How Live Data Works
Live data from an OBD2 scanner shows real-time information from a vehicle. It helps users see how the car’s systems perform while driving.
This data includes engine speed, temperature, and sensor readings. The scanner connects to the car’s computer to get these details instantly.
Data Transmission
The OBD2 scanner talks to the vehicle’s Engine Control Unit (ECU) through a data link connector. This connection sends signals back and forth.
- The ECU collects data from sensors around the vehicle.
- The scanner requests specific information from the ECU.
- The ECU sends the data in small packets to the scanner.
- The scanner processes and displays the data on its screen.
Interpreting Parameters
Each live data parameter has a code and a value. These codes help identify the exact reading, like engine RPM or coolant temperature.
| Parameter | Description | Unit |
| RPM | Engine speed | Revolutions per minute |
| MAF | Air flow rate | Grams per second |
| ECT | Engine coolant temp | Degrees Celsius |
| TPS | Throttle position | Percentage |
Choosing The Right Scanner
Choosing the right live data OBD2 scanner helps you get accurate vehicle information. It saves time and makes car diagnostics easier.
Look for scanners that fit your vehicle and offer useful features. This guide explains what to check before buying one.
