Oil pressure gauge

[cj5]

Hi all I have a 2007 suburban Ltz it's got 155k on it and the oil pressure gauge just wiggled out it says 0 psi so I shut it off then checked oil and full then started it again and it said 80 and then 0 and has stayed at 0 since then I drove it home and around a little and it still says 0 I'm guessing the sending unit may have gone bad? How hard to change

Hi I just had that happen yesterday an fixed today. Do you have a scan tool? My issue was the oil pressure sensor. If that's the issue it's not hard to do. Just need patience bc its hard to reach

Is the scan tool the one oreillys has just says the numbers?

 

[chris08]

Yea what was the code the scan got?

I haven't done it I was asking if that was the right tool I'll get it scanned in the morning I hope I just have the same problem as you new cars always scare me when they need to be worked on Iv only really worked on old vehicles

My sending unit went out. That was the symptoms. I don't think it never put up a code. Took about 30 minutes simple just hard to get to.
