    Welcome to the forum.
    I owned a 2000. I'm not sure where your issue is either. Where are you seeing or reading its showing you a zero?

    Here is one way to check the oil sensor, gauge. Ignition to run, unplug oil pressure sender conn from sending unit. Touch conn to engine block ( good ground) gauge should read at low end of scale. When conn is not touching ground (open) gauge should read at high end of scale. If ok sensor bad. If not check wiring between sensor and gauge for open. Repair if you find any problems and if wiring ok bad gauge.

    Please take a picture of what you are talking about and post it so that we know for sure. Sounds like you are talking about your oil pressure gauge. It measures the oil pressure in the motor. It will stay on "0" if the motor is not running, low at idle, and as your RPMs increase the pressure in the motor will increase. That is what the guage is telling you. It does not measure the oil level, but the oil level does have impact on the oil pressure.

    Thank you OFFGRID. That was my point. What are you looking at Gen1218?

    Check wires for the sensor and you might pull the gauge cluster and make sure the gauge is making sufficient contact with the circuit. I don't recall what pins on the cluster connector is for the oil pressure but if you can locate them you can see if signal is getting to the cluster. If you can't figure it out you can get an aftermarket electrical or mechanical gauge.
