1997 Dodge diesels come with the 12 valve cummins engine. It is fully mechanical and does not have a camshaft position sensor. "Dodge cummins diesel forum" is a good resource for dodge cummins owners.
In 2004, the Dodge Cummins Diesel was not equipped with an oxygen sensor. The 2007.5 and newer Cummins 6.7 liter Bluetec diesels have an O2 sensor in the downpipe. Typically, only particulate filter equipped diesels have O2 sensors.
Dodge, Ford only had the Cummins in the F-650 chassis. Ford used International diesels until, the new 6.7l V8 which they built in house.
If equipped, it is below the injection pump.

Cummins is good. Dodge is not. Cummins has always been a good engine. Dodge is lucky to have the contract with Cummins. I have 2 Dodge Cummins (an 1992 and 2006). Both have electrical problems and the transmission in my 2006 isn't great and that's with stock power and only 93,000 miles. The 12-valve Cummins is all mechanical- easy and cheap to get power out of it. The 24-valve Cummins is computerized- have to buy a programmer. The best combination would be a Cummins in a Chevy.
Cam sensor on a 2006 Dodge Cummins is found just below the fuel injection pump. It is attached to back of the timing gear housing. It is attached with an Allen head bolt.
Below the injection pump, on the back of the timing cover.
Because Dodge wanted to sell a Diesel version if the truck. Diesels are long lived, more rugged and higher torqued than gas engines. Chrysler doesn't make one of their own. Why invent one when Cummins makes an excellent pickup sized diesel?
It is on the left side of the engine. Follow the fuel lines and you will find it.
Cummins owns the engine. Dodge just offers the computer instead of cummins. Cummins is a private company it is not owned by Ford or Dodge.
The timing is adjusted by the three bolts that holds the injection pump. The holes in the pump are slotted.
