Check engine light on? CarIQ tells you exactly what your car's OBD-II code means — in plain English, right on your phone. Search or browse a library of 900+ diagnostic trouble codes covering every generic OBD-II code plus manufacturer-specific codes for dozens of makes. Pick your vehicle once and CarIQ surfaces the codes that actually apply to it. FREE, ALWAYS: • Full code search across the entire catalog • Code title, category, and urgency at a glance • Plain-language description of what the code means • Save favorites and keep a history of recently viewed codes UNLOCK WITH OBD EXPERT PRO: • Possible causes behind the code • Typical symptoms to watch for • Estimated repair cost ranges • On-device AI explanations powered by Apple Intelligence, tailored to the specific code No obligation to guess, no waiting for a shop appointment just to find out what a code means. CarIQ helps you walk into the conversation informed — whether you're doing your own wrenching or deciding if it's worth a trip to the mechanic. Everything runs on your device. AI explanations use Apple Intelligence on-device processing — nothing is sent to a server. CarIQ is not a replacement for a certified mechanic's diagnosis. Repair cost estimates are general guidance, not a quote. OBD EXPERT PRO SUBSCRIPTION: OBD Expert Pro unlocks possible causes, symptoms, repair cost estimates, and on-device AI explanations. Choose Monthly, Annual, or Lifetime at checkout — exact pricing is shown in the App Store before you buy. Monthly and Annual are auto-renewing subscriptions: payment is charged to your Apple ID at confirmation of purchase, and each subscription renews automatically within 24 hours before the end of the current period unless auto-renew is turned off at least 24 hours before the period ends. Manage or cancel anytime in your Apple ID Account Settings. Lifetime is a one-time, non-renewing purchase.
