The dealer just cleared two engine codes for me. PO441 - incorrect purge flow
and PO446 - vent control curcuit malfunction
They said they would fix it for $318, just to put in a charcoal cannister. I want to check the cannister and clean it, but I can't locate it. Is it on the driver side of the engine bay?
They want $54 to replace the interior door pull which broke. Guess I'm goin' to the junkyard. I could expect worse from a '98 with 154k.

Also, any ideas if this could be more than just the charcoal cannister?

The canister is right by the fuel tank tucked up next to the rear subframe. Will be quite a pain getting to it - but should be doable.

The codes you posted are most likely the carcoal canister or the VSV that are connected to it. Might be able to get away with just replacing the valves - but it could be a flooded charcoal canister - that will have to be replaced.

I read some instructions in chilton's on cleaning the cannister by forcing compressed air through it. Do you think that would be enough? If it is cracked, I suppose it will have to be replaced.

thanks again, fishexpo101 you're the man!

Sometimes that works - if no liquid is present in the canister. Once liquid hits the activated charcoal in the can, it will be rendered useless. I've eard many stories of people trying to dry them out, replacing the charcoal, etc. - but in the end, they ended up replacing it. You should be able to get one at a much better price than what the dealer is quoting.

Good Luck.

Oh my God, DON'T DO IT! Or if you do, make sure the pressure is real low. I had a charcoal canister explode in my hands while forcing 120psi through it (I was a bit drunk at the time...). Approach with caution.

:lol: lol

Yep, the chilton manual actually gave pressure specifications, which were very low.
The part form the dealer is $222, so I will probably go to a junkyard. I'll let you know how it goes.

The canister is under the rear portion of the car, above the rear muffler.The purge solenoid and canister can be purchased from 1atoyota.com or something like that for alot less monety shipped to your door.
The door pull, (I just replaced,)
can be bought off EBAY for ~$20 shipped. It's a two minute replacement job.

Thanks for the info! I just went to a junkyard for the part.

Door handle - $10
Sunvisor - $15
Seeing the look on the dealers face when i tell them these 'fixed themselves,' - priceless

Here is an update.

I haven't replaced the charcoal cannister. It still drives alright, although it could use a little tuning up. CEL is on most of the time. Occasionally it will go off for a few hours, but then it is right back. Should I bother replacing this? I was thinking of putting in a new O2 sensor. I read in another post about someone havein similar problems, and just replacing the Sensor... is this the O2 sensor?

Ross t. I couldn't find the website you mentioned, but I sent you an email about the parts you have for sale...

I doubt it is the O2 sensor with the OBD-II codes you mentioned earlier. More likely to be one of the VSV valves in the EVAP system (usally runs about $70 a valve). I had EVAP problems early on when I bought My Corolla (bought new - first CEL at ~30K-35K). Dealer didn't do anything when the car was under warranty - even with the EPA ruling in hand for emissions regs and warranty claims - they claimed owner abuse or misuse caused my problems (total BS). Eventually I replaced the cutoff valve on the top of the tank (rubber gasket - $30 shipped), dealer wanted $300 labor + $350 for the vapor canister - even when their own diagnostics could not prove beyond a doubt that it was a bad vapor canister.

About 90K miles later - EVAP problems came back - this time it was a valve. 5K miles later, CEL pointed to a clogged canister - checked it out - was OK, turned out to be a cracked vacuum hose. Just keep at it - you'll eventually run across the problem. Sometimes even wiggling and tightening the rubber hoses under there can make the CEL go away. Most EVAP issue will not kill the car - just cause problems with emissions. If you need to get the car E-checked or smog checked - then you will have to fit it.

I had good luck with the purge valve replacement. Check online if your Corolla is eligable for the extended emission warranty. Contact the EPA if Toyota refuses help and you're within the criteria for the extended warranty.

Would a defective charcoal canister cause a foul exhaust odor or would this most likely be the 02 sensor that has 130K? I recently posted an inquiry with a p0420 code and replaced the CAT. I sure am learning alot from this forum and appreciate the knowledge. With 130K miles I may be a regular visitor.

Thanks

So the door handle is also known as a door pull? I have replaced most of mine, but for some reason the model years are not all the same. I have posted another thread in this forum about me getting the wrong inside door handles from a junkyard. They looked identical but I found out that the 1993 - 1997's do not all use the same one as I was under the wrong impression. I paid $5 for the inside ones and $11 for the outside. Anyone want to purchase them from me?

[Anton]

Well, Thanks for the info. I looked into the Extended emissions warranty. I spoke with Toyota customer service. They said I was beyond the warranty period. Well, there is 162k mi on the beast, so I can understand that. I think I will look into the purge valve replacement.

high tidings,
Anton

You could try the junkyards again. Just replace the charcoal cannister. It is probably cheaper for you to do it than to have it done by the dealer.
