The vehicle is a 1996 legacy.

with a 2.2l motor............

 

I would like to test one... say with an ohm meter.....

One of the connection pins should tie to the wiper contact of the variable resistor and another pin should tie to the end of the resistor. By placing the meter probes on those contacts and moving the throttle position arm you should see the resistance change on the meter. Sometimes bad spots can happen on the resistor and the sensor should be replaced.

See attached.
