O2 Sensors

[NopWRX]

Had codes P0051 and P0057 (Bank 2 sensors 1 & 2 passenger) come on at the same time after a battery change (with 49,000 miles on the car). I went to 3 different shops and they cannot budge the front bank 2 sensor. Has anyone had trouble with this? Replaced the back bank 2 sensor 2 also and it's still showing a code. Do you guys think it's a relay or some other issue? Thanks in advance.

what tools are they using??? sound like they need to either heat it up to remove the sensor or let it saok in sime pb blaster to get it to budge.

Yea, one of my 02 sensors went bad also, but it was one that was located on the cats. Dealer said it had melted and could not be removed. They had to replace the whole cat. Under warranty of course.

Yeah, they used every tools available at the shop and couldn't remove it. Mine's probably melted too so I probably have to go to the dealer and get it replaced also. Sucks...

BTW, Thanks Dr.2K.. think you hit it right on.

Everything's all good! Deke (super cool dude) from Sewell Infiniti in Dallas got the job done. Replacing exhaust manifold under warranty because of a leak and melted O2 sensor from their 8 year/80,000 mile warranty.
