Oil Pressure Light and Beep Alarm after 5 or 10 MPH

On the Brakes, take each wheel off in turn, and check each wheel HUB in turn to ensure there is no break or chafe on the exposed cable, or that a plug in has not disconnected.
At the same time check that each HUB exciter ring for ABS sensor is clean and not broken/missing.
Then check that each ABS sensor which is located on each back mount, is clean and air gap set at approx. minimum of .010 inch [10 thous. of an inch] between the "nose" of the sensor and the exciter ring on the HUB.
I would need to know about the OIL pressure problem.
Is it the LOW OIL pressure lamp that was glowing continuously, or the Pressure Gauge reading that is "acting up"?

Oil pressure problem is probably the screen in the oil pump pick-up it is so fine that it pluggs up VERY BIG PROBLEM WITH THESE CARS.oil change oil change!!!!!! sometimes you have to actually remove the screen in the pick-up which involves pulling the pan
