Fault code 2011 E350 CDI Coupe

[AmericaMonster]

Greetings, everyone.
I saw this error while driving the other day; I would appreciate your guidance on its cause and resolution.
The error number was P2453, indicating that the DPF pressure sensor A is out of range.
I want to resolve this matter before any other issues occur. Thank you in advance.

Verify that the pressure sensor connections are secure and that the holes leading to the DPF are unobstructed. Examine live data to determine the pressure readings during engine shutdown, idle, and elevated RPMs.

Precisely what mersum1es articulates! Examining live data will indicate if there is an issue with the two rubber hoses or the DPF itself. A defective sensor may be providing inaccurate results.

Thank you for your assistance. Could you please indicate the location of the pressure sensor on this model so that I may begin my inspection?
Thank you one again.

It will seem as thus, including two rubber hoses extending from the exhaust to it.

Several films on this topic are available on YouTube, focussing on the bulkhead located to the right of the engine, as seen from the driver's seat.
