THIS O2 SENSOR STUFF can be perplexing. So far eneded up replacing b1 1. and b2 . Replaced all coils and plug on 78000 mile g37 .... appreciate your efforts.. sincerely John
I appreciate the comment and watching. I just ordered 4 new O² sensors to see if I can see an immediate difference in readings between them. Video to come soon. Let me know if you still have the codes popping up. I'm more than happy to help you solve that issue.
I am currently having the same issue, at first it was on my bank 2 driver side (P2A03). I swap the o2 sensor to passenger side bank 1 to see if the code travels, which if does, it indicates bad sensor. The code indeed travel to Bank 1. I purchased new sensor from amazon, replaced the bank 1 sensor and the code persist. I might have to get denso oem, but shit is pricey af.
I completely agree these sensors are NoT cheap! I'm dropping a new video tonight on Part 2 to finding the issue. It is very smart and a good practice to move the sensor and see if the issue follows. Thanks for watching and commenting!
Did you finally fix it. I was going to say I hear that an O2 relearn is required after a fix. You can google the relearn procedure. Has to do with the maf sensor reset.
@@DarrelllCampbelll you can easily relearn by disconnecting and reconnecting battery. What you're referring to is the "pedal dance" usually use after replacing ur intakes, tb, maf
Hello. If you think no leaks exist anymore, you can try the MAF sensor reset that relearns the air flow ratio between banks. The new video up tonight has a clip with the process written out. Please LMK if that helps as I'm trying to figure out this very indirect trouble code as well.
I have code p0138 and code p2a00 so basically the passenger side saying both sensors are not reading correct I think it’s a leak because I just installed test pipes I used copper gasket maker I might not of torqued the bolts enough
Go back up under and have a lightly wet hand. It helps feel for air leaks when running. Do you have the correct O² sensor extensions installed? They need those spacers when test pipes are added. Easiest on your pockets to check for air leaks. Next would be to test the O² sensors IMHO. I hope that helps. Best of luck. That P2A00 tends to a leak near 0² sensors and intake system after MAF... if that makes sense😅
@@Everyday_Trey I need to get the extensions the berk resonated test pipe kinda have one but not enough I wonder if my 02 sensor is actually bad or if it’s a leak I’ll have to look

Good looking out!! Solved my issue!
I am Super happy this helped solve your issue. Thank you for taking the time to watch and reply as well!

The problem was leaking cat/testpipes which cause the code. Either replace them or put the o2 bung extension.
No I had same problem and my problem was Amazon sold me a faulty one i replaced that and problem solved
I have a p2A03 code just put in z1 test pipes checked for leaks fixed leaks checked 02s replaced 02s what should I do next
