I have just purchased a chip box to get better mpg for my 2.8 diesel, it says to connect it to the air flow meter and to the air temp sensor, i have located them but i can not find the o2 sensor on the exhaust system, can anyone please tell me where this is. I will also feed back on if this does increase my mpg also it has a setting that should give between 20 - 30 more bhp.

i am sorry but i have no experience with diesels. however, the O2 sensor is typically plugged into the side of your exhaust pipe near the cat.

an o2 sensor isn't small, follow the exhaust from block(it could be in the manifold) to the mufler. you might not have one. the dodge diesel just started putting o2's in

I wish they offered the diesel version over here. I tell you what, if you bring it over here I'll find your O2 sensor for you.

There are two O2 sensor on CRD.
One before the catalyst and one after, see image.
