Re: 2015 K2500 Error code: P2097, How do I fix it?

Chances are you have a bad O2 sensor on bank 1. Drivers side before the cat. Sometimes leaky exhaust cause the goofy readings also that throw the code. If it is not rusty looking before the cat and you can't see/feel a leak, then probably change the o2 sensor

Life isn't tied with a bow, but it's still a gift.
Live simply. Love generously. Care deeply. Speak kindly. Leave the rest to God!
It's scary when you start making the same noises as your coffee maker.
