Where is the OBD port located in the Accord?

The OBD port is generally located in the interior trim panel below the steering wheel, near the driver's knee area. The exact position may vary slightly depending on the vehicle model. OBD stands for On-Board Diagnostics, a system that monitors the engine's electronic control system and other functional modules of the vehicle in real-time during operation. This system continuously checks whether the vehicle's emissions exceed standards and issues an immediate warning if they do. When a fault occurs in the system, the Malfunction Indicator Lamp (MIL) or Check Engine warning light will illuminate, and the Powertrain Control Module (PCM) will store the fault information in memory. The fault codes can be retrieved from the PCM using specific procedures. Based on these fault codes, technicians can quickly and accurately identify the nature and location of the fault. To locate the OBD port in various vehicle models, first identify the OBD port position. The OBD port is a 16-pin female trapezoidal connector, and some models may have a protective cover over the OBD port. Common OBD port colors include black, white, or blue.
