A scan tool PID (Parameter Identification) is a code used by OBD-II (On-Board Diagnostics) scan tools to request specific real-time data from a vehicle's onboard computer. PIDs are essential for diagnosing vehicle issues and monitoring performance. They provide access to detailed information such as:
- Engine RPM
- Coolant Temperature
- Oxygen Sensor Readings
- Fuel Trim Values
- Vehicle Speed
Each PID corresponds to a specific data point within the vehicle's system. By reading these parameters, technicians and DIY enthusiasts can identify malfunctions, monitor performance, and ensure the vehicle operates efficiently.
