Hi Al, I'm glad to help!

Al, the code you have P0446 is a malfunction in the emission systems "Vent Control Circuit". Anytime you have a code that involves the "CIRCUIT" It could be the wiring, the part itself or the computer operating the part. The best way to find out if its the wiring or computer is to replace the part, clear the codes and see if it comes back, if the code never comes back then you have fixed the problem. If it does come back the check all the related wiring and connectors. Hope this helps and have an awesome day Al.

SOURCE: 2002 kia sedona 3.5l has rough idle replaced plugs wires and coil

this vehicle has coil packs for the ignition correct? have you ran the engine at night with all surrounding lights outs so its really dark. spray a mist of water on the coil packs and spark plug wires to see if you have spark/voltage leaks jumping out from them. sometimes the tiny sparks will be so fine and skinny you can barely see them so it needs to be dark. hope this helps your trouble shooting. a coil pack could have such a fine crack for the voltage to leak from that you cant see it.

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: 05 Kia Sedona 2.9 diesel, sometimes doesnt start

if the immo light doesnt come on it means the ecu has left the immobilizer on. it is a commen fault on kia. if you lock and unlock the car or sometimes just take the key out the ignition then put it back in it sorts the problem. if you dont see the IMMO light dont attempt to start it because it wont fire

SOURCE: 2002 kia sedona missing when takeing off and going

I had this same problem at 113,000 miles on my Sedona and I replaced the spark plugs and wires and it took care of this missing. It's an expensive job unless you do it yourself. However, the check engine light came back on so I have to replace the o2 sensor also. Here is a link to a tutorial on how to change the spark plugs. This is the best information you will find for changing spark plugs on a Sedona.

My 2002 kia sedona won't idle until warms up, dies when put into gear ...any ideas??


Is the check engine light on? you could have a bad ignition fail sensor, TPS sensor, or bad o2 sensor. it could also be a bad mass air flow sensor or a vacuum leak. without a code to help pin point the problem I'd start by checking those things first. Maybe try unplugging the mass airflow sensor and start it up and see if anything changes.

Kia p0431, p0446, p0715


They are three separate issues.
Code 431 involves the O2 sensors and the catalytic converter, code 446 is for the evap vent control for the gas tank, and code 715 is for the input shaft speed sensor in the transaxle.
The engine temp and other factors would need to be checked for code 431, and the sensors would need to be tested for the other two codes.

The Check Engine Light has been on in my 2002 Kia Sedona van for over 6 months. I have taken it to the dealer several times and they can't seem to find out what is wrong. They have ruled out all the...


I don't know what would cause this but the dealer should have scanned for codes and each of these codes are caused by one or more issues. It sounds like they didn't complete the diagnostics job that they were paid to do.

I hope this helps.

Kia sedona 2002 smell gas in the interior of car


Sounds like you might have bad O2 sensors, leaking fuel injector O rings or a bad fuel pressure regulator. Check that the vacuum hose to the pressure regulator is connected and no cracks or holes in it. Any check engine light?
