About FixCarCodes
FixCarCodes provides free, accurate diagnostic guides for OBD-II trouble codes. We help car owners diagnose and understand check engine light codes — saving hundreds on unnecessary dealership visits.
Our Mission
When your check engine light comes on during your commute, you shouldn't have to wade through forums full of guesswork. FixCarCodes gives you clear, step-by-step diagnostic instructions — the same procedures professional automotive mechanics use — written so anyone can follow them.
How We Create Our Guides
- DTC Code Research: We compile information from manufacturer technical service bulletins (TSBs), OBD-II standards documentation, and widely-known diagnostic procedures for each trouble code.
- AI-Assisted Drafting: Our guides are drafted with AI assistance to ensure comprehensive coverage of symptoms, causes, and step-by-step diagnostic procedures.
- Accuracy Review: We cross-reference diagnostic steps against manufacturer specs and common mechanic procedures. However, vehicles vary — always verify part numbers and readings for your specific make and model.
- Safety First: Every guide includes clear guidance on when a problem requires a certified automotive mechanic. We'd rather you stay safe than save $100.
Transparency note: FixCarCodes guides are AI-assisted and editorially reviewed. While we strive for accuracy, we are not a substitute for a qualified automotive mechanic. If you're unsure about any repair, please consult a certified professional.
