07 Yukon Denali p0011 code

20

Asked by Aug 19, 2019 at 01:12 AM about the 2007 GMC Yukon XL Denali 4WD

Question type: Maintenance & Repair

I have this problem where oil pressure idles at 40
then slowly starts dropping down to i say maybe
20. Then after a while code P0011 comes on.
Replaced sending unit with ac delco, replaced
phaser with ac delco, replaced cam sensor and
actuator, replaced oil pick up o-ring, no longer has
an oil pressure sensor screen, yet oil pressure
drops and i get this code. Any help would be
greatly appreciated. There is power and ground to
cam sensor and actuator as well
