Just hit the clear button and your good.

 

haha ive done it a couple times it keeps coming back.

 

Trey I had the same code was caused from gasket failure on my pipe bomb I used the ones supplied with the pipe bomb and the were shot when I removed and sold it 2 months ago went back to OEM y and new OEM gaskets haven't had the code since

 

do you know if it was the gasket that connected the y pipe to the headers or the y pipe to the exit pipe with muffler

 

It was the ones from header to ypipe

 

oh I doubt it was that, i havent touched those.

 

Try swapping both rear o2 and see if it trips again on the same side or if it goes to bank1

 

dont make fun of me but the largest metric open end wrench i have is 17 and this is a 18 or 19. Im a bad mechanic lol. I guess im going to sears tomorrow. This wont hurt anything by driving on it will it?

 

Dude I had the same issue had to borrow a adjustable crescent to swap mine out when I put in the pipebomb so I have no room to make fun. I don't think any harm will come I drove mine for 5 or 6 months and had to clear the code 5 or6 times. If it throws a p0152 then you will know the sensor is bad but if it throws the same code I would look into an exhaust leak somewhere

 

yeah i thought about the crescent but i just dont want to fuck it up.

 

Keep me posted with your findings

 

Ok i got board and ended up getting them both off with a 7/8th wrench, but on the drivers side the rear has a longer cable so they couldnt be interchanged. the short passanger side couldnt reach the other side. so what I did after was I unpluged the passagner harness and started the truck and threw the same code. So this leads me to believe that my passanger side 02 sensor is bad.

 

I found replacement OEM ones here

Sorry man I didn't know about the cables when I was troubleshooting mine someone on xru told me to try that but I never got around to item

 

dont worry about it at least now I know how to take them out and put them back in.

 

wait does anybody know what bank 2 sensor 2 means. or its location?
