The best OBD2 scanner for emissions testing can check readiness monitors, show incomplete or supported tests, and help you determine if your car will pass a smog check before heading to the testing station.

Most OBD2 scanners can show basic emissions readiness, but the best scanners for smog checks give you a detailed breakdown of which monitors are complete, incomplete, or unsupported.

An emissions OBD2 scanner helps you avoid failing a smog check by showing whether your vehicle’s systems are ready. This saves time, money, and hassle by ensuring your car meets emission standards.

The best emissions OBD2 scanner should include:

  • Emissions readiness / I/M monitor checks
  • Live data to spot issues in real time
  • Freeze frame data for failed tests
  • Compatibility with all OBD2-compliant vehicles

You do not need a professional OBD2 scanner, but we highly recommend that you check out Innova scanners. They clearly display I/M readiness monitors, including which systems are complete, incomplete, or unsupported—crucial for avoiding a failed smog test.

Many professionals use our tools due to how easy it is to use for SMOG purposes.

All Innova scanners are compatible with any OBDII compliant vehicle manufactured after 1996 or newer. However, available features may vary depending on your specific vehicle.
