What would cause an oil light to flash?
Why might your warning indicator flash? A low oil level is the most likely cause, but you’ve checked that. The next most likely cause could be worn engine bearings, which allow the oil pump’s volume to squirt more out of places it would normally be retained.
Why is the oil light blinking on and off?
I think the problem may be with either the oil pump and any pressure relief valve, or the oil pressure gauge and/or wiring. What I would do is with the engine idling, wiggle the wire plug at the oil pressure switch and see if the light does flicker off and on, so you may need a helper.
Why does the oil pressure light come on when there is no oil in the engine?
Low Engine Oil Level To create an oil pressure in the engine, the engine needs to pressurize oil. If there is no oil to pressurize, it will be impossible for the oil pump to properly do its job. If your oil pressure light comes on and sometimes disappears, especially when you turn the car, a low engine oil level may cause it.
What does it mean when your oil pressure indicator keeps flashing?
If it starts flashing, it indicates that the oil pressure dropped very low for a moment, then recovered. If the indicator stays on with the engine running, it shows that the engine has lost oil pressure and serious engine damage is possible. In either case, you should take immediate action.
What to do when oil pressure light flickers?
Spin on a new oil filter and tighten it hand tight and then about a 1/4 of a turn more. Fill your engine with the recommended oil. Do not worry about any residual fuel left in the oil, as it will burn off when the vehicle gets up to operating temperature. Let the engine run for about 10 minutes on idle.

When does the oil pressure light come on?
This indicator should light when the ignition switch is ON (II), and go out after the engine starts. It should never come on when the engine is running. If it starts flashing, it indicates that the oil pressure dropped very low for a moment, then recovered.

Why does the oil pressure light go off at idle?
Fill your engine with the recommended oil. Do not worry about any residual fuel left in the oil, as it will burn off when the vehicle gets up to operating temperature. Let the engine run for about 10 minutes on idle. Make sure the oil light goes off in this time. Turn off the engine, then restart it and see if the light goes out at idle.
When does the oil pressure warning light come on?
Oil Pressure Warning Light. One of the first signs of trouble with your oil pressure sensor is when the oil pressure warning light comes on. In some vehicles, this is called the “Low Oil Warning Light.” Whenever this light stays on, it means there is either low oil, low oil pressure, or some other kind of oil problem in your engine.
Can a faulty sending unit cause inaccurate oil pressure readings?
When it detects oil pressure in the vehicle, a switch trips and either the light shuts off, or the gauge becomes active. A faulty oil pressure sending unit can result in inaccurate oil pressure readings and warnings. So, it is important to recognize the signs of a sending unit that needs to be replaced.
Why is the oil pressure light on my dashboard?
There are actually two scenarios when the oil pressure light is on your dashboard. One of them is that it is a false alarm and there is a problem with the oil pressure sensor or the wirings to it. The other scenario is that your engine actually has low oil pressure, which is a little bit more serious.
Why does my oil pressure sensor keep going off?
Whenever this light stays on, it means there is either low oil, low oil pressure, or some other kind of oil problem in your engine. Often, it can be traced back to a faulty oil pressure sensor. Replace the sensor and your oil system should return to normal again. The engine control unit monitors the oil pressure sensor.
