Stop guessing. Start diagnosing. EngineIQ Diagnostic is an AI-powered automotive diagnostic app built to help drivers, DIYers, mobile mechanics, and technicians find problems — not just replace parts. Most code readers stop at the trouble code. EngineIQ helps you go further. Enter your vehicle symptoms, diagnostic trouble codes, freeze-frame data, scan notes, repair observations, and test results. EngineIQ Diagnostic analyzes the information and helps rank the most likely problems from most probable to least probable, giving you a smarter path forward before you waste money on random parts. Whether you are dealing with a check engine light, drivability issue, no-start condition, sensor fault, misfire, fuel problem, electrical concern, or confusing scan data, EngineIQ helps organize the diagnostic process so you know what to check next. EngineIQ Diagnostic helps you: • Rank likely causes based on the information you enter • Follow a step-by-step troubleshooting workflow • Avoid guessing from codes alone • Reduce random parts swapping • Organize symptoms, notes, reports, estimates, and invoices • Build a clearer diagnostic path before making repair decisions • Work smarter as a DIYer, driver, mobile mechanic, or technician EngineIQ is not just another scanner app. It is designed to help you think through the problem, understand possible causes, and follow a structured workflow toward the real issue. Codes do not always tell the whole story. A DTC trouble code may point you in a direction, but it does not automatically tell you which part failed. EngineIQ Diagnostic helps you combine codes, symptoms, data, and observations into a ranked diagnostic approach. No more guessing. No more throwing parts at the car. No more wondering what to test next. Start with a FREE version, then continue with a paid EngineIQ Diagnostic plan for as low as $7.99/month.

I’m lucky to be one of the first to try it out, I noticed the print button doesn’t do anything so hopefully in the next revision that gets fixed but everything else works, the versatility to add vehicle by name or VIN, to set prices and labor and everything to make into a report for the customer is really neat, at first it’s a lot to look at but it’s all there and extremely helpful! ## Frequently asked questions about EngineIQ Diagnostics ### What is EngineIQ Diagnostics?
