Hi all got code P0470 coming on a vivaro it has done 118k miles but been regular serviced. The description is pressure sensor circut a have changed the sensor as local dealer had said they was changing them under warranty. Van com ing back in next week has any one come across this fault before was wondering if the pipes need changing checked them with light air pressure and all seamed ok. Would be greatfull to ideas before it comes in thanks Steve

Hello Steven, what’s the pressure reading ignition on engine off (obviously should be atmospheric). Blocked or split pressure pipe? (check the metal pipe to the d.p.f.).

Hi
As Alan says, but also check pressures on road test to make share DPF is clear.
