Get the anti fouler from Ebay, put it in and clear the code. Simple as that. It's your cheapest solution and most likely your problem.

When you've done that, then come back and fill us in

 

Not true... .it is definitely bank 2

 

Nope, that would be bank 1, sensor 2.

A V style engine has 2 banks. In a V8, the side with cylinders 1,3,5,7 would be bank one, 2,4,6,8, would be bank two.

 

+1 to this. I had the same problem after installing a High Flow CAT, I followed the above thread using two anti-foulers. Did the trick for me, I never saw the light again, and it passes inspection via OBD II too.

 

I contend it is bank 2....

 

After getting a degree in automotive technologly, and becoming a certified technician for Cadillac/GM I would hope I knew what a bank of cylinders was.

At any rate, getting the O2 sensor out of the exhaust flow will cure the problem.

 

^ All of this

I thought the bank 2 thing sounded strange. The anti-fouler trick worked for me, so is probably the cheapest option.

 

sweet, im going to try the mechanical fix during the weekend. the cel has on since i bought the car 7 months ago.

 

a bank of what????

Sarcasm -> look it up

 

any knowledgeable tuner will be able to eliminate the ses light without having to install an anti-foulers, o2 sim, ext bung etc......

 

You can also set up the ECU to pass all OBD2 tests if you want to. But the anti fouler trick works, anyone can do it, and it will only cost you $5.
