It's probably the sender itself that is bad. Mine's failed twice. The sender is on the oil filter base. You have to take the oil filter off then remove the hose to the oil cooler then remove the base. It's tricky but if you are mechanically clever you can do it yourself.
There's actually 2 senders. The one on the inboard side of the filter base is for the gauge. The other one on the outboard side of the filter base, the one that's easy to get to, is for the light in the gauge that comes on when you have zero oil pressure.
That's a double check. You'll notice when you turn the ignition on there is a light on the oil pressure gauge, when you start the engine the light goes out. Check that light everytime you start the car.
So with your issue I wouldn't worry too much as long as that light is functioning. If the gauge reads zero and that light is on, you'd better shut the car off and have it towed while the repair bill is still less than $2,000.
