Question

Where is the Idle Air Control valve on a 2006 Kia Rio 1.6L? I have a P0507 code

Answer 1

P0507 Idle air control system higher than expected

​ 

The ISC when you set a P0507, look for a vacuum leak, these are the number one cause for the code to set especially at the throttle body, the MAF (mass airflow boot), if all of is secured perform a throttle body cleaning, carbon could of build-up at the throttle body opening.
