Need some serious help. 2001 MONTERO SPORT O2 SENSOR, BANK 2 SENSOR 2 IS GOING BAD. WHERE DO I LOCATE THE SENSOR AT? CAN I FIX IT MYSELF? HAVE HAD FOR 2 YEARS NOW AND BEEN TO MEDINA MITSUBISH 6 TIMS NOW AND THEY REALLY HAVE RIPPED ME OFF, JUST HAD A COMPLETE TUNE UP AND THEY DIDN'T TELL ME THAT I HAD A HEAD GASKET LEAK.

 

Welcome to the site!

 

thank you

 

welcome

 

well as far as i know with most cars the sensors are located on your exhaust piping ussually one after and one before the cat. I am not totally sure with your car having never seen ti before, but my guess is that since its bank 2 then its most likely the one after the cat. You should be able to get the part from autozone for pretty cheap. I know mine wasnt that bad. Then i was able to get it installed for only $35 at a shop. I is ussually easy to do as long as there is not alot of rust. Mine had so much rust on it to the piping that i decided to just have a shop do it and save me the aggrevation.

 

o2 sensors are always in the exhaust at some poin like said before one before and one after tha CAT.


BTW welcome to the Forums
