If your air pressure is ok in your tires, then your light stays on because the batteries in the sensors have gone bad. They only have a life span of 4-6 years or so. You have to replace the sensors in the wheels and then "calibrate" them. If you are doing one, do all four, because if one goes bad the others are close behind it and you don't want to have to calibrate them each time one goes bad. I ordered mine online, saving almost $200 ! Your dealer or some tire dealers can install and calibrate them.
Check the engine temperature sensor. There should be two of them, one that reports it inside of the car and one that reports it to the ECU. The one that reports it to the ECU has likely failed and needs to be replaced.
could be but it is up to the dealer to fix it under warranty regardless of the warranty period running out
faults reported during a warranty period but not fixed remain under warranty until they are fixed
The dealer may argue this so get a lawyer involved and talk to kia head office and report the dealer incompenence
I called Kia about my check engine light and I told them my mechanic read the computer and it says 02 sensor. She told me Kia does not sell out there codes to the computer in our cars and that I would have to take it to a Kia repair shop to get the correct reading form the computer
Before I bought the Mass Airflow Sensor, I looked up the codes again for the 2007 3.8L Kia Sedona. One listing was "massive vacuum leak". I took all the hoses and debris collectors off of the engine, and upon close inspection; the large air hose that connects the air filter to the intake manifold was dry rotted at ALL the ridges. I flexed the hose a few times and saw where the vacuum leaks were occurring. I also removed the EGR hose for inspection and found the hose was faulty as well. Since these parts are "dealer only", I used duct tape to seal the leaks as a temp fix, filled the gas tank and used fuel injector cleaner. Disconnected the neg. battery terminal, reset the codes, and the check engine light turned off. Runs like a champ now. Vehicle has 119,000 miles so I guess wear and tear like this is to be expected. New hoses from online parts dealer totaled 130.00. I got off easy I think.
Give your computer a reset. Disconnect the battery terminals (positive and negative) for about 15-20 minutes. When time passes, put them back on wait 10 minutes and give it a try. Everything in the computer should be reset and you should have no more blinking air bag indicator. Hope this helps!
