Default Ses P1274 P1283 P302

Getting 3 codes.. I kept resetting the ecu battery method and pedal method.

I have the Anti foulers installed and I also switched over my o2's from left to right.

I also put in new spark plugs recently too!

Turbonetics with no cat and +1 step colder plugs.

I need to pass inspection this month

Anyone else have a solution I can try?

Switch the position of the rear O2s if you haven't already. If that doesn't work we may need to look at using O2 sims.

I thought you were running the kit with the UTEC only and not the flash?

I am only using a UTEC. no flash.

I tried switching the O2s, but that didn't work.

It seems alot of people are getting these codes.

Has TN thought of placing there O2 extenders perpendicularly to the pipe rather than on an angle?

BTW, where can you get O2 simulators? I stopped by a locla shop and they said they are getting to be scarce because the government is coming down on them!

Yes but most of those people are running the flash. Which swapping spots on the pipe has fixed.. www.gspec.com can still get O2 sims..

I switched o2's also, doesn't work. Keeps coming back. Could it be the back pressure from the stock exhaust that is pushing more gasses into the o2 extenders?

I doubt thats the issue. For some reason this seems to be a G35 issue. The Z guys don't seem to get this as much or at all and all the ones I have talked to the issue was cured by swapping O2 positions. Hmm, I'll have to see if anyone has tried O2 sims yet.

it is getting frustrating to pull out the laptop everyday and erase the same 1274/1283 codes.

I just passed inspection last week! I don't have the CEL for the whole Summer. Then last week I changed out my Borla TD to put the AAM 3" single exhaust in and the CEL was on. I reset it and no more CEL for a whole week already. Hope you will get a fix soon.

Cant u just reset the ecu like 10miles from inspection? Will the ecu store the codes if u dont drive it a certain distance or can u just trick the ecu into thinking its okay for just a few days or so?

I'll talk to Turbonetics and see if we can try O2 sims but its hard to determine if thats the fix when none of the Turbonetics cars get that code.

So I need to pass inspection ASAP. I've talked to Reggie and he asked for pics of the DP. I'm going to take pics of the DP tomorrow. I am pretty sure I have the extenders on my DP. I've also swapped the O2's last time it was in the shop along with throwing in a set of anti-foulers.

I got rid 300 code (probably from my last plug change)

I just need to get rid of the 1273 1284 codes ASAP. I need to pass inspection!

So I drove it home.. about 9 miles from my friend's the codes have no come back up yet.
I did another O2 swap from back to front (or left to right whatever way you see it as).

I will test drive the car more this weekend to see if it fixed it (it was only a 9 mile drive before I had to store it for the week again).

But I started getting misfire codes AKLSALK P030x codes.. Ehh.. Never had them before!

downshift--

I'm having a hard time telling what the last image is...Is it the downpipe/test pipe?

Anyways, it appears as though both sensors are on extenders. Remember, the first sensor is a "HOT" sensor--it's the one that's usually located on the header. This one should NOT be on an extender. The second sensor is the "COLD" sensor (usually located where the cat is) and it SHOULD be on the extender. The whole goal here is to have HOT(temp) > COLD(temp). If they are both equidistant from the same pipe, they are both seeing the same temps. This is probably going to throw O2 codes (or could be the cause of your misfire because of the readings the ECU is getting). Take the front (hot sensors) off the extenders.

Well, after all that, I believe that's what I'm seeing in that last image...I apologize if this isn't the case.

the other day, I drove almost 600 miles on the highway (crusing mostly) with no CEL. the next day, I am goosing it around town and the CEL pops up immediately....P1274 and P1283 (the usual suspects)

Guys just in case I'm wrong (I'm sure I'm not) you guys all have Gs and are getting this code correct? The R&D guys are looking into this now.
