All three of these Direct Trouble Codes are related. They all deal with the bank 2 Air Fuel Sensor 1 or upstream sensor. By upstream we mean the one before the catalytic converter, or if you you follow the exhaust from the engine to the tailpipe, it's the Air Fuel sensor on top left of the engine. I have included in the diagrams down below factory diagnostic troubleshooting guides for all three DTC's. Please go through these guides and get back to us with what you find out.
