Actually, there is not much that can go wrong with a crank sensor, after all it is simply a magnet rod with wires wrapped around it and molded into the plastic.
The most common problem with a CPS is the connector getting corroded.
The reason most here say "Go Bosch or stay home" is that the aftermarket knock-off CPS sensors have thinner connecting pins and the connector doesn't make complete contact.
JMHO, I'm sure many will disagree.
