• Use wire to control throttle body operation.

• Use the electronic motor to control the accelerator pedal.

• Use an electronic position sensor connected to the accelerator pedal.

What is the purpose of the fuel pressure inspection of the Engine Management System (EMS)?

• To ensure fuel does not leak.

• To ensure vehicle in good condition

• To ensure fuel supply working properly

• To keep the fuel pressure working properly

Which of the following are the advantages of using an engine management system?

• Low maintenance

• Reduce emissions.

• Ensure better fuel economy.

• Improve engine performance.

The other name for Electronic Control Unit (ECU) is Power Train Control Module (PCM). What are the symptoms of bad or malfunction PCM?

• Difficult to start.

• Engine stalling or misfiring

• Check engine light come out.

• Decrease engine performance.

What is the main function of Powertrain Control Module on the injection system?

• Received a signal from battery.

• To signify to driver the sensor condition

• For managed and control sensor working.

• Manage the engine's ignition system, fuel injection system and emission controls.

Which of the following are the components of the fuel injection system?

• Injector

• Relief valve

• Fuel pressure sensor

• High pressure fuel pump

The engine management system is basically a Power Train Control Module (PCM). Which of the following is an engine management system used in fuel system?

• Use the MAF sensor to control the volume fuel injected.

• Use an oxygen sensor in the exhaust to monitor the air to fuel ratio (AFR).

• Use Electronic control unit to control a series of actuators on an internal combustion engine.

• Use the fuel pressure regulator for regulating the pressure of the fuel flowing through the system.

To prevent serious injury and damage during performing fuel line pressure inspection, a technician always completes the “fuel line safety procedure”. which of the following procedure should be done "before service precaution"?

• Remove Fuel pump relay.

• Discharge static electricity.

• Disconnect battery connection.

• Release the fuel pressure in the fuel tank

Which of the following is a correct tool used to inspect fuel line pressure?

• Fuel indicator gauge

• Fuel pressure gauge

• High pressure gauge

• Fuel line pressure tester

What is the function of Mass Air Flow (MAF) Sensor?

• Measure the volume of air that enters the engine.

• Detect the amount of air intake airflow through the engine.

• Measure the volume air temperature before enters combustion chamber.

• Provides instant manifold pressure information to the engine's electronic control unit.
