Hi Everyone, I'm using G37 Couoe 2008 model with 138k miles already on it.

Need your help in solving this issue with P2A00 error code. I am up for renewing my registration and get state inspection done but this error is preventing my inspections.
I have reached out to Brakes Plus team for solution and they fleeced $2000 bucks from me for possible solutions interms replacing engine gaskets, spark plugs (for a possible gas leaks) and A/F sensor, etc. But so far nothing could fix this issue.

Brake Plus team's explanation seemed rational in doing these repairs (atleast I thought so) but the issue is still out there and preventing my state Inspection.

I reviewed some other threads in this site for a possible exhaust leak, and I got that checked in my car but seemingly there are no leaks.

I have returned to Brakes Plus team for resolution and waiting their further diagnosis but meanwhile I thought I borrow some suggestions from this Forum here.

Please suggest what should I do. Thanks in advance.

 

According to Google results (did you Google that code?), it's the upstream O2 sensor or sensr circuit on the passenger side.

 

Yes, I did Google it and Brakee Plus team indeed replaced O2 sensor with a new one. Still the code persists..

Check for exhaust leaks. Does it sound any different?

 

I had a similar code but for the drivers side upstream sensor. Turned out to be a cracked catalytic converter weld
