California Smog Check Inspector Practice Test

Which vehicles are subject to OIS inspections with OBDII?

1. Only 2005 and newer gasoline vehicles

2. 2000 and newer gasoline and hybrid vehicles plus 1998 and newer diesel vehicles under 14,000 GVWR

3. All diesel vehicles regardless of age

4. Electric vehicles with less than 10,000 miles

The correct answer is: 2000 and newer gasoline and hybrid vehicles plus 1998 and newer diesel vehicles under 14,000 GVWR

The correct answer focuses on the specific requirements for Onboard Diagnostic System (OIS) inspections with OBDII (Onboard Diagnostics II). Under California regulations, vehicles that fall into the criteria specified in the correct answer include: 1. Gasoline vehicles manufactured from 2000 and newer. These vehicles are typically equipped with OBDII systems that monitor emissions and performance of the engine, ensuring compliance with environmental standards. 2. Hybrid vehicles that were also produced from 2000 and onwards share similar emissions monitoring systems as conventional gasoline vehicles, making them subject to the same inspection requirements under OBDII. 3. Diesel vehicles under 14,000 Gross Vehicle Weight Rating (GVWR) that were built from 1998 onward are included in this category. Although diesel engines operate differently than gasoline engines, the regulations require OBDII inspections for certain diesel vehicles based on their model year and weight class to ensure they meet emissions standards. This comprehensive approach allows for targeted emissions monitoring across a more extensive range of vehicle types, adapting to advancements in technology and variations in emissions systems. In contrast, other options either restrict the type of vehicles improperly to only certain years or exclude key vehicle types, such as hybrids or diesel vehicles, which face OBDII inspection
