Tips For Identifying A Failing Oil Sensor

Your engine oil is an essential component for lubrication and cooling in your car's engine. You need to have the right weight, pressure, and distribution to ensure that your engine is protected. If the pressure gauge is telling you that your oil pressure is too low, the problem could be the oil volume, but it could also be the oil pressure sensor. Here are a few signs that the problem you're dealing with is the pressure sensor instead of the oil itself.

Oil Pressure Gauge and Dipstick Don't Match

When the oil pressure light comes on, it's an indication that your car's oil pressure is too low. If the light comes on and the pressure gauge is reading low, the first thing you should do is check the oil on the dipstick. The dipstick clearly shows you the ideal fill level and the low oil level marks. If your oil level on the dipstick is within the ideal fill level, that's a key sign that your oil pressure gauge and low oil light are receiving a faulty signal from the oil pressure sensor.  The sensor will send inaccurate readings to the gauges when it is starting to go bad, so when the reading doesn't match the indicator lights, you should check the pressure sensor.

The Oil Pressure Gauge Shows No Reading

When the oil pressure sensor fails, it won't send any signal at all to the oil pressure gauge. If your oil pressure gauge is reading zero and you know that there's oil in the engine, that is a very clear indication that the oil pressure sensor has failed completely and needs to be replaced by an expert like those at Action  Transmission.

The Oil Pressure Gauge Fluctuates

Your oil pressure sensor should send a consistent reading to your oil pressure gauge because the oil levels don't fluctuate. If your oil pressure gauge is fluctuating frequently, such as going from normal to low rapidly when you're driving, that's a clear indication that the oil pressure sensor is not functioning the way that it should.

Blinking Low Oil Light

Some cars have a notification system for failing oil pressure sensors. The low oil warning light will blink when the sensor is failing, letting you know that the sensor needs to be replaced. Seeing the low oil light flash can be somewhat disturbing sometimes, and it may worry you because usually, a flashing warning light is an indication of serious trouble. In this case, though, it's just an indication that the sensor is failing.

About Me

Learning More About At-Home Auto Service I have never been an especially handy person, but a few years ago I decided that I needed to learn more about my vehicle. I was tired of always relying on someone else to fix things, so I began reading more and more about the process. I realized that there were a lot of things that I needed to do, so I began taking a little course on at-home auto service. I still have a lot to learn, but now I can at least go through and change my air filter and check my oil. Read this blog to learn more about auto service.
