Editorial Policy
At FixCarCodes, accuracy and driver safety come before everything else. Here's exactly how we create, review, and maintain our OBD-II diagnostic guides.
Our Content Creation Process
- Code Selection: We prioritize OBD-II codes that real drivers encounter most frequently, starting with emissions, ignition, and fuel system codes that trigger the majority of check engine lights.
- Research: Every guide starts with OBD-II standards documentation, manufacturer technical service bulletins (TSBs), and established diagnostic procedures used by professional mechanics.
- AI-Assisted Drafting: We use AI tools to help organize and draft comprehensive diagnostic guides. This allows us to cover more codes faster while maintaining consistency in format and safety warnings.
- Human Review: Every guide is reviewed for technical accuracy, safety considerations, and clarity. We verify diagnostic procedures, sensor specifications, and repair steps against manufacturer data.
- Quality Gate: Articles must meet minimum quality standards including comprehensive coverage (1,000+ words), accurate specifications, proper safety warnings, and clear severity ratings.
- Ongoing Updates: When new TSBs are released or diagnostic procedures are updated, we revise our guides accordingly.
Our Standards
- Accuracy: Sensor specifications, voltage ranges, and diagnostic procedures are verified against OBD-II standards and manufacturer documentation.
- Safety First: Every guide includes severity ratings and clear guidance on whether a code means "get it checked soon" or "stop driving immediately."
- Transparency: We clearly disclose that our content is AI-assisted and editorially reviewed. We don't pretend to be an ASE-certified shop — we're engineers and enthusiasts who research thoroughly.
- Honesty: Severity levels are realistic. If a code means potential catalytic converter damage from continued driving, we tell you plainly.
- Vehicle-Specific Notes: Where codes have different causes or procedures by make/model, we call that out explicitly.

Important: FixCarCodes guides are educational resources, not professional mechanical advice. Never work under a vehicle without proper jack stands, disconnect the battery before electrical work, and consult a certified mechanic if you're unsure about any repair.
