Yours may be different, but in the SM for a '91...

Use a voltmeter and back probe the connector while still plugged into the sensor on the vehicle with key on, engine off.

Should be 5 volts between pins A and B with key on, and roughly 0.5V at idle position from pin C to pin B and roughly 5 volts at full throttle from pin C to pin B.
