the bypass system to send unfiltered oil
, resulting in rapid wear of the camshaft also known as the “cam effect” which in turn can produce knocking sounds in the engine.

. After the readings fall out of specification, a warning light is set. The faster this sensor can be replaced, the less stress you will have regarding the oil levels in your vehicle.
Will a car start with a bad oil pump?
Vehicle won't start

Where is the oil pump located?
Your vehicle's oil pump is typically located
inside your vehicle's oil pan
. It generally sits towards the top of the pan and uses a pickup tube to take oil from the pan and push it through the engine. In some engines, it is also located around the crankshaft at the front of it.
Will a bad oil pump make a knocking noise?
Low oil pressure can be caused by a clogged line, a bad pump, or a clogged filter.
The low oil pressure would rob the engine of the oil it needs and produce a knocking sound
. The oil pressure can be tested with a gauge. If the issue is mechanical, it may be a piston or valve issue.

Can a oil change stop engine knocking?
Adding more oil
will
make the noise go away, but it won't solve the underlying cause of the noisy engine – the oil leak.
Is it normal for oil pressure to drop at idle?
Low oil pressure at idle only
, will most often mean that the engine is low on oil. As more power is applied to the engine via acceleration, the pressure builds up inside the engine. Thereby causing the pressure to read as “normal”. … A defective oil pump can also lead to low oil pressure at idle.
