Hi Billmcc64,

Guess you haven't been searching on-line much! Lot's of Toyota owner think there should be a recall, and that Toyota is stonewalling. Seems many, many Toyota Carbon Canister systems fail for various reasons. This seems especially for pre-03 models (after which they relocated the Canister to higher level than gas tank). With all the valves and road-debris back above rear axle-beam, no wonder dirt and water can effect the numerous hose connections and valves.

Anyway, yes OBD codes P0440, P0441, P0446 can all mean dealer replacement of the Carbon Canister. Going rate right now appears $265 for part and another $140 for Labor (if they charge the customary half-hr for OBD analysis). It's a crap shot if they really spot the cause or just know from experience that the Carbon Canister is problematic and replacing usually cures CEL. BTW, I also wasted $8 on new gas cap; that really is sucker move (but everyone feels obliged).

PS - My OBD readout for 2000 Corolla was only P0446, and yes, the replacement of Carbon Canister (which comes with two VSV) did make the CEL stay away. Cost at Dealer was $411 total.

Just try to minimize damage and don't thank Toyota for their premature failed system.

Newer not always better!!
