Where does Honda Accord VI computer detect the plug?

Honda Accord VI does not have a computer to check the plug. OBD is an on-board automatic diagnosis system, which can diagnose the vehicle state. Read the fault code through the OBD interface of the car, and then analyze and eliminate the fault code of the car. Maintenance personnel can read the fault code through special equipment of automobile factory, quickly locate the fault problem, facilitate vehicle maintenance and greatly shorten the manual diagnosis time. The following is an introduction about OBD. 1, OBD real-time monitoring includes EGR, engine, particulate trap, catalytic converter, oxygen sensor, emission regulation system, fuel system and other systems and components. Such as intake manifold pressure, intake air temperature, air flow rate, throttle position, oxygen sensor voltage, fuel pressure, etc. 2. The original intention of 2.OBD is to monitor whether the vehicle exceeds the exhaust emission standard at any time according to the engine operation. The general function is to monitor the emission-related components in real time and send the information to the automobile computer to judge whether the vehicle is running normally; 3.OBD system monitors whether the vehicle exceeds the standard at any time according to the engine operation, and gives a warning in time after exceeding the standard. When the system fails, the powertrain adjustment module (PCM) can save the fault information in the memory and read the fault code from PCM through a certain program when the fault light or engine warning light is on. According to the prompt of fault code, maintenance personnel can quickly and accurately determine the nature and location of the fault.
