    Study Notes

    EGR Valve Function

    • Reduces NOx gas production in the combustion chamber.

    GVWR Determination

    • Use the vehicle weight placard to find Gross Vehicle Weight Rating (GVWR).

    Valid Registration Requirements

    • Acceptable documents include a valid registration card, pink slip, or a printed copy from the PennDOT vehicle registration website.

    Two-Speed Idle Test

    • Vehicle is operated at idle between 400-1250 RPM and at 2250-2750 RPM (typically 2500 RPM).

    Composition of Gasoline

    • Gasoline is made up of hydrogen and carbon atoms.

    Harmful Vehicle Emissions

    • Primary emissions include Carbon Monoxide (CO), Hydrocarbons (HC), and Nitrogen Oxides (NOx).

    Emission Test Failure Procedure

    • Provide the customer with a signed Vehicle Inspection Report (VIR) and repair data form if they fail the emission test.

    Initial Emission Inspection Documentation

    • Valid registration is the only paperwork required from the customer.

    Visual & Anti-Tampering Check Components

    • Inspections cover the catalytic converter, gas cap/fuel inlet, air pump, EVAP system, EGR valve, and PCV valve.

    Wavier Issuance

    • Only certified emission repair technicians can issue a wavier.

    Motorcycle Emission Inspections

    • Motorcycles do not undergo emission inspections.

    • Injects small amounts of air into the exhaust to help control exhaust gases.

    ASM5015 Test Results

    • Acceptable outcomes are Pass, Fail, Invalid, or Aborted.

    Free Retest Period

    • Customers have 30 days to request a free retest at the same repair shop.

    Gas Cap Testing Requirement

    Diagnostic Gases

    • Carbon Dioxide (CO2) and Oxygen (O2) are used for diagnostic purposes.

    Wavier Documentation Requirements

    • Required documents include the initial test VIR, retest VIR for failure, receipts for all repairs and parts, data repair sheet, and sticker insurance report.

    Insurance Requirement for Emission Inspections

    • Insurance is not required to perform an emission inspection.

    Gas Cap Replacement Policy

    • Technicians can offer customers the option to replace a failed gas cap without violating the test-as-received policy.
