Troubleshooting Hints

WARNING: This page is about a different car, the 2004 Hyundai Santa Fe and 2003 Hyundai Santa Fe. However, it is still accessible from the selected car via links, so may be relevant.

If the fast idle speed is not adequate or the engine gives off dark smoke during warm-up, the engine coolant temperature sensor might be the cause.
