Get it scanned for errors. The VSS or the speed sender unit may be damaged or not seated/fitted correctly.

SOURCE: 99 kia sephia, o/d light is flashing on dash

Hi. this is the result of a failed O/D shift solenoid that is located inside the transmission pan. you will need to drop the trans pan to access this solenoid. once replaced, the O/D option will become operational once more.


Please rate and have a great day:)

SOURCE: 2001 Kia Sephia "kia logic contol" player flashing CODE

You will need to contact the dealer. Radio codes are only supplied thru the dealer or you can search online for places that sell the code.

Chances are you will need to pay for the code or replace the radio with one that is an upgrade with no code needed.

Erratic idling revs up and down, check engine light on, o/d off dash light is flashing


There is a small electric motor call IDLE AIR CONTROL (IAC).

It add rpm when there is load like headlight,radio,power window while you at idle.

Just to bump up the power a little to keep everything operate smoothly.

When IAC is not functioning it will give you uneven idle.

Get the OBD-II code and repost. It will help you to get to the real problem.

OBD-II connector is 18" from the center of the lower dashboard. Scanner is about $50 to start.
