20 Most Recent 2003 Kia Sedona Questions & Answers


HI there; Basically this means that your downstream oxygen sensor on the catalytic converter on bank 2 is detecting that the converter is not working as efficiently as it should be (according to specifications). It is part of the vehicle emissions system and the comb may have partially collapsed.

I would start by inspecting for exhaust leaks first. Next; measure the voltage at the oxygen sensor on Bank 2. In fact, go ahead and test each oxygen O2 sensor while you're there. The voltages should be cycling somewhere between 0.2 and 0.8 Volts. If the voltages are optimal and there are no exhaust leaks, replace the catalytic converter.

NOTE_ Many vehicle manufacturers offer a much longer warranty on emission-related parts. So if you have a newer car but it is out of the original bumper-to-bumper warranty; there still may be warranty coverage on this type of issue. Many manufacturers issue a five year, unlimited mileage warranty on these items(O2 sensors). I would defiantly check on that...

yes, actuator--black box with motor and gears inside that rotates the blend door. I think yours is right on the front of the heater box, to the right of center under dash. Remove actuator and check door for proper operation. If it opens and closes smoothly by hand, replace the actuator. If the door is sticking, you will probably have to take the heater box out of the car, split it open, and repair whatever is keeping it from opening.

Hi Charles The answer is NO, the Kia sedona does not have a fuel shutoff switch.

Check the volume of fluid in the master cylinder reservoir. Low fluid would account for an intermittent brake light.
Check to be certain you are not leaking any fluid.
Noises may be from many causes.
Did you "bed" the pads & rotors?

This happened to me, I removed the interior light fixture on the rear hatch and reached in to pull the connecting rod, this works for an one off opening, you will need to take the panel off once the hatch is open and repair your outer handle, our connection was broken at the handle which I repaired and it works great. Hope this helps.

can a kia 2.9 diesel fuel pump be changed without it been chiped to the vehcle

Check continuity of cable to pump. Do you get a voltage reading on supply to pump? If no the wire has a break (or worse been earthed )somewhere

Change the fuel filter and see it that helps. It sounds like a fuel supply problem, and the filter is the least expensive most likely place to start.

sounds like you are getting water into the connections and possibly have a bad earth connection. Suggest you check all light connections for water ingression.

-Here next step to work on: -Check for fuel pressure. If not within specification then the pump is not function the way it should. -Check fuel pressure regulator. It hold pressure or not. It not then the pressure regulator need to be replace. Good luck Mai

Most likely a chaffed wire in the door hinge area.

Have a cylinder leakdown test done...likely they missed another bent valve. I'm betting it's an exahust, because it would be less drivable if it was an intake, but regardless, I'll bet that is your problem.

Your problem sounds like you have a bad crankshaft position sensor. You will not get a trouble code (check engine light). This will cause the vehicle to suddenly stall. You cannot change the idle on this vehicle, or any FI modern vehicle contrary to a previous post. It is controlled by the engine management computer by way of an idle air control circuit on the throttle body.
