First question I will ask is are you sure you unplugged the oil sensor. The reason I ask is because it is a bear to get to. Located on drivers side about the middle of the engine.
Next, have you checked for the sensor wire to be grounded making the gauge read high. The oil pressure wiring junctions at the panel on the back wall inside the p/s engine door. Use a meter or test light and test for a grounded wire. The wiring should be labeled for the oil sender. I think it is the #1 wiring. See what wires are the same color as the wiring you unplugged.
As far as the guage goes, you should be able to remove it by reaching under the dash and unscrewing the back side of the gauge. Gauge will lift out with wires intact. 10 minute job.
Bottom line is if gauge is grounded, it will peg out. If wiring to sender is not gounded, you need a gauge.
