If I have them turned off, what would happen?
I still have the cats, but I am running with the cutouts open.
I am also running with no egr.
do I need to make sure that all diagnostic tests are off for the EGR, if the main is turned off, and also what bank is the rear O2's, I was thinking they where bank2. so if I was to turn them off then anything with bank 2 would need to be toggled off correct?
just currious,
thanks,
Daniel

 

The rear O2's are B1S2 and B2S2. Each one has 4 codes that need to be turned off and you'll be set on that. Turning them off won't cause any problems. Mine have been turned off for a long time now. I even passed the computer plug in "emissions" test with them turned off.

Not sure on the EGR question. Just turn off all EGR related codes to be sure.

The rear O2's are Sensor 2 on both banks. Bank 1 is the drivers side and Bank 2 is the passenger side.

B1S1 = Driver side front O2
B1S2 = Driver side rear O2
B2S1 = Passenger side front O2
B2S2 = Passenger side rear O2

 

ok thats what I thought.
I had allen turn them off, and I was going thru my file and noticed that they where all on again.
I couldnt remember what bank, or sensor it was.
I have all of the egr turned off, cause I removed certain items from the truck., so I know I am set on that.
Thanks for the info
