Where is position of crankshaft sensor on Chevy Lumina apv 3.8?

The crankshaft position sensor (CKP sensor) on a Chevy Lumina APV with the 3.8L engine is located on the passenger side of the engine block, near the bottom of the engine, and behind the oil pan. Access usually requires removing some undercarriage components to get a clear view and reach it. It's a relatively difficult location to reach.
