Question Asked: 

Have 2001 Ford Escort 4 door sedan. The check engine light was on, hooked up car OBD II to laptop using Autotap program for reading codes and real-time sensor outputs. Both O2 sensors read 0 MV. Replaced both O2 sensors with new Bosch units and cleared fault codes with program. Both new O2 sensors still read 0 MV. Changed out front sensor with another new Bosch unit and both still read 0 voltage. Tried new computer and still no sensor voltage. Rang out harness wiring and found no opens. Can't get car to complete emissions check without O2 sensor reading to pass state inspection. Car runs great
