Sensor pin 1 and 3 is not shared until it all connects together under the headlight. There are 12 wires behind the front bumper and then 6 running to the junction box. But it is easy to check 1 and 3 by checking for continuity between a good 1 or 3 and the bad sensor 1 or 3.
Swap sensors first, then check for continuity between pin 1 and another pin 1 and then pin 3 and another pin 3 and finally check pin 2 green/yellow between the sensor connector to the junction box.
