The 443 is the EVAP 'control system' 'canister purge valve circuit' open or a short to v-pwr.
Check over the harness and plugs for damage, rub-thru etc.
Don't replace parts until you prove they are needed.
The PCM does the testing and detects the fault.
What was important here was you replaced parts without knowing what the PCM detected as the fault.
Good luck.
