You should check and make sure that you oil level is full. Or make sure that its not past time for an oil change bcause if its past or time the oil is all broken down and thin and the oil pump gage says theres no pressure
Replace your oil pressure sender and see if the dash warning lights turn off. If after changing the oil pressure sender you still have oil pressure warning lights on, you may have to replace your oil pump in your oil pan.
Its hard to say for sure but chevy uses the oil pressure sending unit as a back up power system for the fuel pump so if the fuel pump relay blows out power will go to the pump through to oil pressure unit so even though the gage is working it could be a problem inside the oil pressure uint for this secondery back up fuel pump system. Dose the gage stay at 45 PSI when the light is on or drop down when the ignition is turned off if it holds pressure i would look at the pressure sending unit its probably not giveing a correct reading not to say you have an problem with your oil pressure its to new for that but you need to be able to trust the reading
It sounds like it could be a problem with the ecu but it would be best to take it to a mechanic to get any error codes off the computer. The service light on most vehicles just trigger after a certain distance it doesn't mean there is no faults. It's likely a sensor or a problem with the ecu. You can only tell after the ecu has any error codes read off it.
Check gauge light can come on for a number of different things, from Low fuel to low oil pressure to high engine temperatures. When the light comes on check all the gauge's and see whats causing it, one or more of the gauge's will be showing an issue, Low fuel or low oil pressure, Low battery power. Any of the mentioned things can cause it... Figure out whats causing it then you can remedy the situation...
This isn't a definite fix, but it may be that the gasoline in your tank is 'sloshing' forwards and backwards and your sensour is getting readings when the gasoline is in different positions in your tank. The connection is actually above your gasoline tank and you'll have to take off the tank harnesses and drop the tank if you want to check to see if the connection became slightly loose, otherwise you can just fill your gas tank and reset your temporary milage gage (that's the little black button near your RPM meter) and remember how many miles you get per tank.
