Ford 2.0 TDCI P2002 Error: Orange Check Light & DPF Regeneration - Replace Sensor or Risks

If the orange chek indicator lights up and it turns out to be a P2002 error after the diagnosis, do not delete it every time it comes back, and it will come back for sure.
When the message appears, the ECU shortens the distance to the next DPF regeneration to 150 km in order to protect the engine from clogging the filter. If you delete the error, you automatically extend this distance and this may lead to the actual clogging of the DPF. This cycle can last up to 5,000 km, after which the ECU puts the car in a state of failure, cuts off the turbo and you can drive another 200 km, then the car will stop and only the tow truck. Do not hesitate to replace the sensor, because frequent regenerations lead to the penetration of ON into the oil and an increase in its level, which, if uncontrolled, may lead to its seizure.
Sensor inspection:
Check the rubber hoses on the DPF side for blown, because they are close to the exhaust pipe and may have come off the corroded, barely sticking clamp and touch the hot pipe, if they are ok, remove the hoses from the sensor side and blow with a compressor. If everything is fine, connect to the FROSCAN computer or have the sensor operating value diagnosed by a specialist. The damaged sensor will show 0 kPa at idle and when adding gas.
Think carefully about buying a new sensor, it must be original with the word FORD, no other, the new replacement will not work, only further nerves and problems will arise, such as error P2455, where the ECU informs about a high voltage value, or a short circuit, or a damaged or dirty connector. And all this is nothing more than a faulty new replacement, which will mix you so much while driving that you will start browsing the installation, replace EGR, Turbo, DPF and the error will appear anyway.
A properly functioning sensor shows values at idle speed of 6-7 kpa (constant without any fluctuations 1-20) and the maximum value at 5,000 revolutions is 150 kpa. You do not have to burn the filter statically or put it into washing, after installing a good, new ECU sensor, it will determine whether it needs to be burned in 100 km or 800 km. Static firing will only shorten the life of the turbocharger, if it can withstand it at all.
Don't worry, it's just the Ford [/ syntax]

Burnout of the particle filter solids, or the scythe with the computer blocked, if not 3500 rpm, a long distance to burn out. In some models, a refrigerant container is mounted, which is fed to the FCS, but if you drive at 3500 rpm or slightly above about 10-15 minutes, the problem disappears. PS DISEL does not like city driving, most users do not remember to chase the bastard off once every 2-3 weeks for a long distance.

Hello
I came across this thread because I currently have a similar problem in the 1.6 TDCI engine Mileage is about 250kkm.
Well, it throws me the P2002 error. Earlier, I had the turbine regeneration done due to excessive backlash and professional DPF cleaning (FAP).
Now the value from the pressure sensor is actually always 0.0.
But after connecting the hose from behind the DPF to the pump with a pressure gauge and sucking in, the computer showed 40kPa, which roughly corresponded to the pressure gauge (-0.4bar). On the other hand, apparently on the pressure connector before the DPF, the positive pressure connection did not give any indications. I did not look closely at it.
As an electronics engineer, I found that if the computer value is 40kPa and the pressure gauge is -0.4bar, it looks OK.
Previously, this sensor was replaced with a used one and it generally showed the same, i.e. 0. When connecting the hoses, there was an indication for a moment. Not more than 10.0kPa and it was falling to zero quite quickly.
The pressure was also measured, upstream and downstream of the DPF relative to the atmosphere, and there was no noticeable increase there.

I wonder if the sensor is really broken?
It's a bit strange that the differential sensor can work on one port, but not the other. I explained it to myself that if the higher pressure port is clogged inside the sensor, and the processing is only positive difference values, it gives a zero result on the output.

If I could check again now, I would connect this pump with a pressure gauge again to both ports and compare the results, pumping to 1.5 bar on the positive and as much as possible on the negative, and comparing the indications from the computer.

The plan is to have a reliable sensor replaced or used.

I am asking for opinions

Update
It turned out that the hoses were mixed up after cleaning the DPF / FAP. After replacing, the sensor shows something, but in the range of, for example, 0.2 to about 10 kPa when driving at high revs. But so far the error has not popped up. Can there be such small indications?

Regards

Hello, a very helpful description of this error 2002 in my case turned out to be a broken hose from the DPF sensor

I am just facing this dilemma.

I have to choose between an original FORD for £645 and a replacement BOSCH for £254.

The difference is substantial. After all, BOSCH is not some bogus company.
Should I really be afraid of a BOSCH sensor?

No need to be afraid, you will only lose 254zł
actually, the fakes in this car don't want to work as they should because it's a ford, after all

Well that's an interesting theory, thanks for the info.
The situation with me was this - the car (Ford Mondeo 2.0 TDCI 163 hp, 2014) suddenly choked, slowed down and an engine fault message popped up.
When connected to Forscan, it showed error P2002 Particulate separator performance below threshold (cylinder row 1)

I checked the sensor parameters both at idle and while driving.
1. at idle it always shows 0 kPa
2. at steady speed shows 4-5 kPa
2. at higher load e.g. driving uphill on the road (e.g. overpasses) it jumps to 7-8 kPa

Percentage of DPF full after driving about 60 km increased from 50% to 64% (there were no symptoms while driving, it drove evenly and accelerated well)

In the first post it says that if the sensor is banged it shows 0 both at idle and when adding gas. On the other hand, with me, the reading increases when adding gas.

Is it actually the sensor to be replaced?

I would also add that the hoses have been checked and are unobstructed.

Please help.
