The Camshaft Position (CMP) Sensor detects the position of the camshaft in order to identifiy when piston No. 1 is on its compression stroke. The CMP sensor is used for ignition timing in the Ford DIS igntion system, but not in the EDIS igntion system. Both DIS/EDIS use the CMP signal for synchronizing the firing of sequential fuel injectors.
On the 3.0L vulcan engine, the CMP signal is generated by a single Hall-Effect magnetic switch, activated by a single "vane" spinning around by virture of a synchronized shaft which is driven by the camshaft.
The CMP sensor & synchronizer/shaft are located behind the intake manifold (i.e., back near the firewall on a Ranger) on the top of the cylinder block. If you just need to replace the sensor, it is a simple job of unplugging the electrical connector and removing the screws holding the sensor in place. Here is a sketch of the sensor to give you an idea what to look for:

It is located under the water pump. Make sure when you remove the sensor that you rotate the crank shaft and look in the hole to make sure the pick up magnet is still in there. Sometimes they come loose and cause a no start or long crank. You will need to have the code cleared still.

Testimonial: "Thank you soooo much you hit the nail on the head without asking a million questions that don't pertain to what I need to know. You know your stuff!!!"
when your engine went into that 5 second sputter,
your computer or "PCM" did not get a constant signal from the crank or cam sensors that the engine was running.
These two sensors tell the computer what RPM the engine is turning so it can adjust fuel and spark.
