The crank sensor on a 3.1L Buick V6 engine (commonly found in Corsicas) is located on the
passenger side of the engine block,
near the front (closest to the timing cover). It's usually mounted on the block itself, not directly on the crankshaft. However, the exact location can vary slightly depending on the year and specific engine variant.
To be certain, you should consult a repair manual specific to your vehicle's year and model. A picture diagram in the repair manual will show the precise location.
