SES code 1284
SES code 1284
I searched on this forum and found only one thread that didn't answer my question. I just installed my TN single kit last week and I got a SES light (code 1284 - MAF ) I called turbonetics an was told that it was an O2 sensor issue. I was instructed to move the O2 sensor and relocate it to another O2 sensor plug located lower on the downpipe. Has anyone had this code before??? Any help would be great 
I can't find that code in my list. But if it was a MAF code, why would they say it's a O2 sensor issue? Maybe the MAF needs cleaning or something on the MAF was damaged? Are you sure about the code? Did you actually install the kit?

Went back to the shop again today. We put the car up on the rack and the techs noticed that one of the O2 wiring harnesses was melted (since it was resting against some exhaust piping)... Not sure if this was the problem but they re-wired it and cleaned it up. But they pulled the codes and they got 1284 (again) and a 1273. The code reader said for it to be a "Mass Air Flow malfunction".... Anyone ever get these??? And anyone know a possible solution?
You've already found the thread where these are discussed. I'd recommend doing what turbonetics suggested and swap out the two factory O2 sensors on the downpipe. If the codes switch, then look at getting a new sensor because it's a likely possibility that one is bad (most likely the one that was damaged.
Your shop is telling you it's a MAF issue, when it's not. It's something with the O2 sensors.

Either take these out and switch the holes, or swap the plugs on the harness
If that doesnt work, find out which one was frayed and replace it.
Either way, the codes you're getting shouldn't harm operation. As long as the car is running strong and it is showing acceptible AFR's on an aftermarket wideband or on a dyno graph AFR, then there is really not much to worry about.

Well i even read the code scanner and it gave a general code of "mass air flow malfunction".... But thanks for the good info, as always. I'll try this tonight... How do I know if a sensor has been damaged? And should the shop replace this if it was damaged?

Well, I tried removing the O2 sensors, but they were on there REALLY tight... And the extended pipe for the O2 sensor seemed to be bending from the force of trying to loosen it, so I didn't wanna break the weld... I'll just run it by the shop and have them swap them around and clear the codes again...
Well, the shop ended up switching the location of the O2 sensors... The light went away for about 140 miles, then the SES light came back... I just got me a OBD II scanner, and the codes are still the same (1273 & 1284) What gives??!?!?!
Maybe one of your O2 sensors, or something else, is bad since the harness was fried, not sure. I remember a while back that another guy that fried his harness wiring on piping had the same codes repeatedly.
I'm surprised the shop hasn't given you any more info.

Taurran-- Awww those are my pics from like 2 years ago! hehe.. I took those o2 spacers out.. those are the wrong sensors?
To the OP,
You're screwed. Good luck.
I've spent over 3k in labor/parts trying to fix this the past year since i was dealing with emissions. Finally gave up and just got it "passed" again.
I've replaced all the o2's, harnesses, tore the TN kit apart by 2 different shops, replaced clamps, replaced MAF, regasket exhaust, new plenum, injector harness, spark plugs, Utec, MAP sensor, vacuum lines, you name it, I've probably done it.
I've dealt with Reg over emails and 1 phone call, even offered to help out- nothing really came out of it.
I kind of understand since it's been inconsistent.
Your car is an 04.5/05 right? Seems like it's only those years that have the problem. I haven't seen any 03's with this problem. More common on the G's also.
I remember someone swapped the o2's left and right on the DP and it fixed their problem.. didn't work for me.
Another person claimed it was due to fuel delivery (because it's a lean code).. their CEL's cleared after they installed a CJ RFS. Maybe one of your injectors are faulty?
Another person found a big crack on one of their exhaust pipes which led to the CEL's also.
Here's a quote from someone else when I asked bout the problem also..**I am not trying to start a TN bash/flame thread, so please keep your TN-ego/TN-hating comments out of this thread.
The 1274/1273/1284/1283 codes are common for Nissan's if you have a faulty MAF too. That's probably why your techs recommended the MAF. Most likely not the issue. I pulled my MAF and it was cleaner than the one I was going to put in.
The only other thing you can do is hit up Osirus and get them to hook you up with a CEL flash. I believe GTM does something similar too (they did a CEL delete on a G Sedan TN kit recently) The only downside is they will wipe your TS TN flash, so you will want to get a different management system.. You should anyways.. I couldn't get a hold of Osirus just because they are too far from me and it was a huge hassle to get a dyno and do it over emails.
Let me know if you find a solution. I would be very interested!
Oh and probably want to throw the car on the Dyno just to make sure it's running ok.
I have a bunch of PM's in my inbox from people that have the problem or I've asked bout the problem.. been a big project of mine! These codes are still mysterious.. they are freakish codes that have been very inconsistent amongst TN kits. I dunno if there is a straight answer to this problem.
The only logical (safest $$) solution right now is -- pull TN kit (install Greddy/APS/JWT) Too early to say anything about Plabs or SFR since not many are on the streets.

