Try buying the Jeep sensors from a dealer. My Neon kills an O'reilly's crank sensor every February, and every August, like clockwork. The aftermarket cheaps out on the winding wire, and they break internally from the magnetic forces.
I only use factory cam sensors, too. On the same Neon, they develop an internal leak and the oil pressure pushes the aftermarket sensor guts out. The factory sensor is designed in such a way that this impossible.
These are both failures that I see over and over on many cars.
I'm getting to the point where I don't buy anything from the aftermarket unless I can find a Carquest somewhere (they're not common around here).
