Level 2 Motor Vehicle Engine Faults

One probable cause of an engine misfires at all engine speeds is:

• blocked air filter

• defective coil

• defective knock sensor

• a low resistance plug lead

One probable cause of the discharge temperature being lower than normal when carrying out a air conditioning system check is:

• the expansion valve open too long

• kinks in the system pipes

• an excessive amount of refrigerant

• a frozen evaporator

In relation to a vehicle, what does the abbreviation 'VIN' mean?

• Vehicle Information Number

• Vehicle Identification Number

• Vehicle Interpretation Number

• Vehicle Introduction Number

Why is it important to report any delays in completing a vehicle repair by the promised deadline to your supervisor?

• So the customer can be informed

• So the labour rate can be increased

• To ensure your bonus is not affected

• So they can increase productivity

Which one of the following faults would most likely highlight a defective coolant temperature sensor?

• Engine juddering and blue smoke

• Excessively increased engine power

• Engine knocking when under load

• Excessive fuel consumption

By increasing the fuel injector pulse width this in turn will:

• lower the injector resistance

• increase the injector resistance

• inject less fuel

• inject more fuel

A hot wire air flow sensor measures:

• air temperature

• throttle position

• air pressure

• air flow mass

An internal combustion engine that can compress the intake air greater than atmospheric pressure:

• is turbo-charged

• has a high compression ratio

• incorporates variable valve timing

• is of two-stroke design

What is the meaning of the abbreviation COSHH?

• Control Of Systems Hazardous to Health

• Company Organised Systems for Health & Hazards

• Company Obligations & Systems for Health & Hazards

• Control Of Substances Hazardous to Health

A higher voltage is required to cause a spark at the spark plug gap when the:

• gap is reduced

• gap is increased

• ignition is retarded

• cylinder pressure is low
