They work with the same  principles. They’re not different sensors. They work with the same  principle.   So here is the module that interprets the signals from the sensor itself. So here, we’re looking at the functionality of it, and this right here would be the the exhauststream coming through where we have NOx emissions and some oxygen left. We might have a little bit of other CO2. We’ll have nitrogen, but we have oxygen and NOx emissions.   And the goal here is to work very much like a wideband sensor with a few pumping cells. So way this works is this diffusion chamber right here, the first pumping chamber allows NOx emissions and oxygen to penetrate the barrier. And when it comes in here, it does a measurement very similar to a wideband sensor to see how many oxygen molecules are here compared to the reference that we would be working against.   If we have more oxygen molecules than we want for our target, the pumping current would turn on and we would pump the oxygen molecules out, which would then only leave us with the NOx molecules. So the whole idea here, get rid of all the free floating oxygen molecules, get those stripped away, which should leave us with only the NOx, molecules that will go through the second diffusion barrier.   So in this diffusion barrier, it comes through then here is what I like to call little mini catalyst because it really is, in essence, like a little mini catalytic converter because as soon as the NOx, molecules hit it, it splits it apart. […]

We’ve been through the low-pressure side and the components on the high-pressure side. We’ve talked about the injectors themselves and all the related components around them. Now, the magical question […]

So this replaces this filter that we looked at in the early style. Not a problem, okay? So, you have to take the unit out, pull the bolts apart, basically, and then you’re gonna go ahead, and put this in, okay? So you put the new filter in there, it’s got a strainer screen here, it’s got basically a filter here. This filter’s designed to catch things like the DEF fluid and such that someone may have accidentally put in a tank which we know is a big problem. So, this is where you’ll see, actually, a little bits of DEF crystallizing in this particular area. So this filter takes a little longer to put in than the other one, but it’s more bulletproof, and it’s a far better filter. Ford has really upgraded the filter. Now remember, the fuel pump is not in this assembly any longer. The newer trucks with this type of fuel-filter housing, the fuel pump is actually in the tank. So, bit of a difference, okay? Now, there’s also an O-ring seal of course, that you must make sure you put in there. This O-ring seal has to go in there to seal this housing correctly. Make sure you do a good job putting the seal in there. Put a little bit of fuel on it to lubricate it, pop it into place, put it together, and you’ll be in good shape.
