Hi everyone, I decided to come here as my last resort for a CEL fix for my wifes 2009 Honda Pilot. Recently replaced both cats and bank 2 sensor 1 02 sensor being that was the only code present after replacing the cats from a P0420. Ran fine for a few weeks with no CEL, now I have a P0135, P0155 and P0498 codes that are persistant and will NOT clear, regardless of disconnecting battery or using a Actron diagnostics code reader. Ive checked the ACG fuse on the drivers side fuse panel and all checked out. Im not sure I there is a designated relay for it, as I was not able to locate it. Anyone have any ideas befor I replace the Bank 1 sensor 1 sensor? My only guess is perhaps the sensor shorted to ground that's causing the other 2 codes to be persistant. Any help is appreciated, thanks in advance!
