Oil gage fluctuations

Sitting at idle, my 2022 tundra sits at about a quarter on the oil pressure gage. But as I accelerate and decelerate, that gage will also go up and down... is that normal? Every other vehicle I've ever owned has maintained a pretty constant oil pressure. There are a few other electrical things that I haven't been happy with, so is this just an update that needs to happen as everything runs on electronics?

 

Probably normal. 2nd gens do the same thing.

 

Its completely normal. As your RPM’s increase so does the amount of oil the pump is moving. At higher rpm its trying to pump more oil through the same size passages and therefore the pressure increases.

The other vehicles you had probably had dummy gauges. They were just there to let you know things were ok but not to inform you of the real time oil pressure. My F150 gauge never moves. But my 1995 4Runner gauge always moves as its an actual oil pressure sensor.

 

Yeah my 2014 did the same thing, quite normal. What I don’t remember being normal is my battery charge gauge moving so much, it’s all over the place on the 3rd gen.

 

Power steering is also now tied to the electrical system now rather than mechanical pump pressure so this, along with presumptively more electrical draw possibilities with all the new tech, could all be directly related to the battery gauge fluctuation. I’m ok with it dancing all day long as long as it continues to provide adequate power and start every time

 

They may also be adjusting the charge voltage. My F150 tune has, no lie, like 6 tables for battery voltage for all sorts of different driving conditions. Each table varies voltage based on battery temperature.

 

Oil pressure is normal at 1/4 at idle. It’s how Toyota has always designed their oil pressure gauges. It seems only 2nd gen sits at the half point at idle. If you’re worried about oil pasture, there is a message when oil pressure is too low similar to this


Fluctuating battery voltage is also normal. The ECM turns the alternator on and off based on battery state of charge to increase efficiency. When the gauge is the middle it’s charging. The ECM commands battery charging during coasting and braking which is why you might notice it more frequently. If battery voltage gets too low or there’s a charging issue, there will be a message for that.


These pics are from Tacomas but it’s the same for Tundras.

 

Well this is definitely comforting. With this being my first Tundra and first super techy vehicle it was weird watching the gauge flux so much.

 

Lol that is so ridiculous. It’s just a different spec. The 1st gen Tundra also sat at 1/4 at idle. I’m sure there’s an oil pressure spec the dealer could check in 10 minutes.
