Usually it means you don't have enough oil in the motor. Check it! If the oil level is good try having the oil changed, it could be the warning light is because of a clogged filter or really cruddy oil.
an oil light is designed to come on when there is NO oil pressure or LITTLE oil pressure. that said, when your oil light is on before you start your engine there is NO oil pressure to turn it off until you start the engine.
On G cars from the 80s, low voltage list the oil pressure light. There have been many improvements since. May still need some.
Oil light senses oil pressure not oil level
Low oil pressure
Low oil pressure, Failed oil pressure sensor.
There are many reasons for the oil light to come on. You could be low on oil or the oil pressure switch could be defective. Oil pressure is not created by the oil pump. The oil pump provides a volumn of oil. The engine bearings create the oil pressure as oil is being squeezed past them.
not sure that it would say the light would indicate too much pressure, but usually the light will come on when there is not enough pressure (too little oil). inversely, the light may come on if there is too much oil.
That light is for low oil pressure, not low level.
No, it would cause the "low oil" light to come on.
The oil pressure is low or the sensor has failed.
Yes, if the oil pressure sending unit is bad the oil light may come on.
why does oil light come on Oil level is low, pressure is low do to plugged filter or worn engine, or sensor is bad.
