Yes. A TPS is just a potentiometer.
Low ohms with throttle closed and high with it wide open, or vice versa, depending on what kind of mood the engineer was in that day.
The key is the resistance steadily changes as you open and close the throttle, and does not jump around erratically or have opens or dead spots throughout its travel.
An analog ohmmeter is very good for finding problems with pots. The needle should always move steady and smooth. If you see it jump, spike or suddenly fall to zero as you are moving the throttle, replace the TPS.
