High fuel pressure?
I have a code p0451 with a p0446 code that I知 completely stuck on. I replaced the fuel pressure regulator with an oem one, oem fuel pressure sensor, pvc valve, and evap canister but I have no idea why I still have this code. I知 super stuck and idk where else to look for a next step. Anybody can help? Tubes are all good and idk if the vent valve is what痴 wrong. Where would the vent valve be?

Both are evap codes. My guess is, evap pressure sensor, or maybe a crack in a evap line causing evap pressure sensor to not read correctly. I don't think fuel pressure has anything to do with it.
I think Techstream hookup to odb-II port has menu to activate or test the evap controls.
If you don't have Techstream and dongle to do it, maybe a dealer (or friend or import shop) can at least diag it for you, then you fix it.
