Oil pressure warning, but got pressure?

[SweSupra]

Hello!

Iv got this problem, it doesn't feel good driving with it.

So after a minute or so after starting the engine cold, the oil lamp shows up
and stays on untill i kill the engine.

However the oil pressure is good, if i can trust the original pressure gauge?

Shouldn't those two work together or is it two separate systems?

And there is one thing too! Im not 100% sure that i got the right oil stick, i fear its to short, cuz there is on that is shorter right?
Im sure i filled the right amount of oil at last change and it just showed up on the bottom of the stick

You need to specify which engine you have. The measurements for 7M-GE, 7M-GTE, 1G-GTE and 1JZ-GTE are all going to differ, I'm sure. If it is a 7M, those measurements have been posted and you should be able to find them is you search the forum a little. If it's a 1JZ or 1G there are very few owners of such vehicles here... If you can find out who they are you may want to try sending them a PM directly.
