So my service engine soon light came on and a used a reader to pull the code. It read P2A00 O2 Sensor Circuit Range Performance Bank 1 Sensor 1. I cleared the code to see how long it would pop up again and it took about 1 week and a half. All I have is an R2C intake and Tanabe axle back. What do I need to do to fix this issue?

 

im curious to know if this problem has ever been resolved. i kno its not my O2's but have no clue where to go from there. i have motordyne art test pipes with ark grip cat back. my first car had the same set up on it and no issues. put the parts on my current car and about 3 months later i am also getting this P2A00 malarky.
