Where is located the crankshaft sensor on Chevy Express?

The location of the crankshaft position sensor (CKP sensor) on a Chevy Express van varies slightly depending on the year and engine. It's generally found near the crankshaft pulley, but can be accessed from either the top or bottom of the engine.

To find it with certainty, you'll need to:

1. Identify your engine: Knowing the engine size (e.g., 4.8L, 5.3L, 6.0L) and year of your Chevy Express is crucial.

2. Consult a repair manual: A repair manual specific to your year and engine will have diagrams and precise instructions showing the sensor's location and how to access it. This is the most reliable method. You can find these online or at auto parts stores.

3. Use an online parts diagram: Many auto parts websites (like AutoZone, Advance Auto Parts, etc.) allow you to enter your vehicle's information and view diagrams showing the location of parts, including the CKP sensor.

Without the specific year and engine, giving a precise location is impossible. However, it's almost always near the crankshaft pulley, typically on the passenger side (right side) of the engine in the front. Sometimes it's easier to access from underneath the vehicle. Always remember to disconnect the negative battery terminal before working on any engine sensors.
