Hi, my name is ***** ***** you for asking for me, I will try and help you out.

When you run engine or when this happened any louder engine noise?

If no unusual noise than you need to replace oil pressure sensor (OPS) that is the most common problem or corrosion on plug.

OPS should be located either in engine block by oil filters or on manifold oil filter connects to.

To find out which one disconnect the sensor and turn key on, start engine and make sure oil pressure reads 0 or engine light is on.
