To contact OBD2 Code Hub, send us an email. Write to us about a code guide, a correction, or a question. We read every message that arrives, and we appreciate hearing from readers.

How to contact OBD2 Code Hub

Email is the only way to reach us. There is no phone line, no office address, and no contact form on this site.

[email protected]

What to include in your message

Please include three things so we can answer usefully. First, your trouble code, for example P0300. Second, your car’s year, make, and model. Third, what you already tried. Because of these details, we can point you in the right direction. A clear subject line also helps us sort your message faster.

What not to send

Please do not send personal documents, and do not send payment details. We will never ask for them by email.

Please note

This inbox is for site questions and corrections. It is not live car diagnosis, and it is not emergency help. For a flashing check engine light or a car that is unsafe to drive, see a mechanic in person. If you want to look up a code yourself first, use the Code Lookup tool at /code-lookup/.
