Where is the crankshaft sensor on 98 Chevy silverado?

The crankshaft position sensor (CKP sensor) on a 1998 Chevy Silverado is located on the passenger side of the engine block, near the front of the engine, and typically points towards the crankshaft pulley. However, the exact location can vary slightly depending on the engine (e.g., 4.3L, 5.7L, etc.).

To find it precisely:

1. Consult your vehicle's repair manual: This is the best resource as it will show you a diagram with the exact location for your specific engine.

2. Look near the crankshaft pulley: This is your best visual clue. The sensor will be relatively close to it, usually mounted to the engine block. It's a small sensor with a single wire harness connected to it.

3. Use an online parts diagram: Many online auto parts stores (like AutoZone, Advance Auto Parts, etc.) allow you to select your vehicle's year, make, and model, and then view diagrams showing the location of parts.

Caution: Before attempting any work on your vehicle, disconnect the negative battery terminal to prevent accidental electrical shorts.
