Troubleshooting a Faulty Oil Pressure Sensor

bad oil pressure switch symptoms

How do you know if you have a bad oil pressure switch? Here are 3 common symptoms to look for diagnosing a faulty oil pressure sensor.


An oil sending unit is a sensor that measures oil pressure in the engine. If you are driving and your oil pressure warning light comes on stop immediately. Have a mechinic check your oil level and pressure. If your level and oil pressure are both ok it may just be a bad sending unit that needs to be replaced. If you are having issues with your oil sending unit the oil pressure light in your dash will come on.

That way, there is less friction inside of the engine. The hardest part is figuring out the amount of oil passing through the engine. This is where the oil pressure sensor comes in handy because it can detect when there is low oil pressure in the engine. Since the oil pressure sensor is connected to the oil pressure gauge and vehicle computer, it needs to work properly so that the computer can make sure the correct amount of oil is flowing into the engine. Below are the top 3 symptoms you can expect to see when there is a bad oil pressure sensor in your vehicle. The good news is that the replacement cost of an oil pressure sensor is cheap for the average vehicle.

The oil pressure is what sustains the oil flow inside of your internal combustion engine. As you know, the engine is comprised of several moving components. Many of these components create friction because they rub against each other. This friction generates heat which must be cooled down. The benefit of engine oil is that it cools and lubricates these components to reduce the heat and keep them running smoothly. As long as the oil pressure does not diminish, the oil can continue to benefit the engine in this way.

Maintaining proper oil pressure is vital to keeping an engine running. Rapidly moving metal surfaces produce lots of heat and friction and require constant lubrication to prevent damage to individual parts and the engine as a whole. The oil pressure sensor assumes the role of monitoring this internal pressure and sending a signal to the oil pressure gauge on your dash, alerting you immediately if there is a problem. This gives the driver time to pull over and assess the problem before costly repairs become necessary. Considering the important part they play in keeping your engine intact, how can you tell if an oil pressure sensor is failing?

It is much important to maintain proper oil pressure to keep your car engine running smoothly, and to maintain proper oil pressure, you need to ensure that oil change is done at correct intervals. It is the oil pressure sensor, which monitors the oil pressure and helps you to understand the internal pressure by sending a signal to the pressure gauge on the dashboard. This will let you know immediately if there is a problem. The Warning Light If you find that the oil pressure warning light on the dashboard is on, you will need to pay immediate attention. Even if you know that pressure sensor is bad, you will need to check the vehicle. If the oil dipstick shows that there is an adequate amount of engine oil and the engine runs smooth and quiet, the bad sensor might be resulting in the light.
