The Kia Sedona/Carnival Thread [ARCHIVE]

Here is the picture of the magnetic switch. This is located at the bottom of the fuel injector with a horizontal orientation.

As of now this switch does not react to any electrical voltage. So I am assuming this is busted unless there are experts in the field of diesel fuel injection systems.

how big is the switch?

[rodski]

The switch is about 3 inches long (including the piston) and the diameter is about 1 inch. Access to this switch is to snake your hand from the bottom (front) of the car to reach the lower right hand side of the injector. It would take an acrobat to reach the switch. You have to do it when the engine is cool because the radiator will singe your arms.

Upon researching I think the switch is ok. This has a natural magnet becasue when you press the piston it will pop out slowly. Applying pure 12vdc on the switch will not work. A pulse would reverse the magnets polarity and suck the piston in. This happens when you switch off the engine. Then the natural magnet will push out the piston ready for start condition.

Now the investigation is pointing towards how the piston got stuck.

I think that switch's natural state is 'OFF' to prevent fuel from entering the pump. You need a current to turn it 'ON' to allow fuel to flow in. It's used as a fuel cut-off. Unlike the old diesel engines, which they starve of air to shut it down, newer ones simply cut off fuel flow. This makes for a quicker and surer stop than the old stangle-the-engine-'til-it-shuts-down.

The magnetic switch thing is interesting. My carnival is already at the 122,500 kms mark and no major problem has come up yet. Hope the cause of the switch getting stuck will be discovered, maybe it can be prevented from happening.

Anybody here on the same or greater odo reading? What problems are to be expected?

OK here is my theory why the piston got stuck.

I few months ago while going to Calamba I extened my fuel to below 1/4 almost empty. After paying the toll I noticed na humina ang power ni olive. At first I thought clutch. I think medyo nag stuck na yung piston pero may fuel pang dumadaan. Inital diagnose is air in the fuel system.

Fast forward to the last week before the timing and oil pump repair. Mahina na talaga ang hatak ni olive. So after new year pinaservice ko na sa kaibigan na mechanic ni dad. During the course of the repair, the engine was tilted causing the piston to be stuck. So after installing the parts ang running on for 30 mins namatay yung engine.
Fully retracted na ang piston.

So when the magnetic switch was opened the piston is stuck inside the magnet. Tinaktak at lumabas na kaunti tapos hinila. then they lubicated it and the piston started to move in and out smoothly. Pag kabit nagstart at gumanda ang hatak.

The only way the piston will get stuck is when dirt gets in between the piston and the magnet's wall wedging itself and causing the piston to be stuck. Dirt must come from the diesel fuel. I use bioactive ng seaoil and occasionally load sa shell. Medyo malayo ang sea oil sucat sa las pinas. Bago lang yung fuel filter ko replaced last May 05.

So always use biodiesel and regularly replace the fuel filter and don't play russian roulette with the fuel gage. pag below 1/4 pa gas ka na.

Hello guys,

Ito na ang inaabangan ko. http://sedona.kia.com/ Kailan kaya darating sa atin ang model na ito. Ganda!!!!!!

Pagadating dito papalitan ko si olive para maging olive version II.

But when is it coming HERE? I've been asking that since September last year.

[rodski]

If you check the Korean website. 2.9CRDI WGT 170PS!!!!!!! Wow I like this.

Lensio - Paki translate naman sa amin yung specs sa korean website. Please. Pinaka mura ay 19M won. anong specs noon?

tnx
