Question

1. two technicians are discussing a misfire on a vehicle. technician a says that a faulty ignition coil on a coil on plug ignition system will likely only cause a misfire on one cylinder. technician b states that in the case of a multi cylinder misfire the crankshaft position sensor may be the cause. who is correct?

a. technician a only
b. technician b only
c. both technicians
d. neither technician

Explanation:

• Technician A: In a coil - on - plug ignition system, each cylinder has its own ignition coil. So, a faulty ignition coil would only affect the cylinder it is connected to, causing a misfire on that single cylinder.
• Technician B: The crankshaft position sensor provides crucial information about the position and speed of the crankshaft. If it is malfunctioning, it can disrupt the ignition timing and fuel injection for multiple cylinders, leading to a multi - cylinder misfire.

Answer:

c. Both technicians
