Ok guys, give me your opinion...

I just put on my Berk HFC this past Friday and got a SES light the minute I turned the car on.. odd, but not too weird since I've heard this light comes on for some of us HR owners. Go and check the code but it's not the usual code; it's a 1168 (closed loop bank 2). From what I gather, it's a bad O2 sensor, pre-cat .. you guys think I may have damaged the sensor when I was removing the stock cats? Damn impact tools cause hella vibrations.

What's worse is that my car drove fine until yesterday when all of a sudden, the exhaust sounds different and it feels like my car went into limp mode.. it lurches before taking off when I go WOT.

 

Here's an update.. since I see 32 views but no responses, I'm guessing either nobody knows or nobody's had this issue before.

Talked to Bryan at Berk and it seems my primary O2 sensor bank 2 (driver side pre-cat/header) was damaged during install (if possible, don't use air/impact tools). The ECU therefore could not tell whether or not my car was running rich or lean so it put it into limp mode so that my motor wouldn't get damaged. (This may be why I also had a subsequent P0051 as well). Getting that O2 sensor changed out Monday so all should be well.

 

that's why you should have gone with test pipes. . I have a CEL in my car and no issues whatsoever. I have the technosquare reflash though. But yeah, it seems like the HR throws codes alot easier that the DE. Did you put the o2 sensors back in the bunks? You did not try to clean them or anything cause that would damage them as well.

 

^^the pre-cat sensors never come out during install... the usual codes P0430/0420 are the ones that HR owners complain about and those are the ones that come after the cat. I haven't thrown that code yet and hopefully won't.

 

p0401 and p0402 are the pre-cat o2 sensors iirc...

 

let us know if it fixes it... never heard of impact hurting the 02 sensor, they should be used to the vibrations

you should check the 02 sensor wires maybe you snagged one or something.

 

even a slight drop on the ground and you can damage an 02 sensor. an impact would very likely damage it. i am curious though, how the heck did you get a socket over the end of it with the wires also?

 

they make a special socket with a cut so you can put the wires thru. Personally i use a breaker bar just to be safe. Take it into nissan and get it warrantied! Im sure they will hook it up. There dying for customers right now even if its warranty crap work.

 

um, I'm going to say no on that. p0401 has to do w/exhaust gas recirculation. I don't believe it'll throw the closed loop code.

 

Oh i didnt realize he used an impact on the actual o2 sensor.... Lol. Doubt you can get that o2 warrantied with aftermarket cats installed, unless u are friends with the service manager. Plus, it only pays 2/10ths of an hour warranty time lol... Dealerships arent that slow...

 

are calling yourself a tard?

 

Learn to speak english BEFORE insulting someones intelligence.

 

me, i don't need to know how to speak. I have transcended that speaking process long time ago. I can online-read your thoughts LOL.
BTW the previous post is a joke if you have not noticed.

 

Yes I know.. you say something along those lines after I post anything on here it seems lol..

 

lol, i usually do. DId you get your infectors fixed?

 

nope, i sent them in, they tested and cleaned them but found no problem, but the misfire is back and it is surely the injector because it moves with the injector.....so I get to pull the injector and send it back again! hooray :P

Sorry for threadjack

 

well, good luck mang

 

LOL...we have water sensors ahead of the cats?

 

lulz.. love a good laugh in the morning
