A “Low Enhanced” emissions inspection is required for most other vehicles, unless they are subject to the OBDII test or are exempt from all emissions inspections. This inspection is required for all vehicles with a model year below the lower limit of OBDII test range and that weigh 18,000 lbs. or less.
Each emissions inspection for gasoline-powered vehicles confirms the presence and connection of the vehicle’s required emissions control devices. This includes making sure that the vehicle’s gas cap is present, is in good condition, and fits properly.
The following emissions control devices are examined if the vehicle was originally manufactured with them:
- Catalytic converter (CAT)
- Exhaust gas recirculation valve (EGR)
- Positive crankcase ventilation system (PCV)
- Air injection system (AIS)
- Evaporative emissions control (EVAP)
- Fuel inlet restrictor (FIR)
- Thermostatic air cleaner (TAC)
