Great video, I have a 2.5 tdi be crafter with blocked dpf. On live data it’s showing 0.99 I assume mbar as it doesn’t says what it is but this value stays the same on idle or higher rpm. I checked the sensor and wiring with a manometer and multimeter. On the manometer the dpf pressure is 27 mbar at idle and over 200 mbar at 2500 rpm. Sensor signal wire showing 0.5 v with the sensor connected and 5 v with it disconnected. If I manually put pressure in the sensor the voltage increases but on live data with the pipe connected and engine running is still 0.99. What could be the problem? Thank you! Maybe you have some ideas.
Thank you this is agreat question. The issue here is we do not know what 0.99 actually is representing. That is 🔑 in this question. Also what is your multimeter reading when the engine is idling. i know its .5v connected and 5v disconnected. what is it connected engine running. it sounds to me like the sensor is and wiring are good. Let me about idling voltage then i can try and join the pieces. i love this question
Thanks for the great video but i have a question for u the sensor + signal &ground reading ok but on the scan tool showing that sensor signal is missing dpf is clogged although im getting 1.0 v also pressure on idle showing 7hpa on idle i checked the signal wire from sensor to ecu 0 resistance good continuity Regards
I think your signal wire is open test on the ECU side and compare with the reading on the sensor side. I am assuming you tested on the sensor side. Hope I got your question right
Hi, I replaced the faulty DPF sensor but the diagnosis continues to show P2456 error. The stranger thing is that with the engine off the input sensor shows pressure -202 Hpa. What do you recommend me to do? Thanks for your help.
Where does the service message Diesel particle filter soon clogged come from on a 1.6 HDI engine code 9HZ with a mileage of approx. 200,000 km. The differential pressure sensor reports a difference of 4 mbar. I think it's an electronic error that turned on the service lamp and not the DPF is defective. How can I reset the service light? or is this service message automatically produced at around 200,000 km? Thanks
Thank you for this question. if you have access to a diagnostic piece of equipment, plug it and erase the code if it comes back you know that you have a problem. is your dpf pressure sensor working fine?
Just looking at your video and my son in-law has a renault scenic 1.5 dci with a dpf fault it has been too 5 different people and it's still the same problem he has sent me a video of the voltage at idle and it is 0.49 volts going to 0.59 volts at 2500 rpm as he lives away from me it is difficult for me to help but I think the voltage readings seem very low any advise would be appreciated..
I apologise for taking so long to come back to you Jeffrey. I have been try to source some information from a Renault dealer to pass to you somehow it didn't materialise. Here is my WhatsApp number ring me let's talk maybe I can help out. 00263787382155 please call
There're many things that can cause the signal to be wrong. The sensor, high resistance, ECU or wires. What you do will depend on the causes of the fault. i hope this will help you
Another well explained walk through video, thank you for taking the time to make! 👍🏻
Glad it was helpful!
very simple bravo
Thank you! 👍
Well done 👍 nicely presented
Thank you
Simple yet very helpful and well explained. Cheers!
Glad you liked it!
Wonderful video mukoma. Keep it up
Good job men. Thanks very much! 👍🏻😊
Good job
That's encouraging thanks
Nice video 👍
Thanks 👍
Thanks Sir with the information
My pleasure

nice
Thank you so much
Great information😊 I guess you put your black lead on ur multimeter on the battery or anywhere on chassis ? It shouldn’t matter should it ?
The negative post on the battery is the best but if not accessible the chassis is the way to go. Thank you
Brilliant
Thank you

Thanks for your help.
Did you adapt the new sensor. if you dont have a machine to adapt the sensor clear faults and take the vehicle for a good drive

Please send me the chassis number and or vehicle reg
Thanks very much for your reply I am waiting for my son in-law to come back to me again thanks.
Hello again my son in-law has sent the registration is CV11CBU any help is acceptable.
Thank you I will get back to you as soon as possible

SO if the signal not good. how to fix the signal no correct??? dont understand
There're many things that can cause the signal to be wrong. The sensor, high resistance, ECU or wires. What you do will depend on the causes of the fault. i hope this will help you
what is healthy is it the sensor or the dpf
When the input causes the output to work fine both the sensor and dpf are healthy
