Hello

To any one who may help! The particle light is on on the dash the fault code is p2002 particle trap below efficiency threshhold.engine is in limp mode and will not rev above 3000rpm it is also flat when revving to 3000rpm, the particle pressure sensor has been renewed and the pipes checked to be clear, the pressure sensor is out putting .6 volt which i think is showing no blockage. The ash mass is 43% but yet it stays in limp even when put on a motorway? Any sugestions?
