Yes, since the signal wire from the sensor itself has been intercepted, the ECU is reading the voltage that the sim is putting out, and not the voltage that the O2 sensor is reporting when it measures catalyst efficiency. So it doesn't matter if the sensor is plugged in or not. It just has to be in the wire harness.
