Sometimes it's useful to test a sensor with a 5 volt input rather than resistance. Ford tests sometimes call for a 5 volt input to test output to prove the sensor.
I constructed the below tester with materials I had on hand and a voltage regulator I purchased from Radio Shack. It's crude but works. It allows me to connect the tester with alligator clips as I used standard automotive connectors with rivets and no soldering. Get as fancy and sophisticated as you want.
You can use your 12 volt battery or, as I have, a 12 volt power supply to get the input voltage.
