7 Common Causes of Low Oil Pressure Light on Dashboard (How to Prevent & Fix Them)

Описание: Is your car's oil pressure light on even though you just topped off the oil? You're not alone! This video dives into the reasons why you might see a low oil pressure warning light even when your oil level looks good.

Understanding Oil Pressure
The oil pressure warning light is crucial - it signifies a drop in oil pressure below a safe limit, which can lead to serious engine damage. But it's different from the oil level light.

Potential Culprits:
Faulty Oil Pressure Sensor: This sensor can malfunction and send incorrect signals, triggering the light despite normal pressure. You can check for blockages, leaks, or faulty wiring.
Failing Oil Pump: The pump ensures proper oil circulation. If it fails, oil pressure drops even with a full reservoir. Look for issues with the pressure relief valve or worn internal components.
Clogged Oil Pickup Tube: A blocked tube prevents oil from reaching the pump, causing low pressure. Inspect the tube and screen for debris.
Clogged Oil Filter: A clogged filter makes the pump work harder, reducing pressure downstream. Replace the filter regularly.
Excessive Engine Wear: High-mileage engines may have increased clearances between parts, reducing pressure. This can involve worn bearings or blockages in oil galleries.

Fixes & Maintenance:
Consult your car's manual for the correct oil viscosity. Wrong oil can affect pressure.
Consider flushing the engine oil system to remove debris if you suspect blockages.
