P0523 and 0 psi oil pressure FIX!!

[Burb!!]

I got the P0523 code and 0 psi oil pressure. Some people could also get P0521. After reading up on what it could be, seems this is a fairly common issue with NNBS vehicles. Turns out the Oil Pressure sender or sensor and the little filter beneath it are the culprits. After a bunch of research(and being quoted $400+ by shops around) I decided to tackle it myself....It was a pain in the ass to get to it sorted out, mainly due to the location of the sensor and trying to fish out the filter beneath; all of which are behind the engine right next to the firewall. FYI I didn't unplug or disconnect any hoses and I didn't remove the intake. So just to help anybody out there that's having the same issue I took a couple of pics of what was required. FYI: I had to make a little hook out of a metal clothes hanger to fish out the little filter. The set of picks I bought were useless because of the length.

Edit: clear codes before starting vehicle so the correct oil pressure can be displayed.

Several threads on here about this issue and the screen that people did not know was there but I have not seen these pics before. Thanks for the info and pics.

Hopefully that is it. The good news is if it is indeed what is wrong, you know exactly what to do.

Or why it isn’t a $500 repair.

I got this two days ago and dropped it off yesterday at my mechanic to diagnose the problem.
I think it was the 0 psi that freaked me out. Wish I saw this sooner, may have to call and see where he is and if he hasn't done anything may go get it and do what Burb! did.

That's unreal
I just paid $198, thought that was more than reasonable.
