The 'Check Engine' Light does not turn off?
I have read every discussion on this page and thankfully my sonata runs good based on the reviews i read. the car is a well taken care of car but the check engine light stays on. it has been about 6 days and the light does not turn off. the engine and the fuse box are doing well. everything else is doing well. have had friends that work with vehicles and they say they do not know. i need an answer. my last place to go is to a dealership.
No one can help until you get someone to pull the codes the computer is reading in order for it to put the check engine light on.
Check the gas cap it is a common cause of the check engine light problem.
STOP using ethenol gas it causes poorer gas milage and resluts in the check engine light coming on. After two tank fulls of PURE gas ( non Ethenol ) the light went off!
Take it to the dealer. My 2011 elantra has been in 4 times for the check engine light. Thy replaced the o2 sensors, but the light still comes on. Hyundai corp is flyin in a tech, because they are apparently having widespread problems, primarily on the east coast. Dealer tried to tell me it was bad gas in the region, but I think that's a load of doodoo. Take it in.. Emissions system is warranted for 8 urs 80,000 miles!
Just have the codes read at autizone or something. The check engine light neans the computer thinks something is wrong. About 50% of codes do not create a driveability issue but is emissions control related.
FYI, I had the same problem (Sonata 2009) and had a dealer check it. They pulled the code, told me it was an evaporative system problem, and asked about refueling and the fuel cap. They reassured me, as I was in the middle of a nearly 3000 mile drive, that it wasn't critical. So, here's the thing. We were at around 6000 feet above sea level, in New Mexico. When we got to the Bay Area in San Francisco a few days later, guess what - the light went out on its own. Which suggests to me that it was to do with altitude and the changes in atmospheric pressure, and actually nothing was wrong at all.
