Questions And Answers Graded A+
Customer brings in a vehicle with wet tires for smog check inspection. What is the proper drying methods? Drive the vehicle on the BAR-97 dynamometer at approximately 25-30 mph until the tires are dry. During smog check inspection the technician noticed smoke coming out of the hood caused by oil leak from the head gasket dripped down to the exhaust. What should the inspector do next? Stop the inspection immediately due to safety hazard. During a smog check inspection the inspector smells fuel but there is no sign of fuel leak. What should the inspector do next? Do not continue with the smog check. Instead, thoroughly inspect the fuel system components, including the fuel lines, fuel rail, injectors, fuel tank, and filler neck. During a smog check inspection the inspector noticed a catback exhaust without EO installed on the vehicle. What should the technician do next? Cat-back exhaust systems (everything downstream of the catalytic converter, such as mufflers, resonators, and tailpipes) are not emission-control devices.
They do not require an Executive Order (EO) from the Air Resources Board (ARB). Pass the visual inspection and continue with the Smog Check. During a smog inspection on a diesel truck, the inspector noticed an additional catalytic converter to the muffler. What should the technician do next? For diesel-powered vehicles, the inspector must confirm that all emission-control components are present and unmodified. An additional catalytic converter (not originally part of the manufacturer’s configuration) is considered an emissions-related modification. If an extra CAT has been added without an EO, it is tamper During smog inspection the inspector noticed the vehicles license plate is from Utah out of state of California. What should the technician do next? Out-of-state vehicles must first go through DMV before a California Smog Check can be performed. During smog check inspection the inspector noticed the vehicle has an additional fuel filter without an EO number. What should the technician do next?
What are the two types of Acceleration Simulation mode tests? 50/15 and 25/25 test What does DAD stand for? Data acquisition device Smog check program divides the state into 3 areas determined by the air quality.. what are they? Enhanced, Basic, and Change of Ownership Biennial smog checks are required in which program area? Enhanced areas ( these areas do not meet federal or state air quality standards for ozone and carbon monoxide) If the VIN on the vehicle doesn't match the registration documents what should the inspector do? Use the VIN on the vehicle to inform the customer that it doesn't match the registration document. Refer customer to DMV Customer comes in for a smog check inspection for change of ownership and notifies the technician that the previous owner did smog and passed 3 weeks ago. What should the technician do next?
explain that a new smog check is required for the change of ownership, regardless of a recent pass, and perform the inspection During smog check inspection the inspector noticed the o2 wire is extended. What should the inspector do next? The inspector should fail the vehicle and document the extended O2 sensor wire because this is considered a tampering violation, and the vehicle will not pass the inspection During a smog check inspection the inspector notice the PCV hose is extended. What should the inspector do next? The inspector should fail the vehicle because an extended PCV hose is a form of tampering and can cause a vacuum leak, violating smog check requirements During smog check inspection the inspector noticed the pcv hose was replaced with a fuel hose. What should the inspector do next? The inspector must fail the vehicle and record the tampering with the correct hose type as the reason.
