Where is crank sensor on 03 Chevy 2500 hd truck?

The crankshaft position sensor (CKP sensor) on a 2003 Chevy 2500HD is located on the passenger side of the engine block, near the front of the engine. It's usually mounted close to the crankshaft pulley, but its exact position can vary slightly depending on the specific engine (e.g., 6.0L or 8.1L).

To be certain, you should:

* Consult your vehicle's repair manual: This will have diagrams and precise location information.

* Use an online parts diagram: Many websites, like AutoZone or Advance Auto Parts, allow you to look up your specific vehicle and see diagrams showing the sensor location. Search using your VIN for best accuracy.

Looking at diagrams will help you locate it visually, as its a small sensor. Be careful when attempting to locate and replace it, as it's near moving engine parts.
