For a car to run smoothly, its engine parts need to be well-lubricated. Engine oil keeps everything running smoothly and avoids friction and damage.
But, you know, the engine oil pressure might drop for various reasons, which can lead to issues with the car’s performance and longevity.
This article will discuss the causes and symptoms of low engine oil pressure and ways to fix it. So keep read on.
What is Engine Oil Pressure?
If you’re not familiar with engine oil pressure, don’t worry. It’s a pretty simple concept to understand.
Engine oil pressure refers to the force that pushes the engine oil through the engine. The oil pump creates this force and is crucial for keeping an engine’s moving parts well-lubricated.
The ideal engine oil pressure typically ranges from 25 psi (pound per square inch) at idle to 60 psi at higher engine speeds. Maintaining this pressure is essential for efficient engine performance.
Causes of Low Engine Oil Pressure
There can be various reasons why your car’s engine oil pressure drops below the recommended levels. Some of the common causes include:
Low Engine Oil Level
The most common cause of low oil pressure is simply having an insufficient amount of engine oil. As you drive, the engine oil gets consumed and needs to be refilled regularly. If the engine oil level drops too low, it can result in a drop in engine oil pressure.
Faulty Oil Pump
The oil pump circulates engine oil throughout the engine. A faulty oil pump can fail to maintain the recommended engine oil pressure, leading to low-pressure levels.
Worn Engine Bearings
Engine bearings are responsible for reducing friction between moving parts in the engine. Over time, these bearings can wear out, resulting in a decrease in engine oil pressure.
Clogged Oil Filter
The oil filter is designed to arrest impurities from the engine oil and prevent them from entering the engine. If the oil filter gets clogged, it can restrict the oil flow, resulting in low engine oil pressure.
Symptoms of Low Engine Oil Pressure
If your car is experiencing low engine oil pressure, you may notice some warning signs that indicate a problem with the oil pressure. Some common symptoms include:
Dashboard Warning Light
Most modern cars have a dashboard warning light that indicates low oil pressure. If this light turns on, you must immediately check your engine oil level and pressure.
Engine Noise
Low engine oil pressure can increase friction between engine parts, resulting in loud ticking or knocking noises from the engine.
Poor Engine Performance
Insufficient lubrication can cause the engine to perform poorly, reducing power and acceleration.
Engine Overheating
Oil also helps cool the engine by reduce heat from critical components. Low oil pressure can lead to overheating and potentially cause severe damage to the engine.
Fixing Way of Low Engine Oil Pressure
If you’re experiencing any symptoms of low engine oil pressure, don’t panic. The problem can be fixed with the following steps:
Step 1: Check Engine Oil Level
The initial step in ensuring your vehicle’s engine runs smoothly is to check the engine oil level. This is crucial because oil is essential for lubricating the engine’s moving parts, reducing friction, and preventing damage.
If you find that the oil level is low, adding the recommended type and amount of oil specified for your vehicle is essential. This will help bring the oil level back up to the proper mark on the dipstick, ensuring your engine is well-protected and operates efficiently.
Step 2: Replace Faulty Oil Pump
If the engine oil level is adequate but still experiencing low pressure, it could be due to a faulty oil pump. In this case, the only solution is to replace the oil pump with a new one.
Step 3: Inspect and Replace Worn Engine Bearings
Worn engine bearings can also lead to low oil pressure. If necessary, they should be inspected and replaced to ensure proper lubrication and engine performance.
Step 4: Change Clogged Oil Filter
The oil filter must be replaced for proper oil flow if it is clogged. This will help maintain adequate engine oil pressure and prevent damage to the engine.
Low engine oil pressure can be a cause of concern, but it can be easily fixed with timely action and maintenance.
How to Prevent Low Engine Oil Pressure?
If you want to prevent low engine oil pressure in your vehicle, here are a few tips to keep in mind:
- Regularly inspect your engine oil level and top it off if necessary.
- Follow the recommended oil change duration for your vehicle.
- Inspect and replace worn engine bearings regularly.
- Always use the recommended type and grade of engine oil for your vehicle.
- Keep an eye on the dashboard warning lights and address any issues immediately.
Following these preventative measures ensures that your engine oil pressure remains at the recommended levels, keeping your car running smoothly and efficiently.
Causes and Fixing way of High Engine Oil Pressure
While low engine oil pressure is a cause for concern, high engine oil pressure can also be problematic. Some possible causes and ways to fix them include:
- Excess engine oil can cause high pressure; remedy this by draining the surplus and refilling to the recommended level.
- A clogged or damaged oil passage can restrict oil flow, leading to high pressure. This issue can be fixed by cleaning or replacing any clogged parts.
- A faulty oil pressure relief valve can also produce high engine oil pressure. It should be replaced to prevent further damage.
How to Check Engine Oil Pressure Sensor Ok or Not?
The oil pressure sensor monitors the engine oil pressure and sends signals to the dashboard warning light. If you suspect that your oil pressure sensor may not be functioning correctly, here are some steps to check its condition:
- Use a multimeter to test the oil pressure sensor’s resistance. A reading of 0 ohms indicates a short circuit, while an infinite reading indicates an open circuit. Both of these conditions require the sensor to be replaced.
- Check the oil pressure sensor’s electrical connections for corrosion or damage. If necessary, clean or replace them.
- Use a mechanical gauge to measure the correct engine oil pressure and compare it to the readings on your dashboard. If they do not match, it could indicate a faulty sensor.
- Consult a mechanic or refer to your vehicle’s manual for specific testing and diagnostic procedures for the oil pressure sensor.
It’s essential to regularly checking the condition of your oil pressure sensor, as it plays a crucial role in maintaining the good health of your engine. If you suspect any issues, address them promptly to prevent further damage.
What are the Main Symptoms of a Faulty Oil Pressure Sensor?
Some common symptoms of a bad oil pressure sensor include:
- Dashboard warning light illuminating, indicating low oil pressure even when the engine oil level is normal.
- Inaccurate readings on the oil pressure gauge.
- An illuminated check engine light.
- Engine stalling or misfiring due to incorrect oil pressure readings.
If you experience any of these symptoms, it is important to get your oil pressure sensor checked and replaced if necessary. Ignoring a faulty sensor can lead to severe engine damage and costly repairs.
FAQs on Low Engine Oil Pressure
Q: What should I do if the low oil pressure warning light turns on?
Ans: Stop driving immediately, check your engine oil level and top it off if necessary. If the warning light persists, consult a mechanic.
