Question about 2001 Hyundai Tiburon
This problem has happened twice with my car. The first time i was coming up a fairly steep hill when i would get above about 2500 rpms id say the check engine light started flashing and the engine began to sputter like it was going to cut out. That was back in september id say. Now earlier today i was on the highway and i had a similar issue. I was doin around 65 when i heard the engine sputter again and the check engine light started flashing again so i let of the gas for a minute and it went away after a few seconds and then the rest of the drive seemed normal i was only heading to work which is about a 4 mi drive. Now it is alot colder out then it was back then and i hadnt drivin my car in about 2 days but im not sure what this issue could be. I do have an exhaust leak but im not sure if this would be related to this issue or not.
hi there, i have a 2003 sonata and my car did the same. it stalled and the engine light stayed on but managed to get going again. i took it to Hyundai and it was the crank angle sensor. it needed replacing at NZD180.00 with 3 hours labour to do it. evidently they remove the front of the engine and cam belt etc. the workshop at Hyundai did it and charged 3 hours, not sure if that was excessive or not.

The vacuum modulator on the side of the transmission has a leak (rubber diaphragm inside has ruputred. ($15 AutoZone).
Or other major vacuum leak (hose to the modulator may had come off or brittle, or clogged, or broken.
The downshifting is now being done by the "mechanical backup" to the vacuum system
Hope this helps!

I am having the exact same problem with my 2001 Hyundai Elantra. I was told that the engine code that comes up when the sensor is on is called "Absolute Pressure In The Manifold". I was told by a "Hyundai Specialist" that when that code comes up it usually means that the seal on the manifold is Fuct. When my mechanic checked that out for me he had noticed that my manifold had 4 cracks in it(can varify cause he showed me). He replaced the manifold and gasket. The car ran fine for about 2-3 days and since then the problem has since come back and my check engine light will no longer go on/off it only stays on. Because of the check engine light always staying on I have noticed that on many occasions my car will hiccup many times in a row. The only way to stop the hiccup I have noticed is to take my foot right of the gas for approx. 2-3 sec then car will continue without hiccup(till it happends all over again). All in all I have been having this problem now for approx. 1 year and if there is somehow someway it could be repaired I would appretiate it.

I had this exact same problem...turns out it has to do with a recall having to do with the stop lamp switch. I took it to the dealership and it only took about 20 minutes form them to fix it.
Hyundai is recalling 531,894 MY 2006-2007 Accent, Entourage, Sonata, MY 2007 Azera, Elantra and Santa FE, MY 2005-2007 Tucson and MY 2007-2008 Veracruz vehicles. The stop lamp switch in the affected vehicles may malfunction. A malfunctioning stop lamp switch may cause the brake lights to not illuminate when the brake pedal is depressed or may cause the brake lights to remain illuminated when the brake pedal is released. A stop lamp switch malfunction may also affect the operation of the brake-transmission shift interlock feature so the transmission shifter would not be able to be shifted out of the park position. It may also cause the electronic stability control (ESC) malfunction light to illuminate, and it may not deactivate the cruise control when the brake pedal is depressed. Any of these malfunctions, alone or in combination, may lead to a crash. Dealers will replace the stop lamp switch free of charge. The recall began on April 23, 2009. Owners may contact the Hyundai Customer Assistance Center at 1-800-633-5151. This recall was the result of a Preliminary Evaluation conducted by the Office of Defects Investigation.
