P2A00 SES code
Hey guys,
I ran a search and came up with a few things, but nothing like my situation:
I have an 06 6MT. Mods are: CAI by injen, Berk HFC, powerlab 3/8 spacer and nismo exhaust (on the car for 3 years now). After that it was Osiris tuned by HPLogic in west palm, FL.
The SES light came on after about 300 miles on the tune. It reads this code:
P2A00 Range/Performance, Bank 1 Sensor 1. So the O2 sensor after the headers and before the cat.
I installed the HFC myself, and there are no leaks. After the tech cleared the code at Advanced auto parts, it came back on after 50 miles. I called the tuner, and after searching on the forums, decided that its most probably a bad 02 sensor.
After replacing the 02 sensor, the same code came back after ~300 miles again. I reset the ECU just to make sure, and after another 300 miles or so, it reappeared.
The car feels slightly more sluggish than when the code is not there (It could just be mental tho).
After calling the tuner once again, he said that perhaps there is a bad connection somewhere, or the wiring may be shorted, burnt, etc. This seems unlikely however. He says he can delete the code from being read, but then the o2 would not work properly.
I went to NIssan and they said just to read the SES it would be $95!! damn stealerships! I know what the code is!
Anybody have this problem on an 06 after it was tuned, etc? All advice will be appreciated,

I started getting P2A00 for Bank 2 Sensor 1,just recently. Last thing I had done, was installed Strup headers and a Unichip. Still have my stock cats on, right now, and have an Injen TD exhaust.
Ordered a new O2 sensor from Amazon, and didn't see the code again, after the sensor got here. So I sent it back. Now getting it again, and now getting P2A03...

you should've replaced it anyways.

UPDATE:
Took it to the dealer and had them look it over. He said that there seems to be air coming back into the exhaust and this is causing the o2 to trip. Has anyone heard of this problem before??
There definitely is a performance decrease when the light is on. I find myself having to reset the cpu every couple of days.
Any help would be appreciated

I would recommend starting there in your case as well - searching for a leak. It's the cheapest and easiest to test for. I pray that in both of our cases it's that simple, because I've already spent over $600 trying to figure this one out and have come up with nothing.

I was getting the P2A00... Took my car to the shop and my ART pipes were cracked badly. My car is really low, and the flanges on the Y pipe were huge. So the pipes got welded up and the flanges got ground down at least a qtr inch on the Y pipe. I hope that helps. It was just the Y pipe making contact on the flange. The Art pipes seem to come down closer to the road than others...
The car sounded much better on the way home and felt more powerful even with the CEL on. I reset it when I got home and I dont expect to see the P2A00 anymore...

To onagao,
I read the other thread about the P2A00 gremlin. I went under my car yesterday and checked for leaks (had a friend push with his hand on the gas pedal). As far as I can tell, there are no leaks.
With the SES code on, the car runs different, sounds raspier and gets slightly worse mpg, and performance is worse too.
We reset the code and everybody including me thought that it sounded much cleaner. I don't know what else to do. Could it be a bad cat? I'm thinking of calling up Berk to see if they know something we don't.
Will keep you updated.

Update:
I was jogging my memory of when I first saw the code come up. It was about 3 months after I had installed the cats, and shortly after I installed the Injen Intake and Powerlab Spacer. I never went to get the code checked out because I thought that it was an AFR code. So I dismissed it.
But it came on even after the tune.
Today, I removed the powerlab spacer, and after about 30 miles, the code was back on.
I will be replacing the intake shortly to see if this is the culprit.
I'm beginning to get really annoyed . I don't know what else it could be.

I would recommend trying to replace all four of the exhaust gaskets around the cat section in case there's a pinhole leak that you just can't see or feel. Please keep the updates coming. This is a problem I've been wrestling with for about 8 months now, and I'm going mad.
