Suddenly, an engine oil pressure warning light or a low oil pressure reading appears on your dashboard. At that moment, the engine oil pressure warning should be the only thing on your mind.
Understanding the Oil Pressure Warning
The engine oil pressure warning is a crucial signal that should never be ignored. This warning light indicates that your engine’s lubrication system is not functioning properly.
Main Causes of Low Oil Pressure
Insufficient Oil Level
Low oil level is one of the most common causes. An oil leak or excessive oil consumption can lead to this problem.
Oil Pump Issues
A faulty oil pump can no longer ensure adequate oil circulation in the engine, causing a drop in pressure.
Degraded Engine Oil
Aging or poor-quality oil loses its lubricating properties and can cause pressure problems.
Oil Pressure Testing Methods
Several methods allow for precise diagnosis of oil pressure problems. These tests should be performed by a qualified professional.
Test with Mechanical Gauge
Using a mechanical gauge allows accurate measurement of the actual oil pressure in the circuit.
Pressure Sensor Verification
A faulty oil pressure sensor can send false warning signals to the dashboard.
Immediate Actions to Take
As soon as the warning light comes on, stop the vehicle in a safe place and immediately check the oil level. Do not continue driving with this warning light illuminated.
