Q: Electronic Throttle Issues on 2006 Kia Optima

Just today I got in my 2006.5 Optima and it took me 3 times to try and start it, and the check engine light came on when it finally did. I pressed on the gas as i pulled out of the parking slot and it would hardly go. It was not running bad, rough, or making any odd noises. I put it in drive and it would only go exactly 10mph even with the petal to the floor. I was close to home so i drove it back to my place. Got home, shut it off, then back on started right up and ran like nothing was wrong, but the check engine light was still on. I got the code read off of the computer and it gave code #s 2110 AND 21109. One was for a "System Forced RPM" and the other, "Throttle Body Range Performance" So from what I got out of this was that I need a new throttle sensor??? Ive got 70,000 miles on it. Is this a warranty item?

Your car has an Electronic Throttle Body assembly which is basically a drive by wire system. It could be the Throttle Pedal Sensor or the Electronic Throttle Body itself. Can you get the P codes so we can be a bit more specific, such as a P0301 type of format, this will gives us a better handle on which Position Sensor in the System is defective ( there are 4 ). As far the warranty goes, most vehicles have a 3 yr/50,000 mile warranty on their Emissions Systems. There are a very few exceptions to this though, but you need to call the dealer and ask them to check your VIN ( Vehicle Identification Number ) on the factory service database to see your if car is entitled to a special warranty exception. Good Luck!
