Exam 6: Ignition System and Related Input Sensors Output Actuators Diagnosis

As the rpm of an engine is increased, the ignition spark occurs:

In a coil-on-plug system, each spark plug has its own ignition coil. What are the two different ways the ignition modules are placed in a coil-on-plug system?

The ignition system on many newer cars has no:

The coil-on-plug design allows for increased coil saturation time between cylinder firing.

The sensors that are an integral part of the ignition system are also an integral element in what monitor for OBD II systems?

What is the number of volts supplied to the coil primary winding?

A technician repaired a cold-start and hard-starting problem by replacing the secondary ignition wires and spark plugs. After the repair, the vehicle failed an emission test for high CO and HC levels. Technician A says a restriction in the fuel delivery system such as the fuel filter could be the problem. Technician B says that the engine oil could be contaminated with fuel. Who is correct?

What happens when the edge of a rotating blade moves into a Hall Effect switch and what happens when the edge of the rotating blade exits the Hall Effect switch?

What is the term for the period of time when current flows through the primary windings of a coil to increase the magnetic field generated?

The vehicle manufacturer specification for spark plug heat range can be changed.

A higher than normal firing line voltage could be caused by a low secondary ignition resistance.

Technician A says that the Hall Effect sensor produces a digital square wave voltage signal. Technician B says that the Hall Effect sensor contains a permanent magnet on the outside of the rotating blades. Who is correct?

The primary current must flow long enough to:

Electronic ignition (EI) systems produce an average current flow across the spark plug electrodes of 1.5 milliseconds compared to about 1 millisecond in an older-type distributor ignition (DI) system. Why is this extra 0.5 millisecond of current flow in an EI system important?

The long-life platinum spark plugs have a designated service life of 50,000 miles (80,467 km).
