Elantra HD (2006-10) :: Check Engine Light Never Turns On
Aug 16, 2012
So I have an issue with my 2004 Elantra GT. I failed inspection because my CEL never turns on. Even when first starting the car. I originally had thought the bulb was burnt out, but it started working fine on its own a couple weeks ago. Then 2 days ago, it stopped working again. So, where should I start in finding the problem? I had a radio installed a couple of years ago, and I have had issues since. Like, my odometer button no longer works, and the radio will occasionally reset when I start the car. So maybe I should remove the dash fascia and see if there are any loose or unplugged wires?

Our second car is a 2007 Accent, 125KM's (70 miles). Today the engine light came on, I drove it very slowly to my indy mechanic and she is not throwing any codes. Engine temp was fine and she just had an oil change.
Engine light turned itself off so I drive it home and on the way it's all good then suddenly .... she dies. She starts again and I get home, i idle in the driveway and she stays on but a little rough as she is sitting at 800RPM, is this right or a little low?

I just completed my move from Pennsylvania to Denver CO, and my check engine light is lit up (orange) today. It wasn't on for the drive, but came on this morning when I started the car, after a few days in the parking spot.
I heard it might be a gas tank pressure thing, but the light is still on after filling up today. I'm sure it's a result of the thinner air up here, but should I be worried? Does this warrant a trip to a dealership? Or should I just stick it out until my next oil change (in maybe a month or so)?

My check engine light popped up the other day and when ran, 3 codes popped up: p2414, p2195, and p0170. From what I could gather it looks to be the O2 sensor is bad. This would be the one on the exhaust manifold, correct?
Also, what would cause the o2 sensor to go bad in the first place? My 09' has roughly 65k miles.

I have a 2005 passat 1.8T non 4-motion and the check engine light turns on with no noticeable performance loss or idle fluctuation then will turn off in 3-4 days only to turn back on in another 3-4 days. My guess is something with the fuel, or moisture in the tank or even a stupid gas cap problem but im just shooting my question out there hoping another passat driver has experienced this same ridiculous problem.

I have a Toyota camry 2004. My engine check lights goes on and automatically turns off after some time. There is no specific pattern on when it goes on or off. I got it checked for the OBD codes and both the times the mechanic said the codes read a bad O2 sensor on Bank 1.
If the O2 sensor is really bad isn't the light supposed to be on all the time. I wonder it might be something else that is turning my engine lights on.

So I start my car up a day ago and the check engine light turns on. So my dad and I plugged in our computer and it flips car code P3081. I did another search on google and a mk4 site popped up and said something about not reaching operating temp. So i guess my question is what would cause this to go off?

I have a Honda Accord that has a very strange kind of failure. I've taken it to two mechanics - both fixed "something" - but I'm still without a car.
99 Honda Accord LX202,019 Miles
My check engine light is on and one time while driving down the road my car turns off. I need to make a road trip so I go see Mechanic 1.
Mechanic 1 - Check engine light had been on and his machine tells him the O2 sensors need to be replaced. We replace both. Light goes off. When asked about the 'spontaneous shutoff' - said it was a fluke and probably no big deal. He can't see anything other than what the computer tells him to replace.
Instrument panel currently shows no lights on. Everything works normally. I drive 1500 miles back to Wi and right as I get there....
Case 1 - I am driving down the street (residential, freeway, whatever) going any speed and the instrument panel suddenly loses all power. Speedometer drops to 0. Odometer drops to 0. The cabin (radio, clock) remain on and undisturbed. Engine is completely unresponsive to depressing the pedal and seems to be completely disengaged. The car is hard to steer but can be angled off the road. (but you can still hear your music....hooray...as you try to not get killed dodging off the side of the road)
Case 2 - On the side of the road/parking lot and the car will not turn on. Seems like it is about to start, but then dies before completing turning over. You wait 15 minutes. Then the car will actually turn over a bit more, but still not complete a start.
Case 3 - As I start the car I press the gas and rev the engine up to 4K RPMs for 4 seconds. The car then remains on. I drive for as long as it will go before Case 1 happens again.
While in WI I take it to a mechanic 2.
Mechanic 2 - Runs a test and believes there is a failure in the ignition assembly. Replaces 1 part that spans 3 different parts because he believes its cheaper to do that than to have him go all the way in there to get the 1 that he thinks is bad.
I drive the car 1400 back to AZ and Case 2 happens when we stop to get supplies. I perform case 3, the car starts and we make it back to California alive.
I try to drive the car around locally after getting back but cases 1-3 happen every other time I drive it.
Case X - The car sat idle for a few weeks as I thought it was "not safe to drive." Power locks on the car start to fail. No longer can get into the car without putting a key in a door and only that door will open. Car now has no power.

I own a 2000 Ford F-250 5.4 Automatic. It tows my 5th wheel trailer very good. On our last trip it suddenly experienced the "check engine light" effect.
The light turns on randomly and either goes of after a couple of seconds or it doesn't go on when I restart the engine.It is mainly annoying, but when in towing it really hurts, because the engine switches into an emergency mode and stalls.
I read that the engine uses only 4 cylinders. I read many articles on the web about that light, but I couldn't find a solution. The thing is I brought the car to several repair shops but none read a code from the computer.
I think it's not a real fault but a misreading or maybe a cable that's grounding? The problem is, I can't bring the car to a repair shop, because there is nothing wrong with the car. How can I find the source of the problem?

