The crankshaft position sensor (CKP sensor) on a 2001 Oldsmobile Aurora is located on the
passenger side of the engine block, near the front of the engine, and typically points towards the crankshaft pulley. It's often a fairly accessible location, but you'll need to be comfortable working around the engine bay to find and access it.
To be absolutely certain, it's best to consult a repair manual specific to your 2001 Oldsmobile Aurora's engine (likely a Northstar V8). A diagram showing the sensor's precise location will eliminate any guesswork. You can often find these manuals online or at auto parts stores.
