how many rear o2 sensors are there in the rear? supposly the exhaust shop installed the bbk mil elims(1pair). reason why im asking is bcuz 10 minutes from exhaust shop i got a CEL and i was like wtf. So a few days later i went to autozone to see wut it is, and its throwing code p0161, finding out its a malfunction in the heater circuit for oxygen sensor 2 in bank 2 going by what the PCM read. im takin a guess i need 1 more pair? if i do need 1 more pair can the mil elims still be installed without redoin the rear part of exhaust?

there are only 2 o2 sensors in the rear and 2 up front. mil eliminators dont always work. if you wamnt a surefire way to fix it, buy a flash tuner and remove the error codes for rear sensors

EDIT: HMUSN=quicker than me

^ always man.. always.


there are 2 types of mils.

the ones AB posted below and a type that you have to splice to get to work.

well you can plug in the MIL eliminators yourself in less than 10 seconds for each one. your rear oxygen sensor plugs into the bung in the midpipe, then you plug the electrical end to the MIL eliminator harness which plugs into the main harness near the middle of the underbody. it is a simple electrical plug:

if your MILs don't work there is something else that works pretty well. Buy a pack of anitfouler from autozone. take one of them and drill it out with a 1/2in bit then screw one of the antifoulers into the one you drilled out then screw the o2 sensor into that setup and screw it all into the O2 sensor bung. What it does is catches a small bit of exhaust for the o2 sensor to read then the higher pressure flowing exhaust gas goes past without the o2 sensor reading it.
