Where is the Oil Pressure Sending unit grounded? Is the ground located on the rear of the head?

Sensor is plugged in, but DIC is showing Oil Pressure XXX

It is a discrete circuit, in other words, connected directly to the PCM....all three wires.

If the ground were open, the pressure would read maximum(off scale high). You most likely have a short to voltage. Water getting in the connector will do it, especially for those who have replace the sensor via the "cut a hole" non-method.
