Hi, I wanted to put this out into the forum for anyone having this issue. My 2022 Ct4-Blackwing threw a P0451 EVAP Pressure Sensor Code. Fortunately at this time it was covered under warranty. To fix this you need to pull the fuel tank down as the sensor lives on the top side of the tank.
Part number for this replacement is 13502903. Looks like a standard Acdelco 30-40$ part......but of course this has a lot of labor. Anyways car is fixed and thought this should be out there for anyone in future that needs repair.
