How do you change a Throttle Position Switch in a 2006 Kia Sedona? on 2006 Kia Sedona

When the temperature outside is moderately cold the van will display the check engine light along with the traction control light and not allow throttle inputs. I have to turn the vehicle off and on, then it will be ok for a minute or 2, and continue doing this for up to 5 minutes. Once the van gets really warmed up it stops, however the check engine light will stay on .
