Hey how are you guys! Im really new to this cars. Just picked up a 08 350z about 3 weeks ago traded my 08 civic SI. About 400 miles in my SEL turned on and got it scanned and its a P2A03 which is Bank 2 Sensor 1. So I did read some threads about the code and nobody or atleast not that I read fix this issue yet.

Heres what I did so far. I plugged it my friends computer/scanner to check the volt readings on my sensors and both bank 1 and 2 sensors are similar range. So now Im thinking my sensors might not be bad after all. Also I checked for some exhaust leak and I cant find any leak. BTW It has a new Nvidia Gemini exhaust. I tried deleting the code about 3 times and it always comes back after around 40-80 miles. I really dont wanna take it to shop (BUDGET ISSUES LOL)

I just wanna see if theres ppl that actually had this problem before. I wanna know where to start. CAR RUNS FINE! its just that P2A03 code.

THANKS IN ADVANCE YALL!!
