P1524 Questions

[Bryoung11]

Truck threw a P1524 code and I've already swapped a new oil pressure switch and the check engine light came on again. What else could it be? Thanks in advance.

Have you verified that you are getting good pressure? I believe there is an O-ring that can harden and allow for weak pick up.
