Searched the posts but didn't find the answer...

Looking for a diagram or picture showing the location(s) of the O2 sensors on my 06 Ram 2500 (Laramie; 4x4).

I'm not having issues...just looking to do some PM (200K on the truck, so figure they're probably getting close to needing changed).

Also any secret tips to help the change-out go smoother.

 

I don't think any diesel had O2 sensors until 2007.5 model year, when the phased in the particulate filter.

 

Correct... The 2003-2007 5.9L Common rail engine have a very basic ECM that runs virtually open loop.

There are no sensors in the exhaust system.

 

StealthDiesel has it right. Shouldn't be anything to worry about!

 

wow.... now I feel like a dufus... Thanks for the education!
Hmmm...so I wonder what am I going to PM now
