if so then heat can sometimes do the trick

PB Blaster always works great also

And yes, PB or and sort of Penetration Liquid is very bad for this particular sensor. The only way to no kill it would be to try and make sure the liquid doesnt go part the threads, meaning get it on the threads but not the sensor portion.

When you put the sensor back in, put a LITTLE dab of anti-seize and it will solve this issue.

Dont use a torch, nine times out of ten you will kill the sensor.
