Charcoal Canister

Hello fellas,

I have a question to ask to those experts out there.

About a two months ago the check engine light came on on my 2005 Taco DC. I took it to the dealership for a check up and was told that the catalytic converters (2) were cracked and the charcoal canister needed to be changed. Apparently, the catalytic converters were cover by the warranty, but not the charcoal canister.

Now the question I have for you guys:
1) is it possible that 2 catalytic converters and the charcoal canister go bad at the same time?
2) where can I find a charcoal canister with out spending $400 that the dealership quoted me?
3) what makes those items go south so quick?

Thanks in advance...

 

ive heard (local news) that if u fill your car/truck up the WHOLE way that it is a good chance u can ruin your charcoal box.like if your pumping and when its full the pump auto shuts off,dont add any more.lady on there was told by dealer that is what caused it.$800 mistake for her.i USED to do it all the time.dont no if that helps but good luck.

 

If I didn't just read your post I would have never believed it, but just this past Monday the auto shutoff at the gas pump didn't work and gas started pooring out of the filler. Wednesday morning the check engine light came on, Wednesday night took it into the dealer and you guessed it, charcoal canister! 51k miles and not covered under the Gold extended warranty. Looking for one myself, so far no luck with Napa or anybody else, factory order only.

 

Dealer said not covered but I called warrnaty co myself and asked, they also told me it's not covered. It's not listed as covered or not-covered in the service agreement booklet I got when I bought the truck. So far all my searches come up with nothing promising.

 

After having replaced the converters, the engine is running smoother and the engine light have not come on anymore in about 3K miles. I was able to find a OEM charcoal canister for $275.00 in a dealership in PR, but since its not "covered" under the warranty I decided to wait and have it check somewhere other than the dealer to make sure it needs to be replace or if it was just a bluff from the service dept. Sorry, but having worked at a dealership for many yrs I dont thrust those guys anymore...

 

Chris, I'm not in California, and that makes ALL the difference. Either you're a TOYO tech and know this to be fact (for instances outside of CA), for which I'd imagine you'd let us know how it's done...OR...you've processed this type of claim yourself and have nothing to hide about how you went about it and I can't imagine why you would not tell the community how to go about it, since we're all on the SAME Tacoma forums trying to help each other out? Or you're only speculating? What is it?

FWpilot...like most the others, my engine is not running abnormal, the diagnosis IS the charcoal canistor, an unless the diagnosis leads to the cat's (covered under warranty) you paid for the replacement out of your own pocket...so what are you trying to contribute? I like yourself do not trust the the service dept's, hence my not spending $600+ to have them do the service and trying to research the fix.

Personally, I'm going to try the cheapest thing first and have the check engine light reset with an empty tank of fuel (as I've found during my searches) and see if it comes on again. IF it does, then I'm going to find an inexpensive OEM replacement and change it out mysef, which i'm more then capable of regardless if it involves removing the bed and/or dropping the tank.

So, unless someone has something 100% concrete known as FACT that there's a way that the EXTENDED warranty or factory will cover the cost to fix the problem...I havent heard or read ANYTHING that leads me to believe Toyota or any of it's extended service providers will do to fix it for no charge.

Has anyone else?

 

If it was me, I would have simply removed the cats, and used an o2 sim for the downstream sensors. They have no effect on the engine performance and simply let the computer know that the cats are functioning properly.

 

Disconnected battery cables yesterday morning to reset the check engine light, tank was close to empty. Light off, filled the tank and drove about 100 miles yesterday and it never came back on, hopefully it won't! Like an idiot, I didn't ask the dealer to reset the light, and of course they didn't offer. $400 for a new canister assembly just to buy it, $600 to have them do the service...resetting the check engine light yourself for free...PRICELESS!
Will keep ya'll updated!

 

Took my truck to the dealer today for a vibration as well as the check engine light, was told I needed a new charcoal canister and they will replace it under warranty. My truck is a 08 with 28k on it, for anyone with a scangauge the code P0000 is what I was getting for this problem.

Im happy they are fixing the canister, they also told me I have a vibration because "I have a lifted truck and they all vibrate". After argueing with them, I just left it alone and will take it to another dealer..

 

I've got 2005 V6 prerunner. CEL was on for over a year with the 5 codes indicating charcoal canister. I finally bought a new canister and filter on line and put them in. I dropped the spare and set the rear wheels on 4X4's. This gave plenty of room to work. Swapped out the parts and had the codes reset. About a week later the same codes returned. Is there something I missed? Thanks for any help.

 

Sorry I cant help, but iv had my charcoal canister replaced 3 times over the years, i dont think iv drove my truck for more then a week without the cel on in over 3yrs.. I gave up trying to fix it.

 

I had CEL's and replaced my charcoal cannister. Problem solved. When I looked at the old CC it appears the diaphragm in the refuelling valve is ruptured. If this happens the vacuum test will generate CEL's. Don't overfill!

 

The 2nd time i had my charcoal canister replaced, i went to the dealer with 1/4 tank, picked it up and returned the next day with it throwing the same code, with just under 1/4 tank, didnt park on any unlevel surface or even opened the gas cap. The dealer replaced it the 3rd time and the code came right back a few days later.. there is a issue with a sensor or something else but the dealer just wont look into it and replaces the canister, i just said f-it at this point..

 

What was the code you were getting?

 

Scan gauge thows p0453 daily, dealer says its a bad charcoal canister everytime i go.

 

P0453 is EVAP system vapor pressure sensor, high voltage input. As I read it's the ECM that biases the sensor so, yup, changing the CC will do nothing. Broken wire or bad connection??? You must have a pretty dumb dealer if he can't figure the code out.

I was getting 455 & 456 indicating leaks. There are probably about 20 emission codes because the system is so fiendishly complex.
