What is the recommended method to confirm CARB approval when the Aftermarket Parts Label is missing or illegible?

• A. Compare the part number against CARB EO listings or the parts manufacturer's catalog
• B. Ignore the issue
• C. Replace the part with a CARB-approved one
• D. Ask the owner for documentation

Answer: (A)

When a CARB-approved aftermarket part doesn’t have a readable label, the right move is to verify its approval by cross-checking the exact part number against official CARB EO listings or the part manufacturer’s catalog. The EO listings are the official records that show which parts are approved for specific vehicles and emissions categories, so matching the part number to an entry there confirms compliance. The manufacturer’s catalog provides the same confirmation from a trusted source associated with the part. Relying on these published references ensures you’re making a determination based on authoritative documentation rather than a possibly missing label or owner-provided notes. If the part number doesn’t appear in those sources, you’d treat it as not CARB-approved and take appropriate action before installation.
