The location of the crankshaft position sensor (CKP sensor) on a 3.1L Chevy engine (typically found in various GM vehicles from the late 80s and early 90s) varies slightly depending on the year and specific application. However, it's generally found on the
passenger side (right side) of the engine block, near the bellhousing.
It's usually located near the crankshaft's pulley, but not directly on it. You'll likely see a single-wire sensor with a connector near this area. You might need to look closely, and a repair manual specific to your vehicle's year and model will be the most reliable guide for precise location.
