also with my last lumina i have i guess it was crank shaft sensor but in end cost me $900 bucks for it as they did plug wires and module etc

but for crank sensor they told me they had to drop oil pan and we all know how long that takes well they say they have to do that cuz usually the sensor magnet breaks off in engine is that true? and if so its a magnet ill will stick to bottom so if i try changing sensor is it gonna be broken off or what not? and whats the best way to replace it
