OpenOBD

openOBD: Open Source OBD Diagnostic Tool

Open source program for reading sensor data from your car's on-board diagnostics port, monitoring engine RPM, vehicle speed, coolant temperature and more, while helping identify trouble codes.

What is OpenOBD?

openOBD is an open-source software program that allows owners and enthusiasts to tap into their vehicle's onboard diagnostics (OBD) port and access data from the car's various sensors and systems. Using an OBD adapter connected via Bluetooth or cable, openOBD scans and monitors parameters like:

• Engine RPM
• Vehicle speed
• Coolant and intake air temperatures
• Throttle position
• Fuel trim levels
• Trouble codes that could indicate problems

With openOBD, users can keep an eye on their vehicle's vital signs, log data over time to spot irregularities, clear error codes, gauge performance modifications, and even graph telemetry overlays of their drives. It is a helpful tool for both average drivers and automotive hobbyists. The software runs on Windows, Linux and macOS.

While the OBD2 scanner built into openOBD provides a wealth of raw data, the app also interprets trouble codes and sensor readings into more digestible information. It allows live data views, system tests, trip logging, and customizable dashboards to monitor specifically what the user is most interested in. The open source nature means openOBD is free to use and can be improved by the open-source community over time.
