The OBD port, also known as the On-Board Diagnostics port, is typically located under the dashboard on the driver's side of the vehicle. This port serves as the connection point for an OBD scanner to communicate with the car's computer system. The OBD system within the vehicle tracks various data such as speed, mileage, and emissions, enabling the Engine Control Unit (ECU) to optimize the car's functions for efficiency. Additionally, the ECU triggers the check engine light to alert drivers of any detected faults in the vehicle. The average cost for an OBD diagnosis is usually between $45 and $65, though prices may vary slightly based on the service provider you choose for your OBD inspection.
