Where is cmp and ckp located on 3.9?

Answer 1

On my GMC V6 Sierra, the Crankshaft Position sensor ( CKP) is located on the front crank shaft cover, right side. The Camshaft Position sensor (CMP) is located under the rotor in the distrbutor. I have to replace both I think, but don't know until I take a look at both. I suspect the one under the rotor is loose. Truck runs great one day and like bad the next. Henry

On a Dodge 3.9L the crank sensor (ckp) is behind the passenger side cylinder head in the top of the bell housing. The cam sensor (cmp) is inside the distributor, under the rotor.
