Post Selective Catalyst Reduction (SCR) Nitrogen Oxide (NOX) Sensor - EU6 Only

| 1 | Post Selective Catalyst Reduction (SCR) Nitrogen Oxide (NOx) sensor and module |
Only EU6 markets have a single post Selective Catalyst Reduction (SCR) Nitrogen Oxide (NOx) sensor module and a post SCR NOx sensor located in the exhaust system after the SCR catalytic converter.
The Nitrogen Oxide (NOx) sensor comprises an integrated heater and sensor control module. The Selective Catalyst Reduction (SCR) sensor is used to measure the Oxygen (O2) and the NOx concentration in the exhaust gas of a diesel engine. The sensor and the control module are replaced as an assembly.
The NOx sensor control module sends a message via a private Controller Area Network (CAN) bus to the Powertrain Control Module (PCM) for monitoring the effectiveness of the SCR System.
Failure of a NOx sensor or the NOx emissions fail to reach a pre-determined threshold, the PCM will record a fault, messages will be displayed to the driver in the Instrument Cluster (IC) and the Malfunction Indicator Lamp (MIL) will be illuminated.
