2014 Silverado P06DD but oil pressure good

[Tim Snyder]

Hi all. I have a 2014 Z71 with the 5.3 and 184k miles. 
 

a few months ago I had a check engine light with a P06DD code. Checked the oil, found it low, topped it off and no further issues. Well yesterday I had the CEL come back on, same code. Checked oil today, on the low side so put some in. Cleared the code and went about my day. Well this evening the code returned even after the top

off. 
 

Not having any oil pressure issues according to the gauge. Idle is at 35-40 psi. 50 psi at cruising speeds. 60psi under heavy acceleration. No strange noises from engine. Running smoothly. 
 

I’ll end up getting it looked at most likely as oil pressure is nothing to mess around with but wanted to see if anyone had any thoughts on it. 
 

thanks in advance

Sounds like your oil pump is failing.

 

Your idle pressure should be about half of what you are saying, they are a two stage pump, more pressure when needed, less when not.

I’ve got a similar issue but on my son’s 2014 VW Jetta. I just put a new oil pump in but have other work I still need to do.
