Hi folks, new to the forum. I have a UK 2006 2.0 Diesel Mazda5 and I have a fault code showing a fault with the exhaust differential pressure sensor, which is the one for the DPF, right?

Does anyone know the part number or where to get a new one from, because neither GSF or EuroCarParts seem to have one listed.

Secondly, where the hell is it? I've followed the two pipes up from the dpf as far as I can, but I just can't see where in the engine bay the sensor actually is.

Any help?

 

What diagnostics have you carried out to conform the sensor?

What fault code are you getting?

Has it had a oil data reset carried out?

Has it had a "forced" regenertion

 

​​​​​​Hi, its had the oil/service indicator reset. It had a new dpf about 6 months ago and has been ok up to last week. The code shows high ash accumulation which is putting the car in limp mode and preventing a forced regeneration. I've tried clearing the code but it comes back after a minute or so of driving. Its only ever run on good fuel and mobil1 oil for
dpf cars, so can't believe it's full of ash already so wanted to investigate pressure sensor first.

 

it's located up in the actuating secretion solenoid and around the corner. In order to get it out you will need take a can of wd-40 and spray it up in the tail pipe. After running the engine for a few mins the sensor will literally projectile out at you so beware. In all seriousness the UK/diesel guys really need a separate forum topic as it seems like a completely different car.
