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

Re: 99 Camry fault codes

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.

Re: 99 Camry fault codes

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

Re: 99 Camry fault codes

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.

Re: 99 Camry fault codes

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.
