Code P2098 Audi Description
The Oxygen Sensor After Three-Way Catalytic Converter downstream of the primary catalytic converter supplies the Engine Control Module (ECM) with a voltage signal (nonlinear) indicating rich or lean. If the primary catalytic converter is supersaturated with oxygen (lean mixture), Oxygen Sensor After Three-Way Catalytic Converter will send the Engine Control Module a nonlinear signal indicating the lean mixture condition. The mixture is then enriched with fuel until the oxygen has been displaced from the catalytic converter. This condition, in turn, is registered by Oxygen Sensor After Three-Way Catalytic Converter as a nonlinear signal indicating the rich mixture condition. The mixture is then leaned out by the Engine Control Module. If the nonlinear signal is received again, the mixture will again be enriched. The frequency, or period, during which the mixture is enriched or leaned out is variable, being dependent on the gas flow rate (engine load) at that moment.
The Oxygen Sensor After Three-Way Catalytic Converter contains the following components: The Heater For Oxygen Sensor 1 After Catalytic Converter and the Oxygen Sensor After Three-Way Catalytic Converter. Components cannot be serviced separately, it must be serviced as a unit.
The Diagnostic Trouble Code (DTC) will set when the Post Catalyst Fuel Trim System is not to factory specifications.
