Any suggestion to dig out frozen rear wheel speed sensor?

Trying to replace my rear driver-side wheel speed sensor that is essentially frozen. i tried lightly prying under all the surrounding plastic base but it just chipped off leaving nothing to grab but the wire that goes into the base. I've sprayed PB blaster on it and will leave it sit for the night but the sensor is plastic and I don't know if PB blaster will really do anything. You can tell by the picture that I tried pulling on the cable and that just exposed the wires with out any movement of the sensor. You can also see that the retain screw also snapped when I initially tried removing it.

Any suggestions on how to dig this thing out?

The sensor is toast, do whatever to 'grab' the damn thing and yank it out. You might try an 'easy-out' (typically used to remove a cross-threaded or broken bolt), you could tap it into the sensor and then twist counter-clockwise to break this sensor loose from the inset/hole.

Torch

and or

drill a small hold thru it and then use a pick tool to dig it out.

To me the picks are a must have which I admit I waited a good while getting some. A good pick set and make digging stuff out soooo much easier.

Sears is where I bought mine.

I typed /wheel speed sensor f3 in the bestlinks and this came up:
