Have the engine codes read. It may hold the answer or put you in the right direction. This could be a defective speed sensor (on your trani), dirty or defective MAP or MAF sensor, clogged fuel or air filter, a calibration issue (that the dealer can take care of) Call the dealer (Service Dept.) and ask if there any notices or recalls for your vehicle. Let me know if I can be anymore help. good luck.

SOURCE: 2006 Kia Sedona's check engine light

try not to fill up the tank while the car is running. maybe there is a bad seal on the gas cap now. i would simply reccomend taking it to the nearest advanced auto part, autozone, jiffy lube...anything of that matter and get them to read the code for you[they should do it for free]. Make sure to write it down, come back here and let me know what it said. its probably not a big deal

SOURCE: I have a 2002 Kia Sedona. The check engine light

YOU NEED TO SCAN IT.TO SEE WHAT CODE THE CHECK ENGINE LIGHT IS COMING UP WITH.IT COULD BE THE TORQUE CONVERTER ON TRANSMISSION REMAINING LOCK UP OR MASS AIR FLOW SENSOR.IF YOU REPLACE THE FUEL PUMP.YOUR FUEL FILTER WILL CAUSE THE SAME PROBLEM IF ITS STOPPED UP.

SOURCE: 2003 kia sedona rough idle--check engine light

The only thingI can say is that there is a problem that is affecting the entire bank on one side of the engine. This automatcally eliminates things like Mass Air Flow (MAF) sensor, Manifold Absolute Pressure (MAP) sensor, Throttle Position Sensor (TPS), Crankshaft Position Sensor (CKP) etc. because failure of these things will affect BOTH banks, not one.

I have seen things like a totally skewed upstream Oxygen sensor on one side cause misfire codes for all cylinders on one bank. It is pretty rare, but it CAN happen. This can usually be verified by graphing the O2 Sensor PIDs for both sensors and comparing the graphs.

If the scaner data should be showing SOMETHING that is not right on one side - i.e. fuel trims, injector pulse width, etc.
I would also be looking into the possibility of one of the cams on that side to be 1 tooth off of the correct timing. This can cause problems while the engine is running and will not necessarily show up on a cranking compression test. One way to verify this is to perform a RUNNING compression test. With a warmed-up engine, pull one spark plug out at a time and check the compression with the engine running. Do BOTH sides, so you can compare the readings. If the entire 1-3-5 bank is lower than the 2-4-6 bank, then valve timing is most likely the cause.

KIa Mentor engine light


if the light came on it could be a fluid level warning. In most models today they don't have a light or gauge for the levels. I would check this first. you mention a hesitation, this could be as simple as changing the fuel filter or a faulty O2 sensor. Best bet is ti have a diagnostic scan done to find out if there is an active code present in your ECM.please rate this.....thanks
