Code P0451 EVAP (Mazda5)

I have the same code and replaced all the sensors but it still comes on. Runs poorly and stalls out after I fill it up with gas. I’ve been throwing parts at it for over a month to no avail.

Did you replace both
CG36-42-580A...........Evaporation hose assembly with FTP sensor MSRP $ 227.88
CG36-42-580A - Hose, evaporation. Engine, fuel, tank, transmission - Genuine Mazda Part

L5E1-18-791A............. Short cord MSRP $ 52.39
L5E1-18-791A - Cord, short. Engine, fuel, tank, transmission - Genuine Mazda Part

I only replaced the sensors no hoses.

When you get the code there is stuff in the hose. The new hose doesn't allow stuff to keep getting on the sensor. See report. Mazda Pressure
