all you need is a voltameter.
to test the camshaft sensor, turn the key on and check the supply voltage at terminal number 3.(should be around 12 volts)also check #1 to be sure it should be 4.8-5.2 volts
crank sensor is the same but check terminal #2 instead of #1.
also check terminal #4 for constant ground.
hope this helps...let me know if you need that clarified at all!
