An oil pressure sensor is also known as an oil pressure switch, is established to control the oil level in the engine. Its major function is to report to a connected computer, which turns on the oil pressure warning light. But will my car run without oil pressure sensor?
However, your car can drive without an oil pressure sensor, but it’s very risky. If you remove the oil pressure sensor, the check engine light or the oil pressure engine light will continuously remain shimmering on your dashboard.

Will My Car Run Without Oil Pressure Sensor?
If you’re running an old car, even when with a poor oil pressure sensor, your car is going to start, and surely, you can drive.
On the other hand, most newer cars are complicated. The oil pressure sensor is attached to a computer.
If the sensor is discarded, the computer would scan that your engine has no oil, and it could prevent your car from starting as a way of defending your engine from harmful destruction due to the absence of oil.
Well, It is not recommended to drive your vehicle without an oil pressure sensor because it could give rise to serious trauma that would push you for extra money.
What Would Happen When You Drive Without Oil Pressure Sensor?
If you drive without an oil pressure sensor, you’re leaving your engine at serious threat, and deadly damage. Because, when the oil pressure is poor, the warning light would appear on your dashboard.
You already know you got a poor sensor, and that’s why the warning light is on, you may not be too mindful to know when the oil in your engine goes low. When the oil in your engine is insufficient, it imposes the engine at huge risk.
Every part of an engine is meant to be often greased and the only way to keep them greased is by adding oil to the engine.
How To Know That Your Oil Pressure Sensor Is Bad?
We’ve collected a bunch of signs to help you out with your question:
1. The Warning Light
The most common and the only sign of a bad oil pressure sensor is the shimmering of the oil pressure warning on your car dashboard.
So, when these lights start shimmering, you should check your engine, and run troubleshooting to specify the actual reason why the light came on.
2. The Oil Light
Difficulties with the actual oil pressure in your car shouldn’t be discontinuous, thus a blinking oil light is the clearest sign that the sensor is stopped working. Although if you have a much older car, it might not have a reliable oil pressure light and rather might appear as the Check Engine light. But since not all engine lights on those cars are essential means there is something improper with your oil pressure.
It wouldn’t harm to check the oil points yourself, making sure it is proper and there are no weird sounds.
If your oil pressure sensor seems to be working, another reason is that your oil light may shimmer if the oil pressure is bad. This is noticeable but important to know.
Low pressure means that either the pump does not spread enough oil, or there just isn’t enough oil to spread. Oil is important to keep parts greased, so if your oil pressure is low, you should turn your engine off or visit a mechanic.
4. The Oil Pressure Gauge
Just like the oil light, your gauge shouldn’t be periodic, thus if you get a continual gauge study of either very high or absolute zero, your sensor could be to blame. Although it could be an internal short in the sensor, giving a constant high/zero reading, damage to the wiring, an oxidised plug, or barely an unplugged connection.
Before you assume anything, you should test the oil using a dipstick and listen to the engine. If you notice too much oil, remove it instantly, as too much oil causes low pressure due to foaming, which isn’t good for your car.
How To Replace The Oil Pressure Sensor?
Follow the below steps if you would like to replace your oil pressure sensor.
- Locate The Oil Pressure Sensor
- Unplug The Oil Pressure Sensor Electrical Connector.
- Remove The Oil Pressure Sensor
- Compare New Old Pressure Sensor
- Install The New Oil Pressure Sensor
- Re-apply The Electrical Connector
- Check If It Works
- Done
FAQ
Have a look at some frequently asked questions:
Q1. Is The Oil Pressure Switch Or Sensor The Same Thing?
The two parts are different in procedures but perform the same function.
Q2. How Long Does A Car Run Without Oil Pressure?
Approximately 15 minutes.
Q3. Can Low Oil Cause Overheating?
A vehicle that’s low on oil tends to overheat because the oil removes from 75 to 80 % of the “waste heat” in your engine.
Conclusion
You should craft a maintenance plan and stick to it; also, you need to pay attention to the minor components that make your car move; components like the fuel and oil filters, pressure valves and switches, and other parts that are typically neglected by many drivers.
Will my run without oil pressure sensor? Summarily, if you’ve got a new model car, you may not be able to start the car if you’ve got a bad oil pressure sensor.
But older cars may start and drive; however, that’s a big risk that could result in costlier damages; always take precautions as regards your car engine.
