The fastest way to reach the maintainer, report an error in a code definition, or suggest a code that should get a full guide is the project's public issue tracker:

github.com/mraqeelpkorg-glitch/obd2codes/issues

When you report a problem with a page, please include the code (for example P0420), the page address, and what looks wrong. Corrections to code data are checked against the source dataset and published definitions before they are applied.

Please note: we cannot diagnose your vehicle by message. A code read from your car plus the symptoms you describe is a starting point — the guides on this site walk through the same checks a technician would run, in the same order.
