If you have DTC P0030 set, measure the resistance
between terminal 3 and 4 (middle terminals) in the
connector for the front sensor.
The reading skould be 3 ohm if it is ok otherwise open circuit.

Rather than wasting a lot of time with the rear O2 sensor, just get a new Bosh with the correct plug. From what I can tell, the front and rear sensors are the same except that the rear has longer wires.
