2001 Accent check engine light

I have a 2001 Accent - 1.5L
My check engine light came on and I took the car to a Japanese Car repair
shop that I have been happy with.
I have had the car there about 3 times - they said the code was something
to do with fuel tank leakage of vapors. They have lowered the fuel tank
and replaced the gas cap and checked everything they could think of. Last
week they replaced some kind of a valve called a DM-TL Module (had to get
it from the dealer). 2 days later the check engine light came back on.
(the car always has been running great)

Above was my original post 2 weeks ago.
(the mileage did improve after the DM-TL Module was replaced)

I took the car back today for them to re-check it and they think one of
the oxygen sensors is bad. Part is about $106 from the dealer.
(they don't like the aftermarket non-dealer oxygen sensor) Does this sound
reasonable?? What do you think Hyundaitech?? Are they just throwing parts
at it??

Thanks for any advice!!

 

well ... i think it may be time to learn to work on your own veshicle
cuz if you knew what the error codes were it would be more helpful
(autozone will get them for you for free)

 

It doesn't sound like they're throwing parts at this point. No decent tech
would replace an oxygen sensor to correct an evap code. I suspect you have
some sort of O2 code and the evap problem has been repaired.

 

My husband and I bought an 02 accent about a year ago maybe a year and a half ago. Well this car seemed to be for sale, I believe because the check engine light issue had been a long time issue. All service records were in the car and most places diagnosed the problem to be wires and plugs. I noticed those were replaced at least 2 or 3 times. We also attempted the "fix" we changed them2x as well .... The2nd time my husband did the tune up -i bought the parts. He didn't give me a list. I just bought what i would have assumed needed to be included with a tune up. I got spark plugs, wires,oil,oil filter, air filter, pcv valve, fuel filter, That list sounds about right. Regardless my point is that he refused to replacethe fuel filter and theother valve thing is still in its box. He said that since i bought the fuel filter,(he didn't ask for it) Then i can replace. Well a week after he does his part,(tune up) i watched a you tube video and changed it all by myself. The next day is when the gas light came on.(just low on gas).. Which is the reason for us taking notice that the check engine light was gone. And has been since! I'm happy to suggest you start there.

 

Of coarse this is long overdue of a reply. Sorry just noticed

 

Changing a fuel filter because of an Evap code???
Hardly seems like the right thing to do
However, can't argue with success
I am just thinking that maybe you moved the wires that are associated with the Evap issue
Wait and see ....
