Is it normail for Toyota tundra oil pressure gauge to move up and down?

I seriously doubt it! The number one reason cars do that is because the oil level is low and the pump is sucking air, not oil from the pan. Every time it sucks air the needle drops, and when it goes back up it means it's sucking oil again. So check your oil level first...
Also some cars have problems where the tube that goes between the oil pump and bottom of the pan can become either clogged or fall off. If they fall off then the engine will suck air because it isn't in oil at all, or it's only a little bit into the oil. If the tube is clogged then the it sucks a vacuum which is basically the same thing as far as the engine is concerned. I lost a Lexus SUV to a clogged pickup, and it was a known problem with that engine but Lexus knew that they usually clogged after the warranty was up so they didn't tell anyone. A-holes. Last Lexus for me, hope it was worth it guys.
Since Lexus and Toyota share many parts and engines, you may have the exact same engine I did, so look into that!

Oil pressure fluctuates on a Toyota Tacoma?
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.

Based on ambient temperatureBuy a kit with a gauge and instructions
How do you know your oil pump is working on your 1984 Toyota pick-up?
Check oil pressure with a manual gauge
What is the difference between normal pressure gauge and differential pressure gauge?
A pressure gauge indicates actual pressure and a differential pressure gauge indicates the difference in pressure.
Why pressure gauge is called a gauge not a meter?
Because Pressure gauge measures the the differenceof pressure so it is called pressure gauge not meter.
Definition of a compound gauge?
A compound gauge is a pressure gauge that displays both negative and positive gauge pressure measurements. Gauge pressure is a measurement of pressure relative to ambient pressure. For example, if ambient pressure was 14.7 PSI and you were to measure absolute vaccum using a compound gauge, the gauge would indicate -14.7 PSI.
Toyota Sequoia Oil level dropped and pressure went to zero Filled oil pressure still reads zero No indications of engine damage How can I determine if there is pressure and car safe to drive to shop?
Remove oil sending unit and replace with a manual gauge to determine actual oil pressure I also have a Sequoia 2002, Toyota dealer fixed mine because this a Toyota recall. Take your SUV to a Toyota dealer near you.
Why does your rpm gauge jump on your tundra?
Clutch could be skipping
Can bourdon's tube pressure gauge be used to measure negative pressure?
Bourdon's tube pressure gauge cannot be used to measure negative pressure. This is because absolute pressure must be measured and the Bourdon gauge only indicates the gauge pressure.
What gauge measures both vacuum and pressure?
Gauge pressure usually refers to the pressure difference between ambient, atmospheric pressure and the pressure in a vessel or line. A gauge pressure of zero would mean that the vessel or line was at atmospheric pressure. Normally the pressures of interest are ABOVE atmospheric so the gauge pressure is positive. Vacuum gauge pressure measures how far BELOW atmospheric pressure a vessel or line is. As such vacuum gauge pressure may be measured as a negative number - or for convenience it may be reported as a positive number with the caveat that it is "vacuum gauge pressure", meaning that the reported pressure is how far atmospheric pressure is above the pressure in the vessel or line.
What is micro manometer pressure?
A manometer is a pressure gauge. A micro manometer is either a really small pressure gauge, or a pressure gauge used to measure really small pressure difference.
What is the principle of pressure gauge?
pressure gauge works on hooks law principle ,when we applying pressure in end connection of the pressure gauge ,the same pressure operating at end of the bourdon tube.