Basically the two sensors on your exhaust manifolds are reading differently. Normally, the stock ECU compensates by reading the 2nd O2 sensor. But it's getting the same value for both the left and right bank and doesn't know what to do (because one of the manifold sensors is reading too rich and the other is reading too lean). Did you try replacing the front O2 sensors? You could keep trying that till you found a pair that just happened to be calibrated equivalently.

Blaming this on the "kit" doesn't entirely sound logical to me. If what your friend is suggesting is true, it actually appears that it may just be due to variances from car to car and the way the reflash is attempting to adjust AFR's based on expected o2 levels.
The only way I could imagine it being related to the physical kit is if you could adjust the O2 sensor spacers on the downpipe so they were offset *exactly* to suit whatever the ECU is expecting to read from each "exhaust bank". Then again, because of the complete and utter randomness of this issue, it doesn't lead me to believe that it's something that could be eliminated on every single car with the kit installed.
The reason why this only appears on 04.5-05 cars may very well be that they have a difference version of ECU than earlier models. I believe these cars have wideband o2 sensors and maybe it is related to the switchover to closed loop fueling... However, I'm not sure that an Osiris reflash alone could fix the issue with the codes.
If the light is bothering you that much, then you could look at reflashing the ECU back to stock or going with the Osiris reflash, and then installing a UTEC on top of it and tuning. I wouldn't gaurantee this would actually work though.
If this is bothering you that much (although it doesn't really matter in Florida with no emissions tests), then perhaps you should.

Every kit has its pro's and con's.. and basically you're saying that there is a risk with the TN kit of compatibility issues.
People that are looking at FI may not want to risk spending the ~$4900 bucks + install on this kit and getting a light if they need to pass emissions. Whatever the problem is, even if it deals with only the wideband o2 VQ's, they should just go with a different kit? That is a bit of a gamble with 5k+ of money. I definitely lost on this a while ago when I had the kit installed.
Unless they want to spend another 800 bucks for Osirus, 800 bucks for the Utec, and about 250-300 for a tune = 2000 bucks. Wow.. that pushes the price bracket up a bit for more turbo kit options.
The only solutions that have resolved this issue are....
I've spoken with Matt and other people over at Osirus bout the issue, they are VERY HELPFUL and have done CEL reflashes. They are able to do it.. but only if you are local because they would want to tune your car and hook you up with a reflash too. They said they would want to look at the car personally or send them a recent leakdown/dyno so they can make sure it's ok before doing any reflashing.
Sam@GTM has also done some fixes too.

TS and TN have not done anything about it and I don't believe they will. I've had this problem since Nov 06? and have tried to fix it for a while.

Just to let you know I just had a 3" exhaust from the downpipe back. I have pu a little over 100 miles on it and my 1284 and 1273 have yet to return. I don't know if the more restictive exhaust may have been the problem or what. I heading out to go to the beach in a little bit and will put about 700 miles on the car this weekend. I will post back if I get the codes.
