About a week ago my 2005 Kia Sedona began bogging down and chugging. Shortly after the check engine light came on. I took it to autozone for diagnostics and it came back as an electrical issue i.e. the ignition coil sensor. I checked the sensor and it appears fine. I cleaned the connection and the van ran fine for a day or two. Then I noticed that the fans are not kicking on and that is when the van began bogging down.

it is located on the drivers side underneath the van. you have to remove it from the underside of the car. you will need a 17 millimeter socket or wrench. Remove the ground cable before attempting to remove the starter.

I think if the self adjusters are working properly you should be able to push the parking brake pedal (e-brake) to the floor once and release pedal. .

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

on the low side fitting, Follow a/c hoses, both will have fittings, some are marked with a blue cap. Remove cap and recharge at that point

Testimonial: "I have two yellow caps one marked h and l and i assume it is the l cap where i charge the unit."

I assume by now you have this problem fixed, but if not, or for the benefit of others looking for help, try replacing the coil on the #5 cyl as well as the injector. Ours did same thing, except fault code was on #2 cyl, so I got the parts from local parts store for about $150 total, and completed the repairs myself on my wife's 2003 Sedona. Now i can start on the rear heater issues, the knocking sound coming from the LF tire area while in motion, and replacing all brake pads. 92,000 on the odo. I'll spend the extra $ and go with the Honda Odyssey next time.
