Oil Pressure Low Shut Off Engine

I have a 2011 1.4 Turbo and last night I got "Oil Pressure Low Stop Engine" on the dash. Car seemed fine. No rough idle, no codes. Nothing.
Watched a few YouTube videos over night and this morning I added Motor Flush thinking that would maybe help clean things out , drained the old oil and proceeded to do an oil change. New filter and all. The message went away. So I thought. I've driven the car a few times today, a few miles here and there, and as I'm driving the message comes and goes.
Its very random. The message come on for a few seconds and then go away for a few minutes then come back on and vice-versa. It's random.
I've read it could possibly be the oil pressure sensor but idk. Like I mentioned I'm not getting any codes. At least not related to that.
Not sure if a bad oil pressure senor would prompt a code or not.
also, i am noticing that the fan is turning on now as soon as I start the vehicle. It never did that before. and it seems to be blowing at a much higher speed also.

My check engine light is on but the one code that is showing is for something else. (Brake pedal sensor)

Has anyone experienced this before? And if so did yall resolve the issue

Thanks in advance.

The last thing you want to do is a "Motor Flush" if you actually do have low oil pressure. In my opinion, most engine additives are like putting a band aid over a bullet wound. A worn out engine is a worn out engine. No quick fixes for that.

Have you physically checked the oil pressure? That will tell you what the issue is. Low oil pressure or a bad oil pressure switch.

I haven't checked the oil pressure yet but I'll be doing that tomorrow.

I did just replace the oil pressure sensor and the message is still popping up.

ACDelco. That's all they had. Surprisingly.

I spoke to a mechanic today. I mentioned to him what my car was doing and he said that the filter that goes inside the motor is likely clogged. He's dealt with this situation before. That's why the message comes and goes when I drive the car.
He said he needs to take the heads off to get to it. I believe hes talking about the Engine Valve Lifter Oil Filter. (I Think) he's quoting me $600 to do everything. Including the heads getting shaven down and reinstalled.

First step is to see what the oil pressure is doing. It might be a faulty oil sensor.

I can't imagine the pump screen getting clogged unless you haven't changed your oil for so long it's turning in to tar.

The oil filter is a much finer screen.

The problem is that I just bought this car a few months ago. Seemed fine when I got it but who knows how well the previous owners maintained it.

The guy I bought it from did mention he was driving to San Antonio frequently which is about 600 miles going and coming. So I'd imagine he was keeping up with oil changes but you never really know.

Oil pressure at idle and at 3500 rmp.

I'm not sure what it's supposed to be at.
