Hi

Before you turn out the light you should have a code read carried out just to make sure nothing sinister is going on with the management system.

If the car is running ok then the code will probably either pertian to the O2 sensor, the EVAP system, or a drop in catalytic efficiency, but this isn't set in stone, just the most popular scenarios.

Very best regards

Reseting the cpu will clear the check engine code however it will not fix the problem that caused the check engine light to come on. The most common cause of failing emissions is the O2 Sensor. This sensor will trigger the check engine light when it is failing. The good news is that the Oxygen senser is pretty cheap and is mounted on your exhuast so it is fairly easy to replace yourself. I suggest replacing your O2 sensor the clear the computer by disconnecting the negative battery terminal and leave it disconnected for a few moments, hook up the negative again and it's all clear. Take your car back threw emmisions and you should be all set.

Hope this helps

P0715 means Input/Turbine Speed Sensor Circuit Malfunction.

replace your gas cap and clear codes, then wait and see if light comes back on, if it does you have a more serious problem like a fuel tank leak or a defective fuel tank pressure sensor.

2008 Kia Optima shuts off while driving


There is very likely a code being retained in the engine computer. If you are able go to your friendly auto parts store and ask for a complimentary scan for OBDII codes. Most Auto Parts stores will provide this service at no cost. From the scan you will be able with the advice from the parts store determine the most likely culprit for the stalling.

This is the best method for troubleshooting a 2008 vehicall.

Hope this helps?

How to reset my check engine light on 2008 Kia optima or what causes it to come on


If u goto your local "Advance Auto" parts store they can, free of charge, plug a hand held scanner into your OBD-II port, typically under steering wheel down by knee's and read what code has been set causing the light to come on. Could be as simple as loose gas cap to something major. They should be able to clear it as well or at least offer a good reason for it and often the correct fix to eliminate it. Good luck!
