What should a technician do if an aftermarket turbocharger has no Executive Order number?

• A. The vehicle shall fail the visual inspection as the part cannot be confirmed to be approved for the vehicle.
• B. Accept the turbocharger as approved without EO.
• C. Proceed with testing but mark EO as unknown.
• D. Remove the turbocharger before testing.

Answer: (A)

In California, parts that affect emissions must have a CARB Executive Order (EO) number to prove they are approved for use on street vehicles. During the visual inspection, the inspector looks for that EO and verifies the part is authorized for the specific vehicle. If the aftermarket turbocharger has no EO or cannot be confirmed as approved for the vehicle, there is no way to verify its compliance, so the part cannot be deemed legal for use. Because the part’s approval status is unknown, the proper action is to fail the visual inspection rather than certify the vehicle or proceed with testing. Accepting it as approved without an EO would ignore the required authorization. Proceeding with testing while EO is unknown isn’t allowed because testing relies on known, approved configurations. Removing the turbocharger before testing isn’t the standard fix for an unverified part and would defeat the purpose of the visual check. The safe, correct course is to fail the visual inspection when the part cannot be confirmed as CARB-approved.
