Here is how a smog test is performed here in the greater Las Vegas area:
Nevada uses On-Board Diagnostics (OBDII) testing for 1996 and newer light-duty gas vehicles.
The inspector will connect an analyzer to the OBD computer in your vehicle and read the data from the emission control systems.
A technician will visually check the following items on light duty gas powered vehicles older than 1996 and all 1968 and later model heavy duty gas powered vehicles:
- Secondary Air Injection System
- Exhaust Gas Re-circulation
- System Catalytic Converter(s)
- Fuel Inlet Restrictor
- Gas Cap
Diesel tests are run on a dynamometer using an opacity meter to read visible particulate emissions. You can find out more by clicking the button below.
