How do you fix p2453 error code on 2009 Mitsubishi Lancer

P2453 comes on after a long run on Motorways. On clearing code it will come on again within 10 miles. I've used particulate filter cleaner and high rev runs and does clear the problem, but it keeps returning. - Any ideas . It seems to be opposite to other DPF problems

It is a 2009 mitshibushi lancer 2litre diesel. The actual dpf warning light has only come on once, but this engine management light is recurring. It is related to the differential pressure sensor.
