Are you looking at the reading through a scanner?
Did you say 56.8 mili volts?
also I forgot to tell you this truck has a K&N filter system on it. The nipple is so long where the sensor goes in that it is not going to be in the air flow which may be a problem as far as working properly but since the code sets again after a few seconds without even starting the engine there must ba a circuit problem too.

Well, it should not matter what you use. But either way the readings should match.
Let me know what you get!
Sorry for the confusion. I just want to be sure that we are on the same page.
What color wire are you on?
Ok. yes... that is the signal wire. This is normal.
Now, with it plugged in, look at your scanner intake air temp sensor voltage with the key on and tell me what the voltage reading is.
Well, can you try another scanner?
What you could do is go to the computer and check input voltage on that wire to be sure its the same reading as the sensor output voltage. Maybe you have got a break in that wire from the temp sensor back to the computer?
