The crankshaft position sensor tells the engine computer the engine's position and speed; when it fails, the computer loses that signal and the engine won't run properly or start. These sensors fail with heat and age. Replacing the sensor restores reliable starting.

Can a crankshaft sensor cause a no-start?

Yes — without its signal the engine often won't start or will stall.

Why does my MINI stall when warm?

A failing crankshaft sensor is a common cause of warm-stalling; diagnosis confirms it.
