I just cleaned my IAT sensor, it was a little dirty, not as much as I thought, but truck has over 260,000 miles, I assume it's was 'bout time.

Well, I just made a 650miles trip and my mileage went up 2.5 miles/gallon.

I couldn't believe it, so on the way back I checked again and sure enough I've used 30.1 gallons in 647 miles which makes it 21.4mpg

I was averaging 18.5/19mpg earlier, this saved me $ 30.00 in fuel on the whole trip....

Here's instructions on how to do it:

Sounds good , but i couldn't get the link to work on the location of the sensor, also what did you use to clean it with . How about the MAP sensor can you clean it as well ?

yes the MAP sensor can be cleaned.

i used carb and choke cleaner.

1" 1/4" DS for map sensor and 13/16" DS for IAT sensor.

Okay, now I have the question. How do you clean it? Is there any other sensors that need maintenance? I am new to diesel this year! Help will be appreciated.

spray carb cleaner is what i use..... i installed a new one and am surprised to see a lot less smoke, i haven't checked mileage yet, but my guage doesn't move as fast..... we'll see
