The cam and crank shaft timing sensors, they are identical, same part number, I would replace both if you decide to replace the cam sensor.

The cam shaft sensor is located on the driver side of the head, just beside the Jake harness where it inserts at the head. This will be at the center of the head.

The crank shaft timing sensor is located on the driver side, lower front structure. There will be a wire loom, holds two little wires, circumference of your pinky finger, it drops down below where the oil fill neck is located and plugs into the sensor.

Both sensors are held in place with a 10mm bolt. You need to remove the bolt and wiggle the sensors out. The crank shaft sensor can be a bear, but it will come out. When you install the new ones, lubricate the o-ring with oil or Vaseline and install. I think the bolts are supposed to be torqued to 15 ftlb if my memory serves me right. I used anti-seize on the bolts before installing and torquing down.

Here is a link to the sensor {link removed. non-oem enigne sensor}.

That is what it looks like, BUT! Only purchase Genuine Cummins OEM sensors! The one I linked to above is a Chinese knock off! Only use Cummins Genuine Parts! Especially sensors! Any truck dealer will normally stock these, or Cummins shop. Make sure the box is Genuine Cummins! Do not try to save a buck on these vital parts.

On edit: Your cam shaft timing sensor, I have the 871 dual cam, you more than likely you have the CM-2250 single cam. If that is what you have, that sensor for the cam shaft is more than likely on the passenger side where your single cam resides.
