OBD in China V vehicles refers to the On-Board Diagnostics system. OBD monitors the engine's operating conditions to check if the vehicle's exhaust emissions exceed standards, and it will issue an alert immediately if they do. The function of the On-Board Diagnostics system is to automatically monitor the engine's operating status and diagnose the working conditions of other vehicle components. When a fault occurs in any system of the vehicle, the fault indicator light will trigger an alert. The OBD device can simultaneously monitor multiple systems and components in the vehicle, including the engine, catalytic converter, particulate filter, oxygen sensor, emission control system, and fuel system.

Off-road vehicles generally have strong power output, which can compensate for power loss due to oxygen deficiency.
