Low oil pressure or fluctuating oil pressure.
The oil pressure gauge is going to fluctuate on a Toyota Tacoma or any automobile. The oil pressure is less when the auto is idling and more when the auto is going down the road.
symptoms of high engine oil pressure
No oil pressure, engine noise, engine failure.
High discharge pressure and low liquid line pressure
under the bonnet

As the engine speed increase so does the speed of the oil pump. the faster the pump turns the higher the pressure becomes. When changing gear the engine speed drops along with the oil pressure.
I know in my '97 Gmc Jimmy the oil sending unit was bad when I had the same problem holding oil pressure. When I'd start my truck it had almost 40 lbs of pressure that would slowly fall off to nil unless you accelerated. Then the pressure would rise somewhat.
Low oil pressure Low cylinder pressure Anti freeze coming out of the tailpipe (sickly sweet smell) Water in oil Oil in water Frothing or bubbling in radiator
The oil pump turns more at higher revs, this is then producing more oil pressure, so when you change gear the revs are in a lower range so the oil pressure drops.
low oil pressure if you have a guage instead of a light and usually accompanied by valves ticking showing the need for more oil.
You dont want to feel OR hear the symtoms. If you think you have a bad pump unscrew the oil sender and screw in a pressure gauge.
Low oil pressure or failed oil pressure switch.

40 - 80 psi at idle, depending on what the engine is.

Either the oil pressure is low, or the oil pressure sensor is faulty, or the computer is sending the message without reason. Do-it-yourselfer can replace the oil pressure sensor. Look it up on a parts website like Rock Auto (rockauto.com) or Advanced Auto or similar site. Locate it on your vehicle. It will be screwed into the side of the engine with a wire coming out of it. Using a wrench, remove it and replace with a new one. If this does not stop the low oil pressure message, then one of the other two reasons are the culprit and a shadetree mechanic should not tackle either of these. Take it to a professional.
Oil level and oil pressure are different. You don't need to have full oil to get normal pressure.
sounds like shes ready for a good freshin up low oil pressure sounds like worn oil pump and excessive bottom end bearing clearence,recommendations rebiuld it.
I'm not a mechanic / technician but I've heard of a plugged PCV system ( valve, hoses etc ) blowing the oil dipstick up off its seat - but I don't know if that raises the oil pressure reading on the gauge ? ( of course , there is a normal change in oil pressure from idle as the RPM's go up - to a point )
the pressure of oil that the oil pump is pulling?
If it is an oil pressure switch it grounds out internally at a set pressure to send a?æsignal to the oil pressure light that the oil pressure is low. An oil pressure sending unit sends a ?ævariable voltage signal to the gauge indicating the pressure.
