Setup and usage

After trying out OBD Fusion for a few weeks, we are quite satisfied with the results. The setup process is a breeze, and it only took me a few minutes to get everything fired up. We were able to diagnose faulty sensors and emission problems in a matter of seconds.

You can also set up the app for custom monitoring for specific functions. You can not only use OBD Fusion for reading generic PID codes but also manufacturer-specific ones. Generating a full diagnostic report takes only a few seconds, and you can also bring up freeze frame data within the app.

Vehicle diagnostics

You can use OBD Fusion for diagnostics on any car that is OBD2-complaint or supports EOBD. You can always check if your vehicle is OBD compliant online before investing in the app.

Scanning tools

As long as you have an appropriate scanning tool to use OBD Fusion, you will be able to get full use of the software. We recommend avoiding fake ELM products and rely on genuine adapters only. For recommendations, you can check out the compatible adapters in our review.

Trouble Codes: OBD Fusion can scan all known trouble codes by checking your MIL/CEL. You also get a real-time dashboard display feature to check trouble codes and monitor other key functions.

Fuel economy monitor

 You can monitor your fuel economy using OBD Fusion and get details on distance traveled fuel usage and fuel consumption. The app also offers built-in PIDs for some vehicles to monitor transmission or oil temperature issues.

OBD Fusion is excellent for both beginners and veterans. The customizable dashboard is something all OBD apps should implement. Seeing just what you need is very helpful when you are trying to fix a problem in your car.

It is also an excellent app for monitoring various engine systems to ensure everything is functioning smoothly.

The Maps feature is also a reliable add-on if you want to double up the app as your GPS companion. Another feature we like about the OBD Fusion app is emission testing.

It also helps mechanics with diagnostics and fixing commonplace car problems.

  1. Hi Tim!
    I enjoyed your article about the OBD Fusion app (iOS for me) and appropriate adapters to use.

    1) Would the appropriate pairing and purchase of additional OBD Fusion add-ons enable me to troubleshoot and diagnose a 2011 Toyota TPMS system also? (I liked it when you could put a jumper on the appropriate DLC3 terminals to read your problem!)
    2) Is there a license purchase required also?
    3) Is OBD Fusion/Veepeak the best hardware/app combo for this?
