Oil Light flashing/buzzer

Hey folks, I have a situation with my 2001 Fleetwood Expedition. My check engine light came on and my oil light is flashing and a buzzer is going off as it flashes. It seems like it is giving out a code of some sort but I searched and searched for information with no luck. After a sequence of flash/buzz, My oil pressure gauge will peg out then return to about the 3/4 position. Anybody had any experience with something like this? TIA

Oil pressure is nothing to mess with, it's like blood pressure. To much not good, too little, really bad! However, the oil systems are alot more stable than the sending units used to monitor them, and in your case I'd:
1. Shut the motor off now!
2. Replace the sending unit (like $30 and a half hour labor and a six-pack) and start the motor and see if the symptoms go away.

Oh, obviously look around for massive oil leaks, but it sounds to me like your sending unit has gone stoopid.

Yup, symptoms of a bad sensor or loose wire. Check the connections and if good, change the sender.

Install a mechanical oil pressure gauge on the motor just to be sure you know what you really have. Not something to mess with! Good luck
