SENSOR DE NOX 2 ( SAÍDA )

Technology and operation of the NOx-2 sensor (output), its electronic architecture, and physical positioning in the Euro 6 after-treatment system. Use of the Cummins INSITE diagnostic tool to form the diagnostic group related to the NOx-2 sensor (output). Readings and explanation of all parameters related to the NOx-2 sensor readings. Step-by-step explanation of how the after-treatment management system connects the NOx-2 sensor throughout the heating of the entire exhaust gas treatment system. Reading and explanation of all operating phases and their parameters, and how they behave during heating. Disconnection of the NOx-2 sensor from the after-treatment CAN network, verification and analysis of the generated faults, both root faults and consequence faults. Reading of parameters with the NOx-2 sensor disconnected and interpretation of the strategic values ​​assumed by the engine management ECM module.
