Hello,

Are you experiencing any drivability issues? Any noise from the engine?

If the engine drives as usual and has no other issues, this could be due to a faulty oil pressure sensor, loose or corroded wiring or a bad gauge.

Inspect the pressure sensor, make sure the wiring is secured and does not have any corrosion or pulled out pin.

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
