2006 Kia sportage. New alternater and battery now check engine light is on. What do I do the shop says it will take when computer recomizes???

The battery light comes on due to improper system voltage. The alternator output may not be sufficient therefore the engine control module signals the light to be on for the system to be checked.

Code 038 means the computer is getting a high voltage return in the heater circuit from the O2 sensor mounted after the catalytic converter. The O2 sensors have an internal heater to make them work as soon as you start the engine.
You would need to test the circuit to and from the sensor to find the real problem.

does your wiper control assembly come from mexico???
or Russia???

I called Kia about my check engine light and I told them my mechanic
read the computer and it says 02 sensor. She told me Kia does not sell out there codes to the computer in our cars and that I would have to take it to a Kia repair shop to get the correct reading form the computer

Have you checked the computer for trouble codes yet ?

Check the voltage coming out of the alternator with engine running it should be 13.0-14.7 volts.Usally when the battery light comes on the voltage is to low or not charging.If voltage is below 13.0 volts or higher than 15 volts then the alternator is faulty and will need to be replaced.

Hi there,

If you are sure that the alternator is not to blame - I assume it is new or the copper coils are in good condition - then I would say it is the battery itself.

If you can, open up the cells using a large screwdriver. If the cells are dry or there is not much liquid in them, top them up with distilled water from an auto shop.

Take your Kia for a drive (5 miles or so) to charge up the battery and see what it is like the next day in the morning. If the problem still persists, then it is the alternator.

Hope this helps and vote for me if so. Cheers!

Check your battery an eas way to know if its compleatly dead is to see if the lights come on or radio, you probley need a new alternater if the battery is dead again .

You'll need to have the car scanned and get the OBD II P Code. Most auto parts store will do it for free. That will tell you why the light is on.

Took it to the Kia dealer they said something was blocked and cleared it.
