New Holland t4.75
First time poster here. I recently inherited this tractor from my uncle and have been using it recently to tend to his cows. Last week the low oil pressure light came on and I immediately cut the tractor off. I’m kind of lost trying to fix it. Firstly I will be changing oil and filter this weekend as I’m unsure of previous maintenance done. If this doesn’t fix it I’ve been reading on here and other places to screw a gauge into the block to check pressure but don’t know where I would screw it into. Does anyone know where the pressure sensor should be? Any insight or help would be greatly appreciated!

Put an analog gage on it. Sensors aka: idiot lights are just that, idiots.

So today I changed the oil and filter and jumped on it to see the following code. Any idea what this means?
