Connect a compatible Bluetooth ELM327 adapter to read diagnostic trouble codes, view live sensor data and graphs, and understand check-engine warnings. The new Vehicle Health Center brings together a health snapshot, mileage-based maintenance planning, official NHTSA recall checks for saved vehicles, inspection-readiness guidance, and a report you can share with a mechanic. Ask the AI Mechanic vehicle-aware questions about symptoms and active codes. Plier suggests practical tests, explains possible causes, and helps you decide what to check before replacing parts. You can also review supported freeze-frame and oxygen-sensor test data. Available data varies by vehicle, adapter, protocol, and model year.
