On a 2000 Nissan Maxima V6 (VQ30DE engine), the crankshaft position sensor (CKP sensor) is typically located on the
passenger side of the engine, near the
front of the engine block. It's usually mounted on the
transmission bellhousing, close to where the crankshaft snout meets the flexplate or torque converter.
However, it's crucial to consult a repair manual specific to your 2000 Maxima V6. The exact location can vary slightly depending on specific engine variations and even minor model year differences. A repair manual with diagrams will give you the most accurate and reliable information.
