Checking Camshaft sensor, map sensor
 

Is there any way to check if a map sensor or camshaft sensor is good with it off the truck? Can it be checked with a meter or any other way? I have a couple used ones and would like to check them out with out having to put them on the truck. The map is not so bad but other sensors are a little more trouble to get to. [eyecrazy]
