This is a tsb (technical service bulletin, not to be confused with a recall!) to replace the Canister Purge Valve thats located on the left hand side of the intake manifold. Its part of the EVAP system. Mines been clicking loudly non stop at random times for a month or so. I will replace it when I get a chance, so figured I would give people a heads up.
