SinoTrack V019 OBD2 Bluetooth Scanner Dongle — Wireless Car Code Reader, Live Data for iOS & Android

The SinoTrack V019 is a compact Bluetooth OBD2 scanner that reads diagnostic trouble codes, streams live vehicle data, and helps you identify engine and system issues on iOS and Android devices.

If you want quick insight into your car’s health without a trip to the shop, this small Bluetooth 4.2 dongle plugs into any OBDII port and connects to popular mobile apps to display codes, real-time sensor values, and vehicle info. It supports all standard OBD-II protocols for 1996-and-newer gasoline and diesel cars and light trucks sold in the U.S., delivering fast reads and language options for wider accessibility.

How does the V019 show what’s wrong with my vehicle?

The V019 retrieves diagnostic trouble codes (DTCs) from the engine control unit and gives readable definitions so you can understand likely causes. It also captures freeze-frame snapshots so you can see engine conditions when a fault occurred.

• Reads and clears generic and manufacturer-specific DTCs
• Provides on-screen code definitions and DTC library
• Stores freeze-frame data for context at the time of error

Can I monitor live performance and sensors with this reader?

Yes — plug the dongle in and stream live gauge data to your phone or tablet to watch parameters like coolant temperature, oxygen sensors, mass air flow, and battery voltage. Live data helps you spot trends and verify repairs in real time.

• Live sensor stream for engine and emission-related inputs
• Monitors fuel economy and real-time engine metrics
• Records data with compatible mobile apps for review

Which cars are compatible and are there any limitations?

The device works with most cars and light trucks sold in the U.S. that comply with OBD-II standards (1996 and newer), for gasoline and diesel engines. It does not support hybrid, plug-in hybrid, or full-electric vehicles that lack a conventional OBD-II emissions port.

• Compatible with all OBD-II protocols used in U.S. models since 1996
