| http://www.w3.org/ns/prov#value | - We are proposing that the OBD system monitor all exhaust gas sensors (e.g., oxygen, air-fuel ratio, NO X) used either for emission control system feedback (e.g., EGR control/feedback, SCR control/feedback, NO X adsorber control/feedback), or as a monitoring device, for proper output signal, activity, response rate, and any other parameter that can affect emissions.
