Where is the crankshaft sensor located for a 1997 4.3 Chevy?

The crankshaft position sensor (CKP sensor) on a 1997 4.3L Chevy engine is typically located on the passenger side of the engine block, near the bellhousing. It's usually mounted fairly low and might be somewhat difficult to see without removing some components. It's a small sensor with a single wire connector.

However, it's crucial to consult a repair manual specific to your 1997 4.3L Chevy engine. The exact location can vary slightly depending on the specific engine configuration and even the year of production within that model year. A repair manual will have diagrams and precise details to ensure you find the correct sensor.