On my 2002 F250 7.3 I kept getting a check engine light when I pulled my 5th wheel uphill, I took it to a shop and they told me my HPOP needed replaced. I bought a new pump and installed it. Now my check engine light comes on and turns off during normal driving conditions. I do not have a code yet but hoping there is some idea on what might have happened.

A few days ago my "Check VSC" warning came on along with the check engine and traction lights being on. I left my car in a parking garage for a week when I was on vacation and the lights came on once I started the car after getting back from my trip.
I have had the "Check VSC" warning before and I fixed it by replacing my gas cap. My gas cap seems fine this time around so I got my codes scanned and the only one that came up was P0300. Having this issue with the 2007 Lexus GS 350? I still feel like it's my gas cap because I bought a cheap replacement last time around.

While I am driving the car it will start to die and skip. Happens randomly. Today I was driving up a small hill and it went quits on me started lurching with check engine light coming on and off. The car will turn over and start, but only for a few seconds before dying again.
Seems to happen when the car is running for a while. Also the ABS light flashes on then off randomly while driving sometimes although It hasn't been an issue. Will be checking tomorrow to see if it starts.

I'm due to leave at 6am sharp on Friday morning for that pre-planned surprise 50th Bday celebration I've been talking about for my wife. This evening I get in the Elantra to pick her up and when I started the car it began to shake VIOLENTLY, like I was in a commercial dough mixer. WTF!?? I saw the check engine light was on so I shut it off immediately. Curiously, I had the car out earlier without incident.
I restarted the car and it ran smoothly this time, but the check engine light remained. Calling the dealer, I was able to get a 9am appointment for tomorrow morning. I don't have an OBD-II scan tool to check the codes, but based on the symptoms, and recent poor gas mileage.

So the check engine light on my '12 with 5K miles came on 2 days ago. Called to make an appointment at the dealer for tomorrow...and today it goes off. Is it relatively safe to fore go the appointment and see what happens? I don't think it was related to the gas cap.

I just bought a used 2011 Elantra GLS and am having some issues that the dealer cant resolve. What is happening is the the Check Engine light comes on and off. It will be on for a day or so, then go off for a day or so, so I am thinking its the gas cap. So I tighten that thing up as good as I can and pulled the negative battery terminal and problem solved. About 2 days later, and about 200 miles later on the same tank of gas, the light pops back on. So I call the dealer and took it there the next day.
On my way to the dealer, the light goes out. They try and pull the code, but the ECU is showing nothing. I asked if the ECU stores codes and I was told that when the light goes out on its own it clears the ECU of the code. Not sure if that is true, but that is what I was told. So I drive the car home. I fill the car with gas, drive about 100 miles and the light comes on. I call the dealer the same day, take it over, and on the way like the car knows it goes off and guess what? Dealer cant do nothing.
Now to make a long story longer, this is what I know. The car is not a CA car. It was sold in GA and was a prior rental. It ended up in CA and was sold as a certified pre owned from a Hyundai Dealer, I actually bought the car from a Mitsubishi Dealer and they dealer traded for this car (thats another long story) the carfax does show that it failed emissions but passed after several attempts. Which I thought was odd on a ULEV vehicle. Since I liked the car so much and the price was good, I bought it since it did pass smog eventually.
Once I get the car home, I do my usual thorough look. I clean everything to my standards. I am cleaning the engine compartment and took the engine cover off. 1st thing I noticed was the Spark Plug Coil Packs all the 10mm bolts that hold them in were loose and 2 of them were completely off!! So I decided thats odd, so I pulled the plugs out and they were the NGK's so just in case I put a brand new set of the NGK laser Iridiums back in and tighten everything up. Then I notice where the PCV valve is on the valve cover, the hose that goes to that to the intake tube does not look stock. The hose looks like fuel line hose that someone put on it and the clamps are not stock. So I am canvasing for OEM replacements of those parts now. Then when I was installing the mud guards, on the drivers side rear tire where the gas filler tube is I notice another non OEM clamp. So someone was messing with this area of the car too.
The car is averaging 26-28mpg's in the city and I have been getting 35-37mpg's highway so I don't think there is anything major wrong here. I believe that either the PCV valve hose is kinked and may be causing a fault, or that since it was a prior rental that people were over filling the gas tank and maybe blew the expansion valve in the gas tank, causing the fault. I have no way to prove this since the light goes on and off and clears the ECU every time I take it in.

My Girlfriend just got a 2003 Hyundai Elantra and everything was running great on it the first month she had it BUT the check engine light was on.. After about a month she called me up while driving and said that the check engine light was blinking and the car would hardly move. So I got to the car and looked at it and I noticed the oil filter was a little loose so I tightened it good this time and added a little bit of oil. It actually moved but it would hesitate. So we had it towed to a shop and they read the codes from the check engine light and told us it was leaking oil from the motor some where (not specific) and it also needed a new O2 sensor.
So I replaced the catalytic converter underneath the car and also a new sensor along with a new set of spark plugs. It ran alot better and I left it at that. Now about a week later she was coming home and noticed that when she turned left or right that the battery light and brake light on the dash came on. She drove it home and when she turned in the driveway the car went dead. It started right back up and we got it to the house and left it over night. I went out this morning and again it started right up. but when I lifted the hood I noticed the belts on the pulleys were all spinning very slowly. I'm not sure if it could be a timing chain or if it just needs new pulleys.
