SOURCE: camshaft position sensor
its fairly easy to do, take 30 minutes the most, so definitely, you can do it yourself. just gettin to it, is the pain, but you can definitely do it yourself

The sensor is black and measures approx 3"x3" square with four 8 mm metric bolts holding it in place on the engine. An 8 mm socket with an extension was used to access the bolts and loosen them. Be careful not to drop them down into no mans land. Bright lighting is a must to see what you are doing.
Once all four bolts were removed, the sensor pulled off the end of the engine with a slight tug. NOTE: It is a good idea to have a cloth or paper towel under this area, as a small amount of engine oil is present between the camshaft and the sensor, and thus leaks out when the sensor is removed.
Once the sensor is removed, it is easier then to pull off the electrical connector from the sensor, than before it's removal. This is accomplished by first pulling out the red locking tab to the unlocked position, a firm tug should do it, but a small blade screwdriver was required to pry it out of it's locked position. Then squeeze and pull the black part of the connector, to disconnect the wiring harness from the sensor. Voila! One camshaft position sensor removed.
To reinstall the new sensor, I check that the faces that will come in contact with each other, when sensor is reinstalled, are clean and free of grime and excess oil. Put a light coating of engine oil on the new sensor seal (green O ring) using your finger and clean engine oil. This will help the seal when the sensor is bolted back together.
Install the electrical connector by pushing the wiring connector into the sensor and locking it into place by squeezing the red locking tab into it's locked position.
Re-install the sensor onto the engine with the four bolts. Thread the bolts in, then tighten them gently with a little extra force, in an x pattern when tightening the bolts. This distributes the force evenly across the sensor. BE CAREFUL TO NOT USE TOO MUCH FORCE, SO THAT YOU DON'T STRIP THE BOLT THREADS. ALUMINUM IS A SOFT METAL.
After installation of the sensor, just install everything you removed and enjoy a night out with the money you saved.

IT SOUNDS LIKE YOU HAVE BROKEN WIRE LEADING TO SPEED SENSOR IN REAR DIFF..CHECK FOR ANY SPOTS IN HARNESS WHERE IT LOOKS OUT OF PLACE OR RUBBING ON SOMETHING..ALSO CHECK FOR SPREAD CONNECTIONS IN PLUG AT SENSOR..CHECK ALL FUSES RELATED TO ABS SYSTEM IN UNDERHOOD FUSE/RELAY CENTER

sounds like a bad ecm aka computer to me.have ecm checked
SOURCE: 2000 dodge grand caravan sport, the check engine
no codes found because your checking the PCM,
your problem is you need codes from the TCM,the computer for the transmission,since you replaced the speed sensor the other two things that affect a speedometer and transmission are the input and output sensors,they both screw in the transmission.
