Question about 2005 Kia Sedona

2005 Kia Sedona Catalytic Converter

Had my engine replaced on my 2005 Kia Sedona. Has 85,000 miles on it. Drove home last night (!) car was fine. Drove to get hair cut and home. Car fine. Drove daughter to school--check engine light on. Took back to dealer (who replaced engine) and they put it on the code reader. Came back that I had a "fault" in my catalytic converter. They said that they checked the converter, it still reads in the "normal" range, but not perfect. They said that, at some point, it will need to be replaced. They cleared the code and then drove it for 30 miles on the freeway. No code. I drove it to work and parked it in the lot. What they told me was that my engine may have let a carbon particle go and since my catalytic converter is not perfect, that is what threw the code. The dealer said that they don't expect teh code to come back, but if it does, not to panic. If my car is driving okay, it may just have happened again. Does this make sense/sound plausible to any of you?

Possible but as the cat converter is a mass honeycomb of openings around 1/2 mm one small spot of carbon would not cause the fault
when a new engine is fitted, the oxygen sensor will take time to read the operation of the cat converter and if the cat is failing as they said then at some point the readings may be outside the set parameters for the sensor
That in turn will cause the heated oxygen sensor to go out of parameters and possibly put the light on
they are partially correct to say not to worry about the cat converter until it starts to break down then it will block the exhaust or you get an inspection and a test ordered
At this point in time , drive it and put some saving aside for a new cat converter and have it changed when you can afford it

SOURCE: car dies when driving,check engine light comes on.

There is a good chance it could be your fuel pump , however if the check engine light is coming on and the dealer cant tell you what is wrong , try a different dealer or another shop. Second opinions never hurt.

SOURCE: Check engine light on 2004

I would suggest checking with dealer as most KIAs have a 100,000 mile warranty and catalytic converter as part of the emissions equipment should be covered.

Take it to another shop and have them do a compression check. If the compression is low, you have found the problem. If the compression is the same as the other cylinders, trade the fuel injector at that cylinder with another cylinder and see if the problem moves. If the problem moves (misfire code in different hole), the injector is bad. If the problem didn't move, and the compression is fine, then you have a vacuum leak on the intake runner to that cylinder, possibly the intake gasket. Print this and give it to your new mechanic.

2005 Kia Sedona 3.5 eng. will not go over 15 mph with pedal to the floor cleaned the throttle with spray cleaner and did CPS two weeks ago and coils and tune up last night still same problem

I would recommend a scan test on the ECM to see if any trouble codes are there and point you in the right direction. The MAF sensors on thesr vehicles are problamatic and cause throttle actuator to go into limp mode. Unplug the MAF sensor and see if it makes any difference

Sounds like a catalytic converter problem. Driving through deep water can damage. See if you have exhaust flow at the tailpipe. The A/C is most likely low on Freon.

Most "common" cause is and engine misfire that causes unburned fuel to enter the converter and overheat/melt the catalyst. The converter is covered by 8yr/80,000 mile warranty for defects, and may be covered thru Kia. On a positive note we have a 2005 sedona shuttle van a work with 250,000 miles on it and qoing strong.
