x2 for the airflow potentiometer.
Separate the plug just enough to get probes in.
Engine idling: Terminals 1>3 = 4.5 - 5.5 V; Terminals 1>2 = 0.5 - 1.5 V
Engine OFF, Key ON: Terms 1>2, depress airflow sensor plate, voltage increases continuously to 4.5 - 5.5 V

If these values are not obtained, the pot may be defective, or the plug is reversed.
