Yep when that fails you can't start because the car will have no idea when to fire the spark or I suppose fuel.
Definitely measure and gap/shim. They are stupidly sensitive. They can detect how much the rotation slows between power strokes with enough detail to know when a cylinder didn't put out the power expected of it so they are extremely sensitive to the bumps on the reluctor. That tech amazes me

My 650cc single-cylinder BMW (Rotax engined) motorcycle has a similar sensor/function - the crank position sensor can detect the differences between a compression stroke and an exhaust stroke and the BMS-C uses this to figure the ignition timing at start-up. Unsurprisingly, it takes a few revolutions to fire when starting!
And of course, INPA can even show the rotational conformity, at least it can on the M57TU diesel.
Amazing tech, all right!!
