How should the technician enter findings for an aftermarket turbocharger not approved by CARB?

• A. Enter Not CARB Approved under 'Fuel System.'
• B. Enter On Hold under 'Electrical.'
• C. Enter Approved under 'Emission'
• D. Enter Modified under 'Other Emission Related Components.'

Answer: (D)

When a vehicle has an aftermarket turbocharger that isn’t CARB-approved, you’re documenting a modification to the emission control system. The turbo affects how exhaust emissions are managed, so this isn’t a fuel-system or electrical issue. Therefore you should record it as Modified under Other Emission Related Components, signaling that the component changes the emission controls and isn’t CARB-approved. It wouldn’t be correct to label it as Not CARB Approved under Fuel System, On Hold under Electrical, or Approved under Emission, since those don’t accurately describe the nature of the finding.
