P2631 - Part number for A/F sensor
I have an 03 Accord V6 that is giving me a P2631 code - Front Air/Fuel Ratio (A/F) Sensor (Bank 2, Sensor 1) LABEL Circuit High Voltage. I would just like to replace this sensor, but I'm having a hard time figuring out what the right part to buy for this would be. Does anyone have a part number to replace this sensor?

Why not call a dealer and ask the parts people? Are you sure it is a bad sensor? IT coild be a broken wire the comp sends out a ref voltage and does not like what is comeing back With out a FSM and test tools you might want to go to a good driveabilty tech and pay for some diag. time IMHP

Yeah, you need to diagnose before just throwing a $120 sensor at it.
At least figure out which bank is bank 2 and check wires/connections.
It'll be number 9 or 19: http://www.hondapartscheap.com/find-...OLD%20%28V6%29

Your V6 has 2 air fuel ratio sensors and 2 secondary oxygen sensors. The air fuel ratio sensors are the same part number, Honda part # 36531-RCA-A02. See attached picture for location, in front of car with hood opened.
