The camshaft position sensor is located inside the distributor.
It used to be called a hall effects switch and controlled spark timing.
Now the crankshaft position sensor controls the spark timing and the hall effects switch controls injector timing.
I would recommend that you buy a complete distributor, you can get them via ebay for under $100.00 and they will come with a new camshaft sensor, distributor cap and rotor.
You will have to have it scanned and have the " cam retard" (distributor timing) adjusted to ensure it is still at " 0" after installing the unit
The truck will start and run fine but it is very important to have the cam retard within 2 degrees either way.
