1. A signal conditioning module for a wide-band oxygen sensor installed in a vehicle, the signal conditioning module comprising:

  • an electronic processor;

    a first electrical coupling configured to be coupled to a port of an electrical harness, the port configured to receive an electrical coupling of a narrow-band oxygen sensor for providing power to the narrow-band oxygen sensor, anda second electrical coupling configured to be coupled to the wide-band oxygen sensor,wherein the electronic processor receives power over the first electrical coupling, powers the wide-band oxygen sensor over the second electrical coupling using the power received over the first electrical coupling, receives first data over the second electrical coupling from the wide-band oxygen sensor, converts the first data to second data, and outputs the second data over the first electrical coupling to the electrical harness for transmission to an electronic control unit coupled to the electrical harness.
