I've had this multimeter sitting in my tool box for a few years now (unused),and want to make sure this vsv (to egr) is dead before I put it in the garbage disposal.
It looks like I'm only getting 3 ohms out of it, and that obviously is no where near 38 - 43 ohms. Am I reading it wrong ? There is a ohms adjust dial on the side of the multimeter when turned all the way up it reads 2.9 all the way down it reads zero.. are you supposed to calibrate it first somehow ?
I checked it for continuity and that passed , is there any reason why I should hook it up to the truck battery at this point and try the vacuum test?
I double bombed at the DEQ today and they looked at my like I was Kim Jong II !!
Has anyone ever fixed one of these little POS.

Try to blow through it both ways without power on it, then try blow with power on.
Some of them act like a one way valve, thats why you should blow through it both ways...

Your meter could be wrong, have you zeroed it with the leads connected together?
 
Well, I just zeroed it ...thanks for the tip. NOW I have a whopping 1 ohm out of the vsv
 
I can't help you with the VSV, but I can help you read the meter. You will notice that the dial selector is turned to OHM X 1K. This means that you take the reading--about 2.8 in this case--and times by 1000. So, assuming you zeroed the meter before taking the measurement, then your meter shows about 2800 or 2.8K ohms.

X2 on this. Cheap consumer-grade multimeters can't reliably read low resistances, thus the reason yours only reads 1000+. You could use Ohm's law (nerd alert) to figure out the resistance but there appears to be other ways to see if it's working correctly.
 
blo thru it both ways. hook up 12 volts to the valve and then blo it again. if there is no change in state, it is defective.
