How do you fix code p0507 on a 2005 Hyundai sonata?

Answer 1

Code P0507 on a 2005 Hyundai Sonata indicates a high idle speed, which can be caused by a vacuum leak, a malfunctioning idle air control (IAC) valve, or issues with the throttle body. To fix it, start by inspecting all vacuum lines for leaks and replacing any damaged hoses. Next, clean or replace the IAC valve and ensure the throttle body is clean and functioning properly. If the problem persists after these steps, consider checking the engine control module (ECM) for updates or faults.
