Hi Im David,, thanks for visiting the site.

To cause a P0443, there has to be a problem with the purge control CIRCUIT, not necessarily the valve. Usually they are a unit housing the valve and the solenoid as an assembly. Or it could be comprised of a separate solenoid with vacuum lines to a purge valve. That said, it could be any of the following: Bad purge solenoid (internal short or open) Wiring harness chafing or rubbing another component causing short or open on control circuit Connector worn, broken or shorted due to water intrusion Driver circuit inside powertrain control module (PCM) is bad

the purge solenoid is in the engine compartment and can be identified from having a green cap on it. you van start the engine and feel the solenoid ticking if its working.
