What does it mean when the low oil pressure light comes on?

Very likely tell you that you have low engine oil level. I surprised that you didnt kill engine driving like that. If oil level is ok then it may indicate low engine oil pressure. See mechanic.

Oil light is rather important it goes out if oil pressure is good comes on if oil pressure is low when it comes on damage is expected with continued operation like wearing of main bearings and pistons and cylinders can lead to a engine rebuild

this means a mechanical gauge test is required to check actual pressure warm idling if low below 20 psi then the oil pressure pump relief is stuck open or engine bearing are worn

It can mean one of two things. Either your oil level is too low, meaning more than 1 quart, or your pressure is too low. The first thing to do is check the oil level in the engine and top it up. If the light goes out after this then everything is okay. If the light stays on you should get the oil pressure checked with a mechanical guage to get an accurate reading.

Get this done as soon as possible. Manufacturers don't give you much room with these lights, when they come on you are very close to the engine meltdown point. Hope this helps.

This may mean engine wear or bad oil pump. I would have the oil pressure tested to see if its a shot some where or if the pressure is really low, this is done by removing the sensor and installing a gauge and driving the car to see if the pressure is low, if the pressure is low then more checking is neede to see why,you may have worn engine bearings or bad oil pump. depending on the mileage it may be smarter to replace the engine, not knowing what internal damage has been done already. good day.

Okay What it means is that the oil in your car is either low in level or the oil pressure at low revolutions is low. I highly recommend you to stop driving the car when this happen because you can internally damage the engine with a low oil or a low pressure of oil. Check the oil level first..make sure level is fine and oil looks good. Black and burned oil will give you a low oil pressure as well. If it happen that your car need a oil change. Make sure you get it done and see if the problem goes away. Very rarely oils pressure sensor goes bad but if oil is new and level is fine you can take the oil pressure sensor and connect a tester for a oil pressure. If this is not under the manufacturer specifications.. oil pump is worn out and you have to replace it for a new one.
Good luck and don't forget to rte me. Thanks

It means you have low engine oil pressure due to a failed oil pressure pump or pressure regulator which IS going to lead to engine failure very soon or you have a faulty sending unit or gauge. Do not drive it, get it towed to the dealer! Not meaning any dis respect to your self, but have you checked the oil on your dip stick? Low engine oil level will also cause this...if it's very low or not on the dip stick again do not drive it but go get oil with a friend and top it up and start your car...if the low oil pressure light goes away you got lucky, but there is the possibility you have already harmed the engine depending on how long the light has been on and you may want to see your dealer...we're not talking about a hyundai here, your engine is probably more valuable! haha

The yellow symbol with a line under it means only to warn you if the engine oil level is low when its running. If its RED sign then this is your low engine oil pressure warning light.

this is a light that indicates low oil pressure or low level, 1st check the oil level in the engine when it is hot, if that is ok you will need to have the oil oil pressure tested with a specail mechanical test gauge, don't wait on this, low engine oil pressure or level can quickly lead to engine failure, have a shop check this ASAP if level is ok and light still comes on.

Hi,
That means LOW PRESSURE , not low in volume. Pressure is measured in PSI. The reason that your light comes on when you are at a stop is because your engine goes to idle at a stop and would normally have lower pressure. That doesn't mean you should get a low pressure light though.. I would have it checked by a pro right away as this could be your first warning before a serious problem.
