I have a 2005 Mustang GT and find the Mustang forums a great help when searching for information, so I thought I'd give this forum a shot. My Wife has a 2002 Sonata V6 (which we like so much we plan on passing it down to my Daughter this spring) and she's been having trouble filling the tank lately (with a CEL light). We've put over $3,400 into the car over the last two months doing maintenance and fixing the A/C system, so I'm looking for a low cost solution. Now, modern Mustangs (and many other cars from what I'm finding), are notorious for the same problem with filling the tank. I'm finding it's related to the vapor recovery system, in particular the filter for the gas tank. It seams the filter gets clogged and triggers the pump to shut off. My research here seems to indicate similar problems to my wife's Sonata. I'm looking to double check the location of the filter canister. I think it is located behind the driver's side rear wheel. Do I have to remove the wheel well liner? Or is it located elsewhere? I have to admit, I haven't put my head under the car yet, but any light you could send my way would be appreciated.

 

This is the thread you'll want to read:

FYI, here are diagrams of the 2002 Sonata system:

 

That's exactly what I needed. Thanks. I knew somebody would have the answers I was looking for.

 

What code you got ??

Here is a P-0446 last week or so on an EF Sonata -

Pics are of the old canister,,, hoses all moved to new parts..

Replace the canister, canister close valve, and filter as a package deal.. dont want to have to take it down in couples days and replace another part.

 

As I mentioned before, I haven't actually put my head under the car yet. I'm still trying to gather information. Were the parts you changed out easily accessible to someone with a floor jack and stands? How much did the parts cost and where did you order them through?
I have a tuner for my Mustang that reads codes (Ford vehicles only) but not Hyundai. My Wife gets home after dark, so I haven't had a chance to run the car down to the corner shop so they could run the code for me.
Given my experience on other vehicles and what I've been able to research regarding the Sonata, I'm assuming (gosh I hate that word) that the CEL is related to the slow fill issue or more directly the vapor recovery system.
Your point on replacing the package makes sense. Thanks.

 

Get down to Auto-Zone or Advanced before they close and get a free scan.. make sure you write down the full "P-xxxx" code(s)... I dont need the misc jibberish associated with them.. I know all that from working with them

 

The error codes were standardize under OBD-II, but the communication protocols have somewhat proliferated. I understand the protocols even differ between Hyundai and Kia products. Some scanners are very limited with the number of manufacturers they work with. I recently purchased a OBDPro ELM327 scanner that was suppose to be the closest thing to a "universal" scantool, but it came with an list of new protocols (mostly high end models) that it will not work with.
