ford mondeo 2.0 tdi how to reset engine managerment unit code

ford mondeo 2.0 tdi how to reset engine managerment unit code p2002

P2002 = DPF efficiency poor (Diesel Particulate Filter Efficiency Below Threshold Bank 1) so exhaust pressure sensor has detected a blocked or blocking DPF or its a faulty sensor.

if the ECU thinks the DPF is blocked then it won't allow full engine power so I'd suggest;

taking the car for a long drive where you can keep the engine rpm up over 2000 rpm for around 30 mins this will get plenty of heat into the system and get the system into re-gen mode

if that doesn't help then consider

or even removing it completely as you'll still pass MOT's fine without it, the key thing is to have the ECU re-programmed so its no longer looking for it


On cars where the DPF is removed then typically you get more power and more mpg as it restricts the exhaust even when new

I already had the AA come out and regenerate it but it only lasted a day. If driving it on a long journey doesn't work, do I have to take the car to a ford garage or can any garage remove it?

Hello Steve

any garage should be able to reset the code

however if its a genuine fault then it'll just keep coming back and it may be a faulty sensor

I'd try the 30 minute hard drive and see how you go from there
