Panlong OBD2 Bluetooth Scanner for Android — Reads & Clears Codes, Streams Live Data, Resets Check Engine Light

Panlong Bluetooth OBD2 Scanner turns your Android phone or tablet into a vehicle diagnostic reader to read/clear codes and monitor live sensor data.

Designed for DIYers and technicians alike, this compact Panlong OBDII adapter connects to Android devices and popular apps to reveal engine trouble codes, real-time parameters, and help switch off the Check Engine Light after fixes. It's ELM327-compatible and supports a wide range of gas and light-diesel vehicles built to OBDII standards, giving quick access to information that helps you understand vehicle issues before heading to a shop.

How will this tool help me diagnose a check-engine light?

Plug the Panlong adapter into the vehicle’s OBDII port and pair it with an Android diagnostic app to retrieve stored and pending diagnostic trouble codes (DTCs). The app translates codes into descriptions so you can identify the likely subsystem at fault.

• Reads stored, pending, and manufacturer-specific codes
• Clears codes and can reset the Check Engine Light after repairs
• Shows code definitions in-app for faster troubleshooting

Which cars and apps are compatible with this Panlong OBD2 scanner?

This interface follows the ELM327 standard and supports nine OBDII protocols, covering most 1996+ US, 2000+ EU/Asian 12V gasoline and light-diesel vehicles, plus newer OBDII-compliant models. It works with many Android apps available on Google Play so you can pick the feature set you prefer.

• Compatible with apps like Torque, DashCommand, Car Scanner, OBD Fusion and more
• Supports Toyota/Lexus hybrid features with the Dr. Prius app
• Android phones and tablets only — not compatible with iOS on this version

How do I set it up and avoid connection issues?

Install a compatible Android app, plug the Panlong adapter into the vehicle OBDII port, and pair over Bluetooth. If the adapter name doesn’t appear in Bluetooth scans, open the app and let the app detect the device instead; unpair previous adapters when switching devices.

• Plug into the OBDII port (usually under the dash) and power is supplied by the vehicle
• Open your chosen Android OBD app and follow its device-pairing steps
• If multiple scanners were paired before, unpair old devices in Android Bluetooth settings

What live data can I monitor while driving?

When connected, the Panlong adapter streams live sensor readings to your app so you can watch parameters like engine RPM, coolant temperature, fuel trims and oxygen sensor voltages. Monitoring these live values helps confirm repairs and observe performance trends over time.

• Real-time RPM, speed, temperature, fuel system status and sensor voltages
• Graphing and logging available through many compatible apps
• Useful for pre- and post-repair verification and fuel performance checks

Who is this for: The Panlong Bluetooth OBD2 Scanner is ideal for car owners who want to understand fault codes and basic live data themselves, hobbyists who perform routine maintenance, and mechanics who need a lightweight, app-driven scanner for quick checks. If you own an Android device and drive a 1996-or-newer OBDII-compliant petrol or light-diesel vehicle, this adapter gives affordable, on-the-spot diagnostic access without complex equipment.
