Sonata NF (2006-10) :: 2008 - Engine Management Light Came On
May 21, 2015
I have a Sonata 2008 model which has done only 40K miles so far. All of a sudden i got the engine management light on and i scanned it in the garage. They are saying the fault is with EGR Valve and it needs to be replaced. They reset it and now the light is not ON.
Could it just be a glitch or is it really a problem with EGR valve. I am really confused on what to do, because when i got a second opinion from a local garage they said there is no need to replace - simply a clean would do....
2 days after the engine light reset, when i took the car off the park i suddenly got a grinding noise from the front of the car and i switched if off and re-started and the noise went away..not sure whether this could be linked with EGR valve or was it a simple gear slip.

I have a 2008 Sonata Diesel version, and I am getting the engine management light on. All the times i have scanned it, it says - Insufficient air flow to EGR Valve. This gets automatically reset in a day. Now the weird thing - This is happening only if I drive in and around Heathrow airport I have done 100s of miles elsewhere and this problem never occurs. But if I just drive 20 miles to Heathrow, my engine management light always comes on which resets in a day.
I am really confused on what is happening here.

Earlier today on a easy drive (not pushing it) I noticed a slight "whistle-sound" that I haven't noticed before. About then it became VERY sluggish and the Engine Management Light started to flash.
As soon as I could I pulled over and connected my AL619 and it says "to low turbo/supercharger flow".
I didn't notice any smoke or smell, just a serious lack of power (i was doing 30km/h at the top of the hill).
Just tried to locate the leak, but I cant feel it or see it. I guess one would need one of those "smoke generators" to see where the pressure goes out.
So, do I have a broken turbo, or just a blown turbo pipe/tube?

I've recently rebuilt my toyota celica gt and the engine management light was on , I wiped it and keep getting the same code 52 which I think is the knock sensor car drives terrible under load , idles up and down a little , I've actually replaced the sensor just now and wiped the ecu but as soon as I rev it , bang it's back and I'm getting the same code 52.

Bought a mk4 1.8 gti golf last week and day after I got it I filled it up with petrol at Tesco. Since I did that, the engine management light has been on. It hasn't affected the drive or anything so haven't done anything about it yet.
One of the guys at work plugged in his computer thing to it to find out the fault and the code was coming up as 'cooling system malfunction'. He took the fault off so the light no longer comes on but now it makes the most horrendous noise like a grinder or something when the engine is running. I have not driven it anywhere and won't until it has been looked at but just wondered what others thoughts on it might be? Could the noise be something to do with the turbo? Had new cam belt, water pump etc at about 138000/139000 miles (November 2013) and hasn't done more than 10000 since.

I bought a 2008 Santa Fe last September, since around 2 weeks after I bought it the engine management light has been coming on intermittently. First it then after a few starts it goes off, only to come on again a few days later. Basically dealership hasn't got a clue what's causing it and thus far they've:
Replaced the DPF
Replaced the temp sensors
Replaced injector sleeves
Cleaned the EGR
DPF was changed after they couldn't force regen.
Now, it mainly comes on when I've got cruise control on, although the way I turn it on is bizarre, I have to hold down the on/off and cancel buttons for 10 seconds before it turns on.
Basically I am now running out of solutions as are the dealers, they can't replicate the problem ( although they haven't tried with the cruise)...

I have a problem with my 2004 Santa Fe, 2l diesel. Will try to keep this short!
When driving it suddenly 'heaves' (not sure how else to describe it), then it cuts out. I wait about a minute and then it restarts.
At first there was no 'heave' but there would be a momentary loss of power (I thought it was the clutch). Then it progressed to the 'heave' and then cut out, this happened now and then. Very quickly it started to do it every time I drove it. My neighbor mechanic blew down the fuel line, said the fuel pump in tank sounded ok, seemed to do it more when below quarter of tank.
So I kept tank topped up, it seemed ok, then on one 11 mile journey it did it 3 times, the last time the engine management light came on, crawled it home, after which it would not start at all. The computer said it was either fuel rail or coolant sensor. Neighbor replaced coolant sensor, it started ok. Tried it next day - 6 miles and it heaved and cut out again. This time no light coming on.
I've read about cam sensor, crank shaft sensor, fuel pump at back of engine...

Santa Fe 56 2.2 Diesel ... I am suddenly experiencing the engine management light symbol being illuminated and have severe lack of power I am wondering whether it is Mass air sensor ? blocked fuel filter? or blocked exhaust?

I recently bought a used 2008 Hyundai Sonata Limited. I've been driving it for about 2 weeks now without any problems. I just took it out tonight for a drive and noticed the door open light was on, but not all the way. Non of the doors were open, and when they were the light turn on all the way.
I just turned the car off and the light is still on (dim). What this might be and what I could do to fix it?

