From the 2 temperature readings it sends data back to the computer and makes adjustments to the fuel flow. It is part of an EPA thing to clean up diesel trucks. I have been doing these at 600,000 a year for 2 years and it is ramping up.
Just a heads up of something else to look for when dealing with a diesel. I can post some pictures of the housings so that a guy with a new Cummings can look to see if he has them in place. I do not know how they respond to HHO, but this may be a thing to look at on a new diesel. Just another thing that has to be over ridden...lol
