12.   Technician A says that the most efficient method of EVAP system leak detection is introducing smoke under low pressure from a machine specifically designed for this purpose. Technician B says that nitrogen gas pressurization uses nitrogen gas under a very low pressure (lower than 1 psi) in the fuel system; you listen for escaping air with amplified headphones. Who is correct?
     
A. Both Technicians A and B
B. Technician A
C. Technician B
D. Neither Technician A nor B
 
15.   Two technicians are discussing the evaporative emission monitor. Technician A says that serious monitor faults cause a blinking malfunction indicator lamp (MIL) or even an engine shutdown. Technician B says that the engine computer will run the EVAP monitor when fuel level is within 15 to 25 percent and the TP sensor position is between 9 and 10 percent. Who is correct?

Neither Technician A nor B

Explanation:

The evaporative emission monitor or Evaporaive Emission Control System EVAP System monitors enables the Power Control Module of the car to check fuel system leak integrity and the vapor consumption efficiency during engine combustion

It is a requirement of EPA on cars to check the emission of smug forming evaporates from cars

Serious monitor faults can cause the turning on of the check engine lights and the vehicle will not pass OBD II test, but it will not lead to engine shutdown

It runs when the engine is 15 to 85% full and the TP sensor is between 9% and 35%.

Therefore, the correct option is that neither Technician A nor B are correct.
