Low Oil Engine Level Lamp Control Circuit

What is a Low Engine Oil Level Lamp Control Circuit and can I change it myself? I am reasonably handy.

The “circuit” involves the level sensor, the display device, and all the wiring between the two. I assume that you don’t have it diagnosed as to what part of this circuit is actually defective.

From what yu are saying, this sounds out of my range. Is this an expensive repair, and if this is not repaired promptly, will the problem damage the car?
