If you own a car and are familiar with the term OBD2, then you probably know how useful it is to diagnose issues with your vehicle. But did you know that the data extracted from your car’s OBD2 can also be used in mobile apps? In this article, we will discuss what data can be extracted from OBD2 and how it can be used in mobile apps.

What is OBD2?

OBD2 stands for On-Board Diagnostics 2. It is a system that is built into cars to monitor the performance of various components such as the engine, transmission, and emissions systems. The information gathered by the OBD2 system can be accessed using a diagnostic tool which is typically connected to the car’s OBD2 port.

What Data Can Be Extracted From OBD2?

The type of data that can be extracted from an OBD2 system depends on the make and model of your car. However, some common data points include:

  • Engine RPM: This indicates how fast the engine is spinning.
  • Vehicle speed: This shows how fast the vehicle is moving.
  • Fuel level: This indicates how much fuel is left in the tank.
  • Coolant temperature: This shows the temperature of the engine coolant.
  • Oxygen sensor readings: These readings show if there are any issues with fuel efficiency or emissions.

These are just a few examples of what data can be extracted from an OBD2 system. There are many other data points that can be accessed depending on your car’s make and model.

How Can This Data Be Used in Mobile Apps?

The data extracted from an OBD2 system can be used in a variety of mobile apps. For example:

  • Diagnostic Apps: These apps can read the data from your car’s OBD2 and provide you with information about any issues that are detected. This information can be used to diagnose problems before they become more serious.
  • Fuel Economy Apps: These apps use the data from your car’s OBD2 to calculate your fuel efficiency and provide you with tips on how to improve it.
  • Performance Monitoring Apps: These apps use the data from your car’s OBD2 to monitor your vehicle’s performance and provide you with real-time feedback on how you’re driving.

The Future of OBD2 Data in Mobile Apps

As cars become more connected, we can expect to see even more innovative uses of OBD2 data in mobile apps. For example, some automakers are already using this data to provide real-time traffic updates and weather information. In the future, we may even see autonomous vehicles that use OBD2 data to make decisions about driving conditions.


In conclusion, the data extracted from an OBD2 system can be incredibly useful both for diagnosing issues with your vehicle and for enhancing your overall driving experience. By using this data in mobile apps, we can gain valuable insights into our cars’ performance and make more informed decisions about how we drive.
