Unlike basic code readers that only display fault codes, the AutoTruth Professional OBD2 Scanner helps you understand what's happening inside your vehicle with comprehensive diagnostic functions.

Read & Clear Check Engine Codes

Quickly retrieve generic (P0), manufacturer-specific (P1), and pending trouble codes. Clear codes and reset the Check Engine Light after repairs.

Live Data Stream

Monitor real-time engine performance, including:

  • Engine RPM
  • Vehicle Speed
  • Coolant Temperature
  • Fuel System Status
  • Short & Long-Term Fuel Trim
  • Oxygen Sensor Data
  • Intake Air Temperature
  • Mass Air Flow (MAF)
  • Engine Load
  • Battery Voltage

Perfect for diagnosing intermittent problems that don't always trigger warning lights.

I/M Readiness Test
