How to Conduct Annual Inspection for Vehicles Without OBD?

[WalterMarie]

Vehicles without OBD cannot undergo annual inspection. According to the new regulations, OBD testing has been added to vehicle inspections. If the data obtained from the OBD is abnormal, it will directly affect the annual inspection of the vehicle, regardless of whether the exhaust emission test is passed or not. It is highly likely that the vehicle will fail the annual inspection due to abnormal OBD data. Here is some relevant information about vehicle OBD: 1. The OBD system continuously monitors the engine's operating condition to check if the vehicle's exhaust emissions exceed the standard. If they do, it will immediately issue a warning. 2. OBD testing requires the cooperation of numerous sensors. However, sometimes the issue may not be with the vehicle itself but rather with a malfunctioning sensor causing false OBD alerts. 3. If you find that the OBD fault code appears intermittently, it is likely due to a damaged sensor. In this case, replacing the sensor should resolve the issue. Additionally, after clearing the OBD fault code, the vehicle should be driven sufficiently before undergoing inspection at the vehicle management office.
