What is the Low Oil Level Sensor all about?

The vital role of the low oil level sensor is protecting your engine from friction as well as wear and tear. You need to have the right amount of oil in the engine at all times or the friction and heat will severely lower the longevity of your engine components. Today, most cars come with an oil level sensing system that determines how much oil is in the pan and transfers the information to the car’s computer. If the level is too low, the computer turns on the Low Engine Oil light on the dash, warning the driver of the problem.

The low oil level sensor is attached to a float type device in the oil pan. It measures the amount of oil present in the pan during operation. Depending on the position of the float, the sensor knows how much oil is present and sends the data to the computer. The computer compares that information with the preprogrammed readings from the automaker and determines if it’s sufficient.

Keep in mind:

  • The Low Engine Oil light is located in the dash gauge cluster and should come on for a few seconds after you initially crank the engine.
  • If you get erratic warning lights in the dash, but the level of the oil in your pan is normal, the low oil level sensor is likely the culprit.
  • The low oil level sensor is not an included part of any normal inspection.

How it's done:

  • The vehicle is lifted and supported on jack stands and the oil and filter are removed
  • The defective low oil level sensor is removed
  • The new low oil level sensor is installed
  • The vehicle is removed from jack stands then oil and filter installed
  • The vehicle is started and checked for oil leaks and level operation

Our recommendation:

Maintaining the right oil level in your engine at all times is absolutely crucial. If the low oil level sensor in your engine is malfunctioning, you have no way to determine if there’s a problem. If the oil level does drop too low, there’s the potential for significant damage. Have one of our expert mechanics diagnose the system if you suspect a problem.

What common symptoms indicate you may need to replace the Low Oil Level Sensor?

  • Low Engine Oil warning light on in the dash, even when the level is correct
  • Erratic warning lights when level is full
  • Light comes on and stays on when oil is full

How important is this service?

While the low oil level sensor isn’t critical to engine operation, it is an important safeguard. If you’re experiencing any problems with the light and suspect that the sensor is to blame, have our expert mechanics diagnose the problem.

BMW 645Ci V8-4.4L - Pre-purchase Car Inspection - Ontario, California
He was caught in traffic but made sure to call prior to arrival and kept in touch till he arrived. It was raining but he did a thorough review of the car. He got he on the phone before he left the dealership and walked me through the findings. I asked him to do a couple more items and he gladly obliged. I was very happy with the service.

BMW 645Ci V8-4.4L - Oil Change - Las Vegas, Nevada
He seems professional. I paid for the lights to be addressed and they are all still on including a low engine oil light. He said he would return to check it out further after his next appointment but I did not hear back from him. I was told by BMW that the power steering fluid needs to be drained, flushed and refilled. He sucked it out with a hose twice and this will not ensure that the oil that was accidentally placed in there would be completely removed. I am no mechanic but I am going off of what BMW told me. I wanted to get a lot more work done. I want all the lights to be addressed and fixed so I started with the check engine lights to be looked at and not just reset. I want everything to be fixed. Thank you

Pete was here on time, very knowledgeable of my BMW, and made me feel comfortable and confident that he would make the repairs correctly. I also was very impressed with his honesty, and he exceeded my expectations. I am very pleased and will call on him (you) next time. I will definitely recommend his service to friends.
