You should get 150 to 300 ohms but it's a shielded signal measure ohms between the pin and ground.

Dubious it’s user error. I know how to follow the FSM and read resistance. Unless I’m not understanding the conventions on the pin numbers and color conventions (thick black vs thin black lines)????
The values are different than what you state for an OM603.971, depending upon the sensor (not sure which I have).
I don’t have the special three way diagnostic connector, so I can’t do 7.0 or 7.1. But I’ve done 7.2 thus far and not seen anything.
