Where is the CRANKSHAFT position sensor located on a 2001 CHEVROLET 2500HD?

Answer 1

Can't give you specifics but most Crankshaft sensors (CKP) are located at the front of the motor under the timing cover or at the back of the motor where they can sense the rotation of the flywheel. The rear ones are generally located in the tranny bell housing. Some engines were made with no crankshaft sensor. They get there timing info from a sensor in the distributor. A camshaft sensor. Newer vehicles are being made with no distributor; they must have a crank sensor. It is on the engine block, behind the starter.
