Check engine light on and O/D OFF light flashing

My "99 Kia Sephia has both the check engine light and the O/D OFF light on & flashing. It has had trouble lately shifting between 2nd & 3rd (slipping). I plan on purchasing a scan tool, but have to wait until pay day next week. Any ideas?

I was facing a similar problem when I bought my car, I think the "check engine" lit due to a problem with shifting control system which obviously made the "O/D-off" flashes.The best solution in this case is to replace the malfunctioning shifting control system (a closed steel box that works like a computer).This is what I did and since then it's running perfectly.

I have a 99 Kia Sephia and it will not move in any gear the clutch seems to be engaging and disengaging but the transmission will not spin the wheels in any gear


It sounds like a bad clutch. It is the clutch if you can change gears with the clutch out and the engine running.

Where is the starter relay on 99 kia sephia?


The inside of the fuse box cover has a small diagram, also the manual has one. As for finding one online, I haven't seen one.

Also I suggest check your Kia Sephia Owners Manual.

Good luck (remember rated and comment this).

My check engine light/overdrive flashes on my 2000 kia sephia what could be the problem?


There are many different sources for the light to come on. Anything that caused combustion to fail, commonly called a misfire will set the light. Various sensors such as oxygen sensors that evaluate the exhaust before and after the gases are burned in the converter. Transmission codes may set the check engine light to appear. If the car is running okay, get it fixed in a reasonable amount of time such as within the month. It will probably save you fuel if you do. However if the Check engine light is flashing, you should not be driving it as damage is being done to the converter.