I have an 08 2.4L Sonata with 95000mi. When turning the ignition it will crank and sound like its about to start but won't. I was able to get it to start by pushing the gas pedal a bit when it sounds like it wanted to start. Once started, it ran rough and would stall unless I revved it above 1500 RPM. Still sounded like it occasionally miss fired.
I kept it revved until it reached normal operating temp. When I took my foot slowly off the gas, rpm dropped to about 500-600 and it seemed to pulse . I think engine was raising throttle to keep from stalling. It stalls if I try to put in gear without pressing on gas to raise throttle.
The spark plugs were changed at about 70K mikes. I have not read any codes as the car is stuck in the driveway. Could it be a vacuum leak? I know the Entourages have air intake hose leaks that cause rough idle but with a 6 cyl it still runs. Fuel pump problem?

I didn't know my car was low on oil and the oil light never came on. The car has been working flawlessly till I got home and I heard a really weird knocking noise and it's a light knocking noise when the car is idling but when I press the gas pedal the noise becomes louder. The noise sounds like its internal it's coming from behind the engine near the exhaust manifold where the spark plugs are located. I have changed the spark plugs and drained and added new oil into the car but that still didn't fix the issue. The car has about 129,625 miles on it and is in mint condition buying a new engine would be pointless knowing that the value of the new engine is basically the value of buying another used car.

My car is 2008 Sonata GLS 2.4L. Recently the ESC off light turns on always when I drive a while after started the car. It still drives fine. But I have concerns of safety issues.
I heard it's a common issue for Sonata even 2011 model. I also heard Hyundai recalls for a system upgrade because of ESC off light problem. If it's true, will the dealership do it for my 2008 pre-owned Sonata for free?
It drives fine, but anyway it could be an potential safety issue. So should I drive the car to the dealership to have it fixed? I heard may owners spent a lot of time and money but never have it fixed.

2006 sonata gl with 4-cyl engine. Car runs/feels fine. Installed HID kit a while ago (with harness) and no problem. Driving home late afternoon (with AC on hi) stopped on red light. Radio was on but NO HID lights on - then momentarily car stalls. Starts back up right a way and NO check engine light. Tried AC- works fine, turn the lights on (HID 35w slim balast), radio on - everything is fine.
My "suspect" is old battery (original!) and I think that for a short moment charging system (alternator) could not keep up/charge battery while car was idling with AC and radio on (hi load).
How long is original battery good for (5-6-...yrs)? Looked earlier at Everstart batteries (or was it Eveready brand?) made by Johnson. I could only find a few batteries but they were sitting on the shelf since last summer (sticker said made 07/2010 !). Are they any good?

I'm in a bit of a bind. I was very low on gas drove my car on fumes (mistake, yes) back to my place. Today, it will not start. I dumped 3/4 of a gallon into the tank, and still no start.
The ignition will try, fail to engage the engine, and then emit rapid clicks as the interior light flashes. The battery works, as all the cabin lights turn on.
I really don't want to the fuel pump to be broken, so I'm trying to eliminate possibilities before that. Is there something wrong with the ignition, perhaps? What is the clicking after the attempted "heaves" of the ignition switch?

I notice a light ticking noise coming from the front of the engine. It sounds like it's coming from the puppies and not inside the engine. The dealer says it's normal. Is this normal for these cars. Mine is a 2008 v6 With 80k.

I recently got a Sonata from my parents when they moved to Pennsylvania. It's a 2007 with the 2.7 liter engine. It has had low oil for some time, so when I got it (last week) I put more in, up to but not above the full line.
It has had now for just a couple of days a very bad rattle, which is barely audible (but still IS audible) at idle and gets very severe during and after acceleration. It remains for some time even after the gas is no longer being pressed, then subsides a bit. I diagnosed it as knocking, but just today the check engine light came on and the rattle got louder.
I don't have another car to drive and I have class in five hours. Should I drive it or call a cab?

I unplugged the battery and left it over night. Started her up and there was no check engine light. I'm thinking it could be because of the CAI I have installed? Took it to autozone and he said it showing no codes.

I just changed out the spark plugs in my 06 Sonata and now the check engine light is on. The car runs fine but I can't find out why the light is on. Is there some reset switch?

Just went and got my check engine light looked at.
This is what code I'm getting P0174
It's also listing ignition misfire condition
Fuel injector problem
and engine mechanical condition.
I don't know if this is listing probable causes of the P0174 or if it's saying those are also problems.
First time dealing with autozone and there check engine light look up.

My 06 Sonata 120k 3.3L Does not go into reverse. (automatic) Took it for a short (1/4 mile) ride. Shifted fine at first then check engine light came on and it seems to be stuck in 3rd? What this may be, I don't want to get ripped off on a repair I don't need.
