Ok I'll try that.IF you can get a small screwdriver and place it here - it should come apart. OR are you trying to remove the entire connector from the sensor? Not sure the latter is possible.

Yep. A hair dryer application might be useful.Doing it in a warm environment if possible is best IMHO.
It has been my experience that cold/frozen "plastic" parts are much more prone to "accidental breakage" when prying or squeezing.
