    You need serious heat.
    Mapp torch from Home Depot is minimum
    Oxy Acetylene with a jewelers tip is best.

    Heat the area around the sensor till it's cherry red. Spray PB blaster on it while still red, disregard the fire that just started.

    Let it cool for 15 minutes, shooting it with PB Blaster every minute or two.

    6 point socket on a 1/2" ratchet and a 4 foot breaker bar.
    It'll either snap or come out.

    Sometimes it's worth paying the dealer 400$ to fix things.
