This fault code is stored when a malfunction is detected with the NOx Sensor circuit. Some lean burn and direct injection vehicles will use a Selective Catalytic Reduction System (SCR), which uses a NOx accumulator to store oxides of Nitrogen and allows them to be reduced at a suitable time. A NOx sensor is used to detect when a regeneration is required and when the regeneration is complete. The NOx sensor will have a module located close to the sensor which communicates with the engine control module. A heater circuit is required to get the NOx sensor up to operating temperature quickly to allow for reliable performance in a timely manner.
