Post cat O2 sensor's.
I am having a hard time figuring out how to replace the gray sensor. I can get my wrench on it and loosen it but i don't see a way of removing it and installing a new one easily. This is the post cat sensor.

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. |
