Either you have a shorted 5 VDC Supply wire to the sensor or its open.

Check 5VDC on other sensors and see if they have proper 5 VDC. When I get home I will tell you what sensors to check.

Well I replaced my ignition switch today and still have 1635 code. I unplugged my oil sending unit and 1635 code is gone but now have oil sending unit code. Not sure it's the oil sending unit or a bad feed back. Ugh!!!

Replace the oil pressure switch. The op switch and map share that 5v ref. You already diagnosed your problem by unplugging the switch and the code not resetting.
