Editorial Policy

Our standard

Every page aims to be accurate, plain-English, and genuinely useful. We write for a car owner holding a code reader — not for a technician — and we keep the tone practical and honest.

How content is created

• Built from public, widely-cited OBD2 reference data
• Causes ranked by real-world likelihood, not alphabetical order
• Cost ranges are typical US-market figures, clearly labeled as estimates

Sources & transparency

We credit our open data sources (see About) and we don't invent statistics. If we're not confident in a fact, we leave it out rather than guess.

Updates & corrections

Every code page shows an "Updated" date. If you spot an error, email contact@obd2codelookup.com and we'll review and correct it.
