Jellybean Posted November 30, 2012 Share Posted November 30, 2012 •The oil sender does not have an "OUTPUT" . its a variable ground •In an Auto setup (More pressure= less resistance, makes the gauge go up), •More pressure= less resistance •Less pressure= more resistance What I can do: •Remove the wire from the sending unit. The gauge reads full scale. •Short the wire to ground and it reads "0". Question With the Gauge and Sender off the car , How do you trick an oil pressure sender into measuring pressure?, so I can get the variable OMH reading on the Multimeter or is the only way by putting it on the car with the Engine running?
