Default Changing knock sensor and bolt broke in half...

What should be a routine fix just went really bad. It's already hard to get in that area and the bolt snapped in half while trying to unscrew it, leaving half of the bolt still screwed in. With no way to drive the car without being able to secure the sensor what can I do to get the rest of the bolt out and also what size bolt do I need to replace it.

Are there exposed threads to grab onto? You can always try a bolt extractor.

Gotta pull the intake manifold off to get it. Not the end of the world. Trust me when I say it will be easier in the long run than trying to kludge it out with everything intact.

x2 take the intake off

if you can get a stud remover on there it's worth a try. Best bet is take the intake off for sure. Remember aluminum reacts differently, meaning I wouldn't use heat. A blunt punch and a firm rap with a hammer should loosen the threads up enough to get it out.
