Hi im kevin this code doesnt refer to the dpf filter its saying that the front temperature sensor is outside the permitted range .this normally indicates that the temperature sensor has failed

Hi,Thanks for your response.
Is "Nissan Part no. 22630EC01A" the correct type for this error code?Max

Kyes this is the correct part number

Customer: replied 2 months ago.
Because this part has also been replaced after changing the filter.
I guess replacing 22630EC01B will also not solve this issue?
What else could be the problem?
This is an important issue because the car goes into emergency mode all the time.
After changing the filter the Software has been reset.

You need to check the live data with a diagnostic tool and see what the temp sensors are doing there is more than one amd the need to read within a specific range dependent on engine temperature .i believe you have a wiring issue on the temp sensor that will need to be traced back .normally one of the temp sensors will quite obviously be very different to others

Customer: replied 2 months ago.
What diagnostic tool can supply the live data of the sensors?

You need a nissan specific tool

Customer: replied 2 months ago.
Would this be available at every nissan dealer?

Yes it would the tool giving access to live data will help pin point the issue as to weather its a wiring issue or a bad sensor
