Oil pressure light came on, what does this mean?

When you say the "oil light," do you mean the light that says "Change oil" or are you seeing the red light that indicates low oil pressure?

If you're seeing that red light, that likely means you have low oil pressure and should stop driving immediately, until the problem is diagnosed and repaired.

It's also possible to see the oil pressure light on when there's no issue with oil pressure, if the oil pressure sender has failed or there's a connection problem.

If the oil light you're referring to is the "change oil" light, you will need to manually reset it for it to disappear. Here's how (from Chrysler):

1. Turn the ignition switch to the ON/RUN position (do not start the engine).
2. Fully depress the accelerator pedal, slowly, three times within 10 seconds.
3. Turn the ignition switch to the OFF/LOCK position.
NOTE: If the indicator message illuminates when you start the engine, the oil change indicator system did not reset. If necessary, repeat these steps.

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

Do you mean what causes low oil pressure? This is a very reliable engine for the most part. If the oil light is on or gauge is reading low, have the oil pressure sensor inspected for failure. These sensors do go bad.

If your oil light is on, it means that the control module thinks there is no oil pressure. It could be a bad oil pressure sending unit, or it could be that the oil pump is out and that the engine is actually not getting oil. The engine would need to have a mechanical gauge put on to find out if it does have pressure.

the flashing, beeping oil light is oil pressure, not level. low oil pressure means that the oil is all there, but its not flowing properly through the engine. dirty oil, a dirty oil filter, heavier than normal weight oil, a failing oil pump- any of these could be the culprit

Don't run the engine with the oil light on. No oil pressure means no oil circulation, and damage will result. Have a shop check the oil pressure with a gauge that plugs into the oil pressure sensor port. If no pressure, check if you need a new oil pump.

In most cases the flickering light means the oil pressure is dropping below 5psi. The actual problem could be a faulty pressure switch, or the engine could really have low oil pressure. And that would mean lower engine damage with the bearings or other parts.

well oil lights can generally mean 2 things sometimes they are level monitors meaning when the oil is low it comes on which is the most common and on some vehicles it is pressure activated. meaning it monitors the engines oil pressure. so if the engine becomes old and worn and the main bearings on the crankshaft start to wear the oil pressure will decrease causing the old blown up engine, however generally it is not uncommon for the oil level sensors to become corroded and go bad causing a false light, meaning everything is fine but the light is on, and on the other case if it is a pressure issue you should be able to hear the engine knocking and or sounding fairly rough when it is fully warmed up to operating temp at an idol! good luck

Do you mean the oil level sensor was replaced, or do you mean the oil pressure sending unit was replaced?
If it was the oil pressure sensor was replaced, then I would look into an oil pump going bad, not supplying enough pressure to the oil pressure sensor. This can be tested by putting an oil pressure gauge into where the oil pressure sensor normally goes, bypassing the circuitry that leads to the dash light for the oil pressure.

If it was the oil level sensor, then check for bad wiring.

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.
