Using state-certified equipment, we verify that all measurable outputs align with California requirements. Our inspection process follows approved protocols to ensure accuracy, consistency, and regulatory compliance for gas-powered vehicles requiring certification.

OBD-II Diagnostic Testing

We perform onboard diagnostics testing to confirm that the vehicle’s computer systems report accurate emissions data. This process identifies stored fault codes, readiness monitors, and system performance indicators. Proper OBD-II analysis ensures that electronic emissions controls function correctly before certification is issued under state guidelines.

Visual and Functional Component Inspection

 We visually and functionally inspect emissions-related components for tampering, wear, or improper installation. This includes hoses, sensors, and emission control devices required by California law. The inspection verifies that factory-designed systems remain intact and operational, supporting both compliance and long-term vehicle reliability.

Tailpipe Emissions Analysis 

We measure exhaust output to evaluate hydrocarbon, carbon monoxide, and nitrogen oxide levels. This testing confirms that emissions fall within permissible limits established by state authorities. Accurate tailpipe analysis is essential for identifying combustion inefficiencies and ensuring lawful operation throughout regulated counties.

Pre-Inspection Readiness Checks

We assess vehicle readiness status before formal testing begins. This step helps confirm that onboard systems have completed required drive cycles and are prepared for evaluation. Readiness checks reduce unnecessary failures and provide clarity regarding whether the vehicle meets testing prerequisites.
