2004 Hyundai Accent Check Engine Light

2004 Hyundai Accent, 4cyl, 90K mi

Check engine light came on back in December 07. Went to Autozone & dont remember the code but it didn't make sense, said my car was a Mazda and they said take it for a full diagnostic. My battery died shortly after, replaced, light went off (Im assuming now since it reset the computer). Month or 2 later it came back on & I did nothing. Now my car is way pass due for inspection in Texas. Car runs fine.

Went back 2 autozone yesterday, code was P2407 EVAP leak detection pump sense circuit intermittent. Saying it was a Mazda again and I think the same code from a year ago. Took it to a shop for full diagnostic, didnt get the codes or remember explanation exactly but said it was something to do with emissions and plug misfiring ($200 tune up would take care of that apparently). The other code (emission) was going to be $800-1000 for the part alone, and no guarantee that would do it. So instead, he cleared the light & Im waiting to take it in to an inspection place and see if it will pass. I know car computer has to complete cycle, but not sure how long I should wait. (Drove at least 30 miles highway, 20 min stop & go, 6-8 times turning off & on, & 5-10 min idle and no light yet). What do you think I should do? Any help would be appreciative!

Evap leak codes are normally a hose that has split somewhere allowing a vacuum leak, or the gas cap not turned tightly when filling with gas.

The other problem is hard to determine without the code, or a description of the part that need's replacing.

If you can provide more information about the $800 problem, we can provide more advice on what to do.

Attempt to get your inspection now, as long as your emmissions are within the acceptable limits, you should pass

P0441 code evap for Hyundai Accent 2004


You can clear the code and see if it comes back first.
Code 441 is for incorrect purge flow which means the computer vented the gas tank to the vapor canister and the flow went the wrong direction or there was a vac when there should not have been.
If the code returns a mechanic will need to check the gas tank vent.

A blinking check engine light indicates one or more cylinders is currently missfiring. You will have to scan the computer and get the code to determine which cylinder it was. Then you can start you diagnostics to figure out why it was missfiring.

Check the O2 and mass air intake sensors. My girlfriend was having the same problem and not able to pass emissions. I forgot the codes. It will cost ALOT less if you can do it yourself. Relatively simple repair.
