Not the pulley on the front. This is what the crankshaft possition sensor gets it's reading from. It is a toothed ring that is bolted to the crankshaft inside the engine. The sensor is a Hall effect sensor,(magnet?) and as the toothed ring goes past the sensor, it fluctuates the magnetic field allowing the ECU to know where the crankshaft is in the 360 degrees of rotation. There is a 2 tooth gap to give a larger spacing for timing reference for -0- degree reference. In a nut shell.........

Cool, never really knew the actual name of it, always just called it the Crank Position Sensor Ring, lol.
Anyway, I have to agree, unfortunately you're the first one I've heard of with a problem.
(Edited my post, sometimes I'm just not with it, thinking Crank Sensor, picturing Cam Sensor....don't as me why.... )

The 3 mounting pads and bolts on the crank are still there as seen through the CPS opening, the reluctor however is broken apart.
So, I wonder what 'lil surprises I'll have once I've dismantled the engine..... Still have compression and oil psi..... So...... In to the depths I GO!!

Number 7 in the diagram. Correct.
Referred to as "impulse sending wheel" by MINI. "Reluctor" is another term looks like used by other manufacturers to describe it.
Had not heard of one failing like that.

Set to the right in the picture.
Good luck on install.
