition it wants to work under.

I appreciate the help.

Good luck.

Btw you assumed whitemike was talking about you. He assumed I was talking about SA. None of it is true. That's the internet for ya...

Oh, haha now I feel like an ass. :nono:

So anyways, I was feeling sick this morning and slept in until I had to go to work. Little did I know, I missed a perfect 60 degree and sunny day to solve the problem... Tomorrow morning will be a different story. Up at 8am. I am determined to solve this.

I do know the TPS is engaging the TB correctly, I have pulled it off and put it back on several times. I will check for the suggested voltages/ohms when I get home.

But one question, is there an aftermarket alternative? I want to upgrade to a nicer TB at some point, but I do not know much about this and I have not found any useful information, other than the Q45 upgrade.

Look..

If you TRY to fix a problem. I respect that. That's all most of us ask, is that you try.. Most people don't try to help themselves, and it becomes very frustrating for the people trying to help THEM. You all are clearly trying because we have 4 pages of questions. Well done.

Hope you understand, wasn't trying to insult, just making a funny!
