Engine/Transmission (1998.5 - 2002) HOLD ON! Before you try to remove your IAT sensor...

William is spot on. The DVOM belongs in any well-appointed toolbox.



And now, since my truck has begun sooting a bit, I may check my IAT-whatever that is. I'll go read up on it.



If it's not the IAT, then its either the reflash the dealer did, or the JD fuel conditioner I'm running. I kinda like it.

Be careful not to break it off like a spark plug... .



I saw that happen to its more expensive neighbor, the MAP sensor. #@$%! (Only SAW it, glad it wasn't my $50 screw up... )
