Question

The oil light on a vehicle stays on while the engine is running.

A says this could be caused by too much cam bearing clearance.
B says a grounded wire in the oil lamp warning lamp circuit could cause this

-A
-B
-Both
-Neither

Answer 1

A vehicle's oil light remaining lit while the engine runs could be due to excessive cam bearing clearance or a grounded wire in the oil lamp circuit, making both suggestions valid.

Step-by-step explanation:

When the oil light on a vehicle stays on while the engine is running, it typically indicates an issue with the vehicle's oil pressure.

Technician A suggests that this could be caused by too much cam bearing clearance, which can lead to a drop in oil pressure as the oil can escape more easily from the bearings than intended.

On the other hand, Technician B points to a potential electrical issue, such as a grounded wire in the oil lamp warning lamp circuit, which might cause the light to stay on regardless of the oil pressure. In this scenario, both Technician A and Technician B's suggestions could be valid reasons for the oil light indication.
