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.
