SOURCE: P0340 Code Camshaft Position Sensor

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:

Assuming you have a 4.2L engine here is the location.


Hope this helps out,

At the right rear of the engine under the intake manifold and to the left of the oil filter. You will probably need to go under the car to spot it, it's the sensor with a three-wire connector arranged vertically. But you can take it out from above. It's held in with a single bolt with an eight MM head located just above the sensor. Un-clip and remove the electrical connector. Unscrew the bolt with a socket wrench & extension bar. Wiggle and pull the sensor out.
here is a picture.

This V-6 has a very hard to find/hard to reach CKP - it is directly under the Distributor, about 4 inches below, inwards toward the Transaxle "bell". Almost dead-center in the back of the engine.
Your going to have to take the Air Filter and the air manifold that runs to the engine off. After that, take off the horn assembly to gain very, very limited access to wedge an extended ratchet into the bowels of the engine. 
I think the same socket that undid the horn assembly fit the CKP nut. It takes 10 minutes to undo the bolt a couple ratchet clicks at a time, at least 15 to get the thing to wiggle out, probably 15 minutes to unconnect, reconnect, and snap back to the fram the wire harness, and at least another 10 minutes to ratchet the bolt back in click by click.

Now you know why they say shops charge $500 in to do this - I think they must take the entire engine out... Very painstaking job that requires patience and precision... but quite satisfying to finish it yourself. 

Good luck and hope this helps,

If your car is a 4.0L there are no camshaft sensor. Only crankshaft sensor and timing sensor. Dont know your problem but if your car is not running it is very common that the crankshaft sensor is faulty. It is fairly easy replaced and located just above the crankshaft wheel atthe front of the engine. It is mounted with one 8mm boult.
