My oil pressure gauge in my 2003 Land Cruiser has began to read no oil pressure or very little at all, but I have checked multiple times and my car is full of oil. How do I fix this?

Start with replacing the oil pressure sending unit.

Matches the part number I posted so yes.

Sharing just in case...
@JunkCrzr89 Thanks for the reminder. Mine always lives at 25%, bottom of “normal driving” range, whether driving or idling. Hasn’t moved in 60k miles. I’ve read a bit on here, and seems typical.
Same here. To the point where i get a little paranoid sometimes. I floor it every once in awhile to see it jump, and it does, so figure it's fine.
mine used to work and it will stay low as most; however, one day it quit moving at all. I replaced the sensor, but nothing changed. Since the car works, I left it like that. I was thinking maybe the sensor wasnt ground properly or maybe my instrument cluster was the problem...

QQ: Want to replace this myself. Can this be replaced without dropping oil? Will coordinate with a change if not.

Yes
I looked under my 1998 Toyota Landcruiser and the oil sending unit was there but didn't have the wire connected to it. It looks missing? This is odd because I can't find the wire to connect to the sending unit. Can anyone post picture where the wire comes from?
I fixed my Low Oil Pressure by replacing the Receiver (the Gauge in Cluster, Part Number 83885-6A840)
My receiver is defective as well. SUV powered off and it was on the low position. Powered on and it's stuck near the high position. I use a GlowShift oil filter adapter and connect an oil pressure unit as well as an oil temperature unit. I bought a Glowshift dual gauge with a digital led number only so now I know how much psi and fahrenheight the oil is. With the 100 series, the manual says when its idle it should be above 4.3 but I get around 17. When its moving, it should be above 43-85. Google Glowshift if you plan on using an external gauge. I plan on doing another to monitor the coolant temperature as well as the transmission temperature using the 2 in 1 temperature gauge. Hope that makes sense!
