IMI LV07

Which type of sensors create a sine waveform

• reactive

• conductive

• Inductive

• reflective

Reorder the following diagnostic process

• Visual Inspection

• Confirm Fault

• Code Read/Live data

• Pull/physical test

• Electrical Test

Decreasing Injector pulse widths would

• allow more fuel

• allow less fuel

• allow multiple injections

• delay spark

Draw what an injector scope graph would look like

Which is most likely to cause excessive fuel consumption

• Leaking injectors

• Faulty temp sensor

• Faulty coil pack

• Blocked air filter

If any inconvenience occurs when working on a customers car what is the first step

(a)  

How are you getting on with assignments

How do you check for a broken wire?

• Ohm meter

• Resistance Test

• Current test

• Voltmeter

Which one of the following describes a method of improving volumetric efficiency

• Adjust spark time duration

• Increase valve length

• Use variable length intake manifolds

• Adjust injector pulse width

During a cylinder leakage test, a leaking inlet valve seat will be indicated by

• air bubbles in the cooling system

• a hissing noise heard from the oil filler cap

• air escaping from adjacent spark plug holes

• a hissing noise heard at the air cleaner flange
