Where is the crankshaft position sensor on a 2000 4 cylinder S10?

On a 2000 4-cylinder S10, the crankshaft position sensor (CKP sensor) is typically located on the passenger side (right side) of the engine block, near the crankshaft pulley. It's usually a relatively small sensor with a single wire connector. However, the *exact* location can vary slightly depending on the specific engine (e.g., 2.2L or other).

To find it definitively:

1. Consult a repair manual: A Haynes or Chilton repair manual specific to your 2000 S10 4-cylinder will show you a diagram and precise location. This is the most reliable method.

2. Use an online parts diagram: Many online auto parts stores (like AutoZone, Advance Auto Parts, etc.) have diagrams you can browse by selecting your vehicle's year, make, model, and engine. Look for diagrams showing the engine's components.

3. Visual inspection: With the engine cool and the car safely parked, carefully inspect the passenger side of the engine block near the crankshaft pulley. Look for a sensor that resembles the CKP sensor descriptions (small sensor, single wire connector). Be cautious around moving parts.

Remember to disconnect the negative battery cable before performing any work near the engine to prevent electrical shock or accidental starting.
