Diesel particulate filter problems on a Fiat Ducato

Hi, I own a 2014 Fiat Ducato with a diesel engine and have driven 52,380 km. I have received a fault code P2453-7A which indicates that the engine control lamp is lit, and that the resistance in the diesel particulate filter is low - signal amplitude is less than minimum. What could be the cause of this problem, and how can it be solved? Thanks for your help!

A 2014 Fiat Ducato with a diesel engine is experiencing a fault code P2453-7A, indicating low resistance in the diesel particulate filter. This issue could be caused by blockages or damage in the differential pressure sensor or its hoses. The suggested solution is to inspect these components for any blockages, damage, or improper connections, and ensure the hoses are not cracked or leaking.

Start by checking the differential pressure sensor and its associated hoses for any blockages or damage, as these can affect the readings and trigger the fault code. Ensure the hoses are properly connected and not cracked or leaking. Let me know how it goes or if you have any further questions!
