Went to autzone today to get the codes pulled because my check engine light has been going on and off lately. Its an o2 sensor Bank 2 Sensor 2. I know bank 2 is the bank in front of were the cats would be but it sensor 2 the one on the left or right side of my car? I have the MAC O/R H-pipe but I also have the MIL's on there. I dont think it is the MIL's that are bad because I have 2 MIL's and they are hooked up to both the sensors in bank 1. Neither of the sensors in bank 2 looked bad could it just be a loose connection or something?

you have it backwards. bank 2 is the drivers side bank. sensor 2 is the back sensor. you need to get MIL eliminators or have a tune where the rear O2's are turned off.

I have MIL's on there already. They are on the back 2 sensors, do u think the MIL's went bad or is the wiring not right somehow or the o2 sensor went bad?

dont mean to flame, but you cant read. he said the code is for sensor 2. sensor 2 is the back o2. more than likely changing out the front o2 will only cause his wallet to be $80 lighter. more than likely your MIL eliminator went bad.

Hold the phone here gentlemen. What is the actual code number your car is triggering? P0156? P0430? With the code, I can pinpoint the issue and give you the help needed to get this taken care of. I have some experience in this area...

you should also check if you ripped the wire that goes to theO2 sensor.... found out that was my problem.

I am having the same problem, I have x-pipe and am throwing P0171. System lean bank 1. right now i have nothing on the front senors, and steeda mils on the bank ones. I am wondering if maybe one of my mils is bad. Thanks.

well that code is for the front passengers side sensor. what it says is that you are running lean. the rear 02's would not throw that code.

Most likely your MIL eliminator has gone bad. But, if you tell us the codes, we will be in a better position to give a diagnosis.
