Ignition review 5

This is an example of a:

• Carbon fouled plug

• Normal looking plug

• Wet fouled plug

• Plug that is too hot

This is an example of a/an:

• Normal looking plug

• Over-heated plug

• Carbon fouled plug

• Plug that is too cold

Corona staining occurs due to:

• Electrostatic induction

• Electrostatic reduction

• Oil wicking up the porcelain

• Oil wicking through the coil boot

The maximum amount of voltage the VCMM can handle is _____ volts

• 20

• 100

• 60

• 35

What is needed to protect the Picoscope when measuring flyback voltage from the primary circuit?

• attenuator

• capacitor

• special leads

• special gloves

What fault is indicated by the pattern circled in red?

• Plug gap that is too small

• Too little system voltage

• Open secondary (open plug wire)

• Bad primary coil

If a component that is PCM driven is shorted, what will the PCM do to protect itself?

• Set a code

• Redirect the voltage somewhere else

• Turn off the circuit

• There is no protection

The monitor circuit inside the PCM is capable of detecting any fault that causes the coil to not fire correctly or at all, including resistance.

• True

• False

What could a lack of oscillations on a coil waveform indicate

• Coil is starting to fail internally

• Coil is operating correctly

• Problems in the secondary

• Problems in the spark plug

Are you able to access primary voltage on a 3 wire ignition system?

• Yes

• No
