Hyundai Repair: Hyundai, throttle position sensor, throttle cable

Question
I have fault codes: P1613, P1714, and P0121.  What parts do I need to replace? Waht adjustments need to be mande?

Answer
P0121 indicates a problem with the throttle position sensor and P1714 indicates a problem with the idle switch.  The fact that you have these codes together suggests there's some issue with the throttle cable adjustment or throttle position sensor adjustment.

The problem indicated by P1613 varies by year and model, so I'll need that information to give you a better answer on that code.  The year and model will also assist me in advising you on how to further approach the other codes, since it'll give me additional information regarding the system on your particular vehicle.
