Abstract
A signal conditioning module for a wide-band oxygen sensor and methods of installing the same. One signal conditioning module includes an electronic processor, a first electrical coupling, and a second electrical coupling. The first coupling is configured to be coupled to a port of an electrical harness. The power is configured to receive an electrical coupling of a narrow-band oxygen sensor signal for providing power to the narrow-band oxygen sensor. The second coupling is configured to be coupled to the wide-band oxygen sensor. The electronic processor receives power over the first coupling, powers the wide-band oxygen sensor over the second coupling using the received power, receives first data over the second coupling from the wide-band oxygen sensor, converts the first data to second data, and outputs the second data over the first coupling to the electrical harness for transmission to an electronic control unit coupled to the electrical harness.
