Sedona Engine Management Light

jackamanfan · 08-09-2005, 12:49 PM

My sedona regularly displays the Engine Management 'Check' light on the dash when towing a Caravan. When I have the system checked by kia, there is nothing recorded on the kia diagnostic equipment and no problems found. I just wonder if anyone else has experieced this and if it is just a feature of the sedona?

Having a guess here......
As you only get this happen when towing a caravan, i wonder if your secondary electrics are wired a bit wrongly?
Could cause charge/batt volts to go below ECU threshold, causing a check engine light.

Hi I have played with cars with engine management systems for some years now and my hunch is that you need a new fuel filter.
The current one is probably partially blocked causing lean mixtures when under hi loads such as towing. The lean mixtures measured by the O2 sensor is relayed to the ECM which subsequently runs out of control authority to compensate for the lean mixture and assumes there is a EM fault.

Since the Sedona is OBD-II equipped, the code would be stored whether the light is on or off. I believe if the problem "fixes itself" and no malfunction is detected, the code will eventually clear itself. I'm pretty sure you have to go through 50 driving cycles before that happens. Also, if you disconnect the battery the code will be cleared.

I agree with Classic boy though, it sounds like the engine is starving for fuel under a load.

Theres a good chance as the OP is UK based that it's a diesel engined model.

Have you tried draining off the seperator off the bottom of the diesel filter.........b**tard isn't the word - in the end I unbolted the housing off the wing.
Point two anyone know what the filter equvilant is because im too mean to buy a kia filter at 30 + pound

I meant to add that in the handbook it does say about the filter drain bringing up the light, it also says change the filter at 20k too but thats not what my dealer was saying ?

Filter is a Delphi unit, as it's a Delphi injection system on the diesels, plenty of other cars use it, try a motor factors such as Partco.

Hello Eco,

Partco 020 8743-3742 nearest branch to me quoted me £17-00, pads and shoes were a good price to.

Stockwell Motors 020 7582-3666 was a tad more exspensive

Motorbitz if there is an outlet your way.

Mines due a service,

I call a motor spares place near where Iwork in Leeds ( Beeston Motor Spares.....yep Beeston...where the suicide bombers lived )

Asked for a price for air , oil & fuel filters and they said £25 quid the lot.

The main reason I replied to this post though is the qty of oil this 2.9 diesel takes is pretty big, its 7.4 ltrs so that means two tubs !!!!

Anyway, because I also run another diesel and I use only Millers XFD full synthetic oil, I normally pay £24.99 from a local car parts place. Both cars are due a service so that would mean £75 on oil.

I contacted Millers Oil direct as they are in Brighouse which I pass on my way home every night. They can supply me a 5 gal ( 25ltr ) tub for £85. So I think thats the route I'll take.....
