Sorry if this is a wrong section. I thought DIY will be the best place to ask.

Also these codes (2C7B) are not normal DP codes that we get. This is a bad sensor. After talking to a few people they said that both post cat O2's can be removed W/O removing the DP's. I got to one but second one seems hard to reach. Maybe its the way my DP's are positioned.
