Symptoms of a Bad Oil Pressure Sensor and Replacement Cost

(Updated on April 10, 2020)

Oil is what lubricates the parts and components of a vehicle’s engine. 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.

Top 3 Symptoms

If you have an oil pressure sensor that is not working correctly, then your engine may suffer the consequences because it won’t get the proper amount of oil flowing into it. Below are the top 3 symptoms you can expect to see when there is a bad oil pressure sensor in your vehicle.

  1. Blinking Oil Pressure Light – If you see the oil pressure light blinking constantly and not staying consistently on or consistently off, then this is an early warning sign that your oil pressure sensor is about to go out. This is something you do not want to let go on for very long because you need to know that correct amount of oil pressure that you have. If you end up with low oil in your vehicle and you don’t know it, this could severely damage your engine. Therefore, never let this go to chance. Replace the oil pressure sensor right away.
  2. Oil Pressure Light Turns On – If the oil pressure light in your dashboard turns on and stays on, the first thing you might think is that you have a low level of oil in your vehicle. So naturally, you’ll want to check how much oil you have in your engine and make sure that it is at the proper level. If you find the oil level to be normal while your oil pressure light is still on, then it must be a problem with your oil pressure sensor. If you don’t get this problem taken care of soon, then it could lead to a blinking oil pressure light and then eventually wrong readings from the oil pressure gauge.
  3. Oil Pressure Gauge is Wrong – If you have an older vehicle, then it likely has a mechanical oil gauge in it which determines the oil pressure. If the gauge reading shows “0” and yet, your oil levels are completely normal, then it must mean that your oil pressure sensor is bad. However, if you’re like most people then you’re driving a modern car made within the last 10 years. The oil pressure gauge in a modern car communicates with the oil pressure sensor through an electronic signal. If you have a bad oil pressure sensor in a modern vehicle, then your oil pressure gauge could show strange readings or it could show that you have full oil pressure or zero oil pressure.
