Pretty sure the integrity of the 2 wires between the sensor & the ECM are good.
I get 12 volts at the ECM side with the sensor unplugged! Plug it back in & it drops to 2.3 volts! YES you would assume the sensor is shorted or open circuit but it works when connected on the O/S front connector.
There is a slight resistance reading difference between the N/S front & O/S front sensors but I don't think it is enough to cause a problem
No voltage drop from 12 volts if any of the other 3 sensors are unplugged!
Looking like the driver for the N/S front sensor in the ECM is Kapput
