2004 lincoln avaitor oil light comes on the engine shuts down
Does the oil light come on BEFORE the engine shuts down? I have to ask because it is NORMAL for the oil light to be on when the engine is not running. I had a customer that said the same thing just last week. After we wasted a bunch of time (which the customer ended-up paying for) checking the oil level, the oil pressure, and verifying correct oil pressure gauge, light, and sending unit operation, it turned out that the crankshaft position sensor was bad and causing the engine to shut down and it had absolutely NOTHING to do with the oil light - it was functioning as designed.
If the oil light is coming on before the engine shuts down, the first thing you need to do is check your oil level. If the oil level is OK, you need to check the oil pressure with a gauge to determine if there is an actual engine oil pressure problem or if the oil pressure sending unit, gauge or light is malfunctioning. Also, it is highly advisable to not drive the vehicle AT ALL if the oil pressure light is coming on while driving until the cause of the light coming on has been determined and repairs have been made. Otherwise, SEVERE ENGINE DAMAGE may result.
