Low oil pressure

[baljitsinghit424]

Have code p06dd on yukon xl 2016 5.3. Replaced sensor doesn't help. Have whining noise, low oil pressure at idle 10psi. Rolling 33 psi at 1500 rpm.
Thinking about replacing oil pump. Please mention part number or suggest better oil pump than gm have lower failure rate if someone had that problem.

Thanks.
