Where is the diagnostic port on a 2001 Honda Accord?

It's located near the steering wheel. Here are the relevant details: Introduction: The sixth-generation Honda Accord does not have a diagnostic port. OBD (On-Board Diagnostics) is a vehicle self-diagnosis system that can monitor the vehicle's condition. By reading fault codes through the car's OBD interface, it helps analyze and clear vehicle fault codes. Mechanics use specialized manufacturer tools to read these codes for quick fault localization, significantly reducing manual diagnosis time. Real-time monitoring: Systems and components such as EGR, engine, particulate filter, catalytic converter, oxygen sensors, emission control systems, and fuel systems. Parameters monitored include intake manifold pressure, intake air temperature, air flow rate, throttle position, oxygen sensor voltage, fuel pressure, etc. The original purpose of OBD was to monitor whether a vehicle's emissions exceed standards through engine operation monitoring. Its primary function is real-time monitoring of emission-related components, sending information to the vehicle's computer to determine if the vehicle is operating normally. The OBD system continuously monitors whether the vehicle's emissions exceed standards during engine operation and will issue an immediate warning if they do. When a system fault occurs, the malfunction indicator light or check engine light will illuminate, and the Powertrain Control Module (PCM) will store the fault information in memory. Through specific procedures, these fault codes can be retrieved from the PCM. Based on these fault codes, mechanics can quickly and accurately determine the nature and location of the fault.
