Pressure sensor detected as both empty and full

From Service Manual 105479, p.51:

1.Check the terminals efficiency on the CN1 Connector Card.

2.Measure control board supply voltage at the test points. Expected: 12 VDC and 5 VDC; a drop below 4.75 VDC on the logic rail points to a failed onboard regulator.

3.Inspect all connectors on the main control for corrosion, thermal stress, or backed-out pins. Reseat each connector with the power disconnected.
