Where is the crankshaft position sensor on 1994 GMC Sonoma 4.3 vin w?

The crankshaft position sensor (CKP) on a 1994 GMC Sonoma 4.3L (VIN W) is located on the passenger side of the engine, near the front of the engine block. It's usually mounted on the engine block itself, close to the crankshaft pulley. It's a fairly small sensor, often with a single wire connector.

However, precise location can vary slightly depending on specific engine variations. A visual inspection with a repair manual or a detailed diagram of your specific engine is recommended for pinpoint accuracy. Using a repair manual specific to your vehicle's year, make, model, and engine is the most reliable way to find it. You can often find these manuals online or at auto parts stores.
