Runs great, but it's throwing a "bank one lean" engine code. The same as GODLESS and his kit. I've tried the NonFouler mod for the second o2 sensor to get rid of it but to no avail.

What would happen if I did the same mod to the first sensor?

Am I just going to have to buy a little scanner and blow out the code every time it comes on?

Is there an edge to the Universe or does it go on forever?

Answers? Questions?

 

Sounds like you need a tune...

 

So the non-foulers that came with the kit are installed correct?

 

The kit comes with a pre-tuned piggy-back ECU unit and the car is running just perfect. They did a wideband air/fuel on the dyno and it was running perfect. So the error isn't in the tuning it's in the instrumentation.

As for the non foulers that came with the kit...there are none. It's not SUPPOSED to need any. These are the $5 special at your local AutoZone.

 

Um, your kit should have had some. Unless something has changed Turbonetics was including them with every kit for just this reason.

 

I'm sorry, misunderstanding. The kit comes with one for the FIRST o2 sensor. That was installed, and it was throwing a code.

So, i bought the 2 - 18mm guys for the SECOND sensor to give that a shot. And it's still throwing a code.

That's where we are now. Sorry, bout that.

 

Hmm, have you called Turbonetics yet? Just curious. I'll ask my guys over there if they have any ideas.

 

Well, it's 10:20 here 8:20 in Cali. If I know Californians they're not working 'till at least 9.

There's always o2 sims, but I shouldn't have to shell out $90 or whatever for one of those suckers just to make Turbonetic's kit work like it's supposed to. I'm gonna give them a shout too, just gotta pretend to get some work done today as well.

 

Welcome to the life of codes!!

No you shouldn't. They are already at work though. 8-5 PST. Give them a call at 805-581-0333 and ask for Reggie Wynn.

 

Left a message for Reggie to call me back. We'll see. Took me like a week to get those folks to call me back when they sent the wrong downpipe.

 

Reggie should be pretty repsonsive. He is a manager there and usually gets back to people pretty quick..

 

You weren't kidding. Already called me back and said he'd have some sort of an answer for me in an hour or two.

'course, he also asked if I was "this ideapimp guy." Seems somebody was watching the threads. I'll keep you folks posted.

 

Yeah brother is ALWAYS watching :D

 

Ok, solution I'm about to try is as follows: apparantly the "o2 extender" as they are calling it, is made for the 2nd o2 sensor, not the first. That's the one furthest fromthe engine, behind the 2nd CAT.

So, I gotta take it off the first sensor (where it is mistakenly mounted) crawl under the car, take off my, ahem, "homemade" extender made from two non foulers, and replace it with the extender that came with the kit.

Hey, a free fix is a free fix. I'll try to give it a shot tonight and we'll see how it goes. Man, this real job thing gets in the way of my car habit. This blows.

 

LOL I thought it sounded funny that you used the extension on the first one. You are in good hands with Reggie. He'll get it worked out for you. And trsut me without my day job thats all I would do...

 

I have been havin the same problem what are your AFR readings under WOT.

 

Dam, you used the extender on the primary 02 sensor? That's what controls the AF ratio on the ECU. So basically the ECU was running the system and telling you too lean.

That's good that the computer is doing what it is supposed to. I wonder if this mod could be used to add more fuel for higher-boost and no piggy-back fuel computer. You should remove the spark-plugs to see if they are fowled.

 

Ok, extender is off the primary sensor and now is living large back on the secondary. It's a little scary putting it under there. It sure comes close to the K member now.

Took the car out for a spin and so far, no light. We'll see if my wife throws a code on the way to work tomorrow. If not, I say "fixed".

Oh, yeah. Good idea bout checkin' the spark plugs. I'll give them a looksie tomorrow. I'm beat down today.

More later....

 

Ideapimp,

I think I know what your problem is

I had the same problem you did The P0171 "bank 1 too lean" poop. I checked all wiring and tuning, but couldn't find nothing wrong and even after the battery reset trick, the CEL would still pop up after 10-20 miles....

The solution that cured my CEL :o ..... it that one of the vacuum tubes being loose

So please recheck ALL your vacuum tubes especially the ones that gets spliced with the factory black tubing from the throttle body to feed your BOV/WG/Boost controller.

If you had used back the factory hose clips/fasteners, it MAY seem secure but are actually loose. Just give a thug and you'll see what I mean. Secure the suspect nipple with the worm gear fastener and the CEL is eliminated.

Theory : All the tubes you see gets routed to the vacuum block (big square plastic box) The Toyota pressure sensors are located in the box and monitors the vacuum levels. Where there is a lack of vacuum in ANY of the engine bay tubings which affects the proper signal feedback, the pressure sensor will send the signal back to the ECU and the non-factory parameters would trigger the P0171 code... :o To get a clearer picture, please refer to your VSV (Vacuum Switching Valve) wiring diagram found in the tC service manual.

DO NOT go out there to buy whatever possible hardware solution until you have tried my suggestion... For me, it has cured my CEL permanently :D I spent stupid money and time and I now give you this piece of free advice.

Logic 101 : Since it is the 1st OXB1 registering "too lean", it makes good sense that the problem is pre-throttle and not AFTER the 1st O2 sensor... Those who have offered the MMW O2 trick need to think about this....

Cheers and hope you will enjoy your Turbonetics kit soon....
