Spray it with PB Blaster or Aero Kroyl. (WD-40 is not a penetrating oil and is all but useless for loosening stuck bolts IMHO.) Slip the wires through a six-point box-end side of a combo wrench and get that on the sensor body. Get a looooong combo or box-end wrench and hook the box end onto the open end of the first wrench. Push with one hand, use the other to tap the first wrench with a heavy hammer. The sensor will let go...
