The majority of Cummins engines are equipped with two NOx sensors to measure the NOx emissions. One sensor is located on each side of the SCR. The upstream/inlet sensor measures NOx levels before the SCR so that the ECU can know how much DEF it should inject. The downstream/ outlet NOx sensor checks NOx levels after the SCR. This combined data is used by the ECU to check if the SCR works and determine if it needs more DEF. This data helps the SCR to reduce harmful nitrogen oxide particles from your exhaust.

Cummins NOx Sensors are extremely sensitive parts that measure fluctuations in microscopic particles of NOx in your exhaust. As with any delicate sensor, even a slight amount of damage or contamination will cause NOx sensors to malfunction. The ECU can detect data inconsistencies and generate a DTC when multiple parts are interconnected. Cummins sensor failures are often caused by soot from other emission-related components. The nitrogen oxide sensor can be inaccurate if soot from the exhaust is clogging it. The result can be that too much or not enough DEF is injected before the SCR. Here you can learn more information about what is a NOx sensor and how it work.
