DT225 Oil warning buzzer and light when accelerating

[dan34685]

I have a 2002 DT225. I'm getting a flashing Oil light and the beeper soudning off whenever the RPM's are getting over 2000 or so. The beeping and warning flashing increase as I increase the throttle. No rev limit warning. I replaced the Oil flow sensor a few months ago when I had a similar problem. Could it have gone bad again or should I try something else?

Either no oil going through sensor or bad sensor.
