That response measn either you are low on oil, it needs changing, the sending unit is bad or a worn oil pump.

The last you don't want to hear, an engine with some bad beariing causing a loss of oil pressure.

How many miles on the engine??

There is about 110,000 miles give or take a few. I thought it might need a oil change. what kind of bearings are they.

Connecting rod and cam bearing you will hear first. TRY the oil change with Castrol High mileage 10W30 (green bottle) and a Honda orig filter.
