T1009 Posted April 5, 2018 Share Posted April 5, 2018 I was away over the harsh winter period and on my way home the engine light came on for dpf high soot and into limp mode. Before I have put wd 40 into the pressure pipe entry and this sorted it out, not this time, very little smoke came out. I confirmed the vaporiser has continuity and was not blocked. I reset the codes with pipes detached, still there. Reset with senor detached from pipes, still there. This lead me to believe the pressure sensor was faulty. Today I fitted the new sensor but the lights still come on. Cleaned the dpf using a dpf cleaner but lights still come on. So I tried a stationary regeneration but had hardly any smoke. Soot was at 207% before and after the regeneration, surely this should go up or down? When I reset the codes they come back on with just ignition not engine on, is this normal? Also when disconnect the pressure sensor and reset the codes. I get high voltage code but I also get live readings of soot 207% still? Could I have a short? I get continuity on the sensor plug even with the negative one the battery disconnected? Quote Link to comment Share on other sites More sharing options...
