Technician Asays a fuse will automatically reset after the cause of the overload is repaired. Technician B says when an overload occurs, the protection device creates an open. Who is correct?
An engine with DI ignition becomes harder to start as outside temperature drops. Below freezing, the engine will not start at all. Technician A says that the problem could be a faulty ignition coil. Technician B says that the coil wire may be bad. Who is right?
AC generator ground wires are usually braided ground straps. The condition of these wires is as important as the insulated wires because they carry the same current flow.
Two technicians are discussing electromagnetic induction. Technician A says that the induced voltage can be increased if the speed is increased between the conductor and the magnetic lines of force. Technician B says that the induced voltage can be increased by increasing the strength of the magnetic field. Which technician is correct?
Technician A says any type of valve guide can be used with any type of valve. Technician B says some guides are incompatible with stainless steel valves. Who is correct?
Technician A says that CAT I meter leads may be used to test HV system components as long as the DMM itself is rated CAT III. Technician B says that CAT IV test leads are clamp-on inductive type leads. Which technician is correct?
An oxygen sensor is being tested with a digital multimeter using the MIN/MAX function. The readings are: minimum = 78 mV; maximum = 932 mV; average = 442 mV. Technician A says that the engine is operating normally. Technician B says that the oxygen sensor is skewed too rich. Which technician is correct?
Technician A says that full hybrid electric vehicles need to be plugged into a standard AC electrical outlet to charge. Technician B says that the high voltage battery in an HEV uses a generator driven by the internal combustion engine for recharging. Which technician is correct?
Two technicians are discussing alternative fuels. Technician A says that biodiesel is produced from vegetable oil that is used as cooking oil. Technician B says that biodiesel is produced from refined natural gas. Who is correct?
Technician A says MSDS sheets are required for all chemicals used or stored on the premises. Technician B says the MSDS lists the protective clothing or equipment for that material. Who is correct?
Technician A says that fuel tank accident and rollover protection devices include check valves and inertia switches. Technician B says that most fuel lines are made of ABS plastic. Who is right?
Technician Asays air fills the rear chamber when brake application opens the air valve and closes the vacuum valve, and the front chamber is kept in vacuum. Technician B says when the brakes are held at midpoint, both valves are closed to trap vacuum and atmospheric pressure and keep the diaphragm in a balanced position. Who is correct?
Two technicians are discussing the Environmental Protection Agency (EPA). Technician A says the EPA was formed in the 1890's to address pollution from factories. Technician B says that the EPA met with early resistance in its efforts to protect the environment. Who is correct?
OBD-II equipped vehicles are required to turn on the malfunction indicator lamp if the system has detected an exhaust emission level that is ________ the FTP limit
Technician A says that during engine disassembly, all main and rod bearings should be kept in order in case they will be reused. Technician B says that there is no need to keep bearings in order if new parts are to be used. Who is right?
In an electronic air suspension system, what action is taken by the chassis control module if a command is received from the rear suspension sensor to lower the vehicle if the engine is running with a door open, and the control module receives a lower vehicle command from the height sensor?
