Where is the crankshaft sensor located on a 2002 Cadillac Seville STS?

The crankshaft position sensor (CKP sensor) on a 2002 Cadillac Seville STS is located on the passenger side of the engine block, near the bottom of the engine, towards the front. It's usually fairly close to the crankshaft pulley itself.

However, the exact location can vary slightly depending on the specific engine (Northstar 4.6L or 4.9L). A repair manual specific to your vehicle's VIN or engine code is the best source for precise location and details. A visual inspection, aided by a repair manual diagram, is highly recommended.
