P2A00 appears to be (looking at the service manual here) where a fault is detected in the front (A/F Sensor 1, bank 1) sensor. Possible causes include bad sensor wiring connection, bad sensor, vac leak, fuel pressure, fuel injector.

That's what I've been able to find on it, but I read a few people have had the same issue but not a single one has been able to fix it. If they did, I have found a mention on it.
It started around when I had an exhaust leak after changing the flex pipes out as they were leaking. Seems unrelated though based on the description. Seems like replacing the sensor would be the easiest. Any idea where this sensor is located?
