This question is mainly for boosted tCs, but it would be interesting to see what those with just headers or S-pipes are getting.

I've had the Turbo Toyotas kit on for a little over a week now, and i got the CEL since its been on. Todd said he has not gotten it on his ohter kits, so he wanted to know what code it was.
my buddy, amdforever, hooked up his scangauge and the code was p0031.
I did a search and this is what I found:

DTC P0031 OXYGEN SENSOR HEATER CONTROL
CIRCUIT LOW (BANK 1 SENSOR 1)

Now, this does NOT seem to be the same code that others get with headers and what not they they fix with the anti-fouler. I believe that code is p0420.

I'm just wondering, for those that are getting the CEL, if you had the code read, what code it is, and what that code meens?

So far, it seems like the p0031 is a damaged primary sensor. There was even a TSB on it. Please correct me if I'm wrong.

 

THANKS FOR NOTHING!
j/k
Well, here is what I found so far:

But my vin is a good 40,000 after the end vin on that TSB.
So it looks like warantee wouldnt' cover it (especially after they see my turbo!) so would a new 02 sensor fix it? The first one in the down pipe?

 

Just take it out, you dont need that o2 anyhow. you can tune without it.

 

You took yours out completely and you get no CEL?
Is it just dangling there, or did you actually disconnect it from the cable? And what do you have plugging the hole?

 

Sorry, BEFORE i disconnected it, i didnt have a CEL. I just disconnected it. Putting the car in open loop always, making it a ton easier to tune off partial throttle and i also picked up a little mor HP on the dyno.

 

Oh, so NOW you have a CEL?
and I'm assuming you have the sensor screwed in the downpipe but the wire disconnected from the cable?

I'm hopeing my tuner doesn't have an issue with the partial throttle with the new AEM F/IC, but I also need it to pass smog. As long as I dont' have a CEL, I'm good.

 

Correct

 

i got an obdII scanner and when my light came on ( 6 miles after driving with the turbo on it haha ) i got 2 codes. one being the no cat code. and the other was saying htat the car was running overly rich(in closed loop only) even with the antifoulers on the s-pipe i still got the cat code kinda upseting but im not too worried about it

 

I have a total of 0 codes....heheh

 

Nice.
It's looking like once I get a new primary sensor, i won't have any codes either. I just dont' want to drop $200 on a new sensor and not have it fix the problem.

 

Is your car not running right? Or just has a CEL? If its running fine I wouldnt worry about it.

 

Well, I haven't gotten tuned yet, so no, it's not running right, but that has nothing to do with the CEL.
I just want it gone so I can pass smog, and so if it DOES come one, I know it's for something I need to know, not something I did to it myself.

 

lol, i think i got this code one time when i forgot to plug my o2 sensor in.

 

HEY! NO FAIR! I figured this out at 5:00 and you didn't post till 5:30!
but yeah, that was it. My primary 02 sensor wasn't plugged in!
disconnected the battery, cleared the code, went boosting all around my neighborhood and still no code!
Thanks guys!

 

Yeah I forgot that while installing my brothers kit. It happens.

 

Ah, NOW it comes out!!!

 

plug it in, phil. plug it in...

 

Phil: "I thought you plugged it in, Todd!"
Todd: "I thought YOU plugged it in, Rob!"
Rob: "I thought YOU plugged it in, Phil!"
Phil: "I thought YOU plugged it in, Todd!"
Todd: "I thought YOU plugged it in, Rob!"
Rob: "I thought YOU plugged it in, Phil!"
...

 

^^^haha, put that in your sig

 

DAMIT! CEL came back on.
It's gotta be something else this time, so I need to go get it read.
