Where is the OBD interface located in a sedan?

The OBD interface in a sedan is located in: 1. The lower left side of the dashboard; 2. Above the pedal; 3. In front of the gear shift lever. The working principle of the OBD interface is: it continuously monitors the engine's operating conditions to check if the vehicle's exhaust exceeds the standard. Once it exceeds the standard, a warning will be issued immediately. When a system failure occurs, the fault light or check engine warning light will illuminate, and the powertrain control module will store the fault information in the memory. Through a certain program, the fault code can be read from the PCM. The devices detected by the OBD interface include: engine, catalytic converter, particulate trap, oxygen sensor, emission control system, fuel system, EGR.
I've been driving for over ten years, and the OBD port in most common sedans is typically located in the dashboard area below the steering wheel. Just take a look under the steering wheel, near the knee area, and you'll find a small square slot or cover. Most car models follow this design for easy access to connect diagnostic tools and check fault codes, like when the engine light comes on. The location is pretty standard, but imported cars or niche brands might have slight variations—some may hide it behind the glove compartment. If you can't find it, check the latter part of the owner's manual or ask a mechanic friend for help. Avoid forcing it open yourself to prevent damaging the wiring. Overall, it's highly practical, and remember its proximity to the driver's seat is for quick maintenance access.
