Code P2227 help

[01CobraGuy]

I know Im digging up an old post but maybe someone else has had this issue since, I have the same issue but I am confused because arent the mil elims supposed to send an 'ok' signal to the pcm so it shouldnt even matter if the rear o2's are good or bad?

So you have mil on car?

They can go bad at anytime or could be wrong type..

I took mine off..it gave me codes....

Have you ran it yet without them?..

Ive been called out on mine.had to show video of datalog showing o2s were on and functioning. .I have no cats and no codes..

I do have a Diablo tuner running performance tune with o2s on

You still need properly working rear O2 sensors for the mil to work properly. It doesn't replace the O2 signal, it adjusts it within spec. So a bad O2 will still show a code.

Yes I just got the car about a month ago it has a prochamber on it and a magnaflow catback without cats. It was throwing the cat code so I put the mil elims on it now its throwing a bank 1 stuck lean code

Have you switched mil side to side to see if it follow mil?

Also..pcm is smart..make sure purple plug is passenger and blue drivers..

I havent done that yet, good idea this should tell me whether its a mil problem or if its a sensor problem correct?

Switched mils around and the code followed now coming up stuck lean bank 2 sensor 2, guess I have to go back to LMR and complain about a bogus MIL elim
