My '01 is throwing a P0441 code (evap emission control system purge flow fault). I replaced the NLVD (natural vac leak detection assembly) and made sure that the gas cap was tight. I also scanned for damaged hoses underneath the van. Unless I missed something, that leaves the charcoal canister or the Purge Solenoid as the last components to inspect with this system. Anyone know where these are or how to inspect, or deal with this code?
Here's a link that helped somewhat:
