99 Camry fault codes

I have a CamryV6 with 100k miles and the check engine light is on steady and took it to AZ and the codes are P0441 Purge flow and P0306 #6 misfire. How do I reset these codes and what do I do about them? The engine runs fine, I can not detect a misfire, its very smooth. Someone suggested that the 441 code could be related to the gas cap! thnx

To reset the code, pull the ECM fuse (driver side, engine compartment fuse box) for 1 minute.

P0441 Purge flow problem is usually caused by the purge solenoid. The V6's is under the plastic noise plate on top of the engine. I'd check it by removing the EVAP line coming from the canister at the solenoid and listen to the port while the engine runs. It should switch on repeatedly and you'll hear loud vacuum sounds (near full engine vacuum, not the wimpy 3-5 PSI vacuum you get with a stuck solenoid). If it sounds weak then you know the source of the problem. Take necessary precaution with the EVAP line as it has fuel vapor.

Cap usually sets another code, I think the 0446 because the tank doesn't keep pressure and the problem will go away if you retighten the cap. If not, and if it's the solenoid it'll come back repeatedly and often, then you can try cleaning it by prying open the metal tabs carefully. Or you can buy a new solenoid. But isolate the problem first. If it's not the cap or the solenoid, it may be a bad canister, common in those years. $$$$$

P0306 Did you have a tuneup lately? Bad spark plug or wire for starters. Less likely injector or cylinder/valve problems as you said the engine runs fine.

Thanks for responding John. Is there a picture or diagram with parts ID somewhere on the internet so I can trace this problem. These parts are hard to Id under the hood ..thnx, Paul

Hayenes manual is probably the easiest place. AutoZone's free online guide goes up only to 1996 for now and the canister is in the engine compartment then.

VSV can be bought online at a dealer in Texas for 1/3 less (do a search on previous postings). But local parts store may carry it, not sure because never needed a new one besides cleaning it carefully. But if it's the canister, dealer only, $$$$$.

If it's the bad batch of canisters and it is blowing carbon dust, then all EVAP hoses will have to be replaced, probably all the VSVs too to rid the dust.

Your car may be covered under an extended court ordererd ruling against Toyota. Anything to do with the gas evaporator emmisions system is covered on vehicles 1996 to 1999 with less than 150k. If I can find the literature I collected when my wifes 97 had that problem I will send it to you. If you do a yahoo search for Camry emissions lawsuit you will be on the right track.
