Unfortunately, when you see the $7E8 and $7E9 engine codes, it's not necessarily a cause for concern. These codes can actually represent a wide range of issues. If your OBD-II tool is unable to interpret the fault code data in hexadecimal format, it may provide general "placeholder" codes. The $7E8 code may suggest an engine problem with your Hyundai Sonata, but further details are needed to pinpoint the exact issue. Your next step should be to visit a trusted auto parts store for a complimentary scan, as this is often more cost-effective than purchasing a new scan tool. With more precise error code information, we can better explore the potential problems with your vehicle.
