Where is the OBD port located in a car?

[LeAnthony]

The OBD port in a car is located in different positions depending on the vehicle model. For most cars, the OBD port is found below the lower left side of the instrument panel. If it cannot be found there, you can check above the pedals or in front of the gear shift lever. The function of the OBD port is: the OBD system continuously monitors the vehicle's exhaust emissions from the engine's operating conditions and immediately issues a warning if the emissions exceed the standard. When a system malfunction occurs, the malfunction indicator light or engine warning light will illuminate, and the Powertrain Control Module (PCM) will store the fault information in memory. The fault code can be read from the PCM through a specific procedure. Based on the fault code, maintenance personnel can quickly and accurately determine the nature and location of the fault.
