I changed the upstream nox sensor of my peugeot 3008 bluehdi 1.5 2018 vehicle due to dreaded P02EE error code.
However ,after driving the car around to get the nox heated up to optimum range ,i still notice the upstream sensor live data didnt deviate from 0 value regardless of speed just like the previous one.However downstream shows activities depending on engine speed unlike the upstream sensor ( image attached) .
I need anyone conversant with this upstream sensor live data to confirm if 0 value is normal for this sensor at heated stage as i have seen some forum member with similar experience of having zero reading on their upstream nox sensor while fully heated .Can anyone with similar car ( 1.5 blueHdi ) check and confirm this for me please
