The oil light comes on when the oil pressure sensor detects low oil pressure. The amount of oil has little to with it, although very low oil levels can cause loss of oil pressure. The best thing to do is to have the engine's oil pressure checked with a mechanical oil pressure gauge to ensure that the oil pressure is sufficient at all operating speed and temperatures. If the oil light is still flashing on and off and there is no indication of low oil pressure by the gauge, then replacement of the oil pressure sensor is recommended.
The oil light is not an indication of oil level; rather it is an indication of oil pressure. If the oil pressure is low enough to light the oil light, you should be hearing some rattling in the engine. Otherwise, it is possible that the oil pressure sending unit is defective. You are lucky if that is the case, because some vehicles are wired that if the oil pressure sensor indicates low pressure, the engine will shut down to protect itself. You should have the oil pressure checked with a mechanical gauge ASAP and take whatever corrective measures are necessary.
Hello....When ever the oil light comes on and stays on..this is an indication of a low oil pressure reading...I would start with checking your oil level in your engine..or have service personnel check it...It could also be caused by viscosity breakdown of the oil...which can result in lowered oil pressure especially if it is way overdue for an oil change...and on very rare intsances...a faulty oil pressure sender or oil pump could be the trouble...But I would start with the oil level....and go down the list...I hope this was helpful.....PEACE!!!!!
If your oil level is good, that is between the low and high marks, that light blinking is an indicator there is a problem with your oil pressure. The light flashing could be low oil level, a bad oil pressure sensor, your oil pump going out or a clogged line or pick up. Start by checking your oil level, then test the sensor if both are good drain your oil and pull the oil pan off to see if the pick up is clogged, if it is clean it. If everything is good at this point then the problem is the pump itself and you'll need to replace the pump.
the oil light is coming on due to sensed low engine oil pressure, this is not a level issue unless u are about 3 quarts low, oil pressure indicators don't leave any computer codes, so who ever told u that is wrong, u need to test the oil pressure with a mechanical gage when the oil light is on, until U need to confirm that u don't have a real pressure issue here or you can burn out the engine bearings, if the pressure checks ok then rplace the oil pressure light sending unit in the engine.
If the oil light is on, Don't drive your car until you've checked the oil level . The oil light is an indicator that warns you when the oil level has dropped to an unsafe level and will not allow proper oil flow thru the motor because the oil pressure is dropping.
Don't take a chance! Check the oil level. Make sure it's between the full and add 1 quart line. If you don't see anything on the dipstick, it's really low... If you run your car with low oil, you're going to freeze up the motor.
If the oil level is ok and the oil light is still on, have the pressure sender checked to make sure there's proper oil pressure. The light will stay on if there's a problem..
Yes....Check oil level. Listen for tapping noises from engine....Change oil, have someone put a pressure gauge on engine (a real mechanical one) If pressure is OK, change oil pressure sending unit. If pressure is low, you have a real problem (internal wear) If so, consider a rebuild or replace vehicle.
