This is super handy! I changed my DPF after inspection it was toast , but now keep getting the risk of blockage coming up, looks like a sensor fault! You're a gentleman thanks for putting these videoes out

Testing instead of just throwing parts - that is the best way..

Good job. Had this myself on a cx130c excavator with isuzu 4jj1 engine. No fault was presented, but went to live data and seen DP not moving. Thanks to your video

Job well done!! Not many like you these days, keep up the good work mate 👏👍

You just saved me €700 from a new dpf it was the sensor keep up the great work👍🏻

Good job dude nice to see someone actually diagnosing instead of firing the parts cannon also some mercs had a service bulletin about changing the connector on the dpf pressure sensor for poor connection there's a pigtail plug available from mb I changed a few when I worked there.

Best mobile mechanic on u tube .

Jimmy been catching up on your past videos keep up great work you do 👍

Thanks Jimmy u are a specialist in this field thanks for sharing all ur knoll age and time,,u are very blessed 👌

a great video im glad i came across your video you saved me from changing my dpf

A great informative video thank you

Thanks for the practical adice regarding the dpf issue, i followed your method and my issue on my Merc Glc is sorted...

Love your videos always learning thanks

Thank you for a great video, very educational and useful ,ohh btw hope that exhaust manifold was 'COLD' bcz you placed your multimeter on it ! otherwise it would have melted away 🙂

your da man jimmy lad 👍👍👍

Thanks for the video very helpful. I have just carried out the same test on my Kia 1.6crdi and my pressure sensor signal wire reads 0.00 at idle and with engine @ 3000rpm. The power wire is fine @ 5v and the ground is also fine. Looks like my sensor is faulty? The reason i checked this is my dpf never seems to regen even after 2k miles.

Nc Lods, Solid infos Thanks

NICE VID!

Great video i always like to check the old part myself but 9 times out of 10 i haven't got the right tools to test it,got a sprinter van at the moment thats got a reading of -47hpa on star scanner checked it last night but haven't got mightyvac to test it,any idea why its minus reading? thanks

Hey jimmy very clever

Usually there is a failure code reporting a short to ground on the sensor, it is extremely useful to be able to read this out yourself.

Now that's what you call a machanic!

Hi there this is a very helpful video. I’ve got a Astra 2.0 cdti A20DTH 13plate, my dpf sensor is reading 0.41v at idle but also 97kpa ? My reader isn’t picking up any errors and car drives fine. Could it be that sensor voltage is normal but it’s been replaced at some point but not relearnt via diagnostic tool? Thanks

My 2011vwpasst is surging in revs in high gears and when I activate the cruise control, I'm getting codes for secondary air sensor, o2 htr monitor sensor and o2 sensor , could a bad exhaust pressure sensor trigger all these

Great video Jimmy what would be the life span of this particular part ?I guess it would be the same for most brands of car ?

Been watching a few of your videos lately, hope I can get your opinion here… I am a home mechanic with a 2009 Audi A6 3.0tdi, 293k km, no mods other than a simple remap from a known good tuner: P242F stored, can be deleted but comes back in no time. No other faults stored. Been smelling exhaust fumes for a while now, but can’t find an exhaust leak. Exhaust tips still clean as a whistle, high fuel consumption (9,5L/100km) but no change in power. What do you think, best scenario split dpf sensor hoses? Or a worst scenario clogged dpf causing backpressure causing gasses to escape pre-dpf past a gasket?

Great stuff!

Very good video , you explained very well. I have a question, i have a glk x204 220cdi 2011 and it has 118000km . Today i have changed oil and filters and i have also changed diesel filter . But after that when I completed the service, I went for a try but it seems car have to power and i turn off the car and started again and come engine light on . My obdi shows P2454 dtc sensor A . I thought maybe i just bought the wrong diesel filter and i have removed and installed the old original. But the problem continues. Can you please help me ? Thanks

Bravo! man you need a head cam so you can use both hands great video! What is that plier called and can you use Pipe Hose Clamp Clips instead of these weird fasteners....

Do you know if it is necessary to reset the ECU once you change the DPF with the scanner or a regeneration to get the new values from the differential pressure probes?. I have to change it for a new one, it is very saturated.

Good job

amazing job!! may i know the autels model?

Hi i got p244a00 error code on my w212 facelift and thinking about changing sensor. But is there other things to do after changing sensor?

What about calibration of the new sensor? I found there an option for that but i have to put a min and max value

Where possible I try use main dealer sensors. However considering they all work the same in principle the price of these sensors varies massively

hello if you can help i have a 2006 mazda6 dpf problem. i replaced the filter and sensor and it keeps my dpf light on still no traction?

Hi, on this type of dpf sensor is air supposed to travel through it ,like blow it trough one end and comes out through the other one ?

Can you help me I have a 1.6 tdci diesel Ford Focus it’s had the edr changed out into diagnostics and it came up with glow plugs they’ve been checked there all fine then the mechanic changed around the relay it worked for around 2 min then went straight back into limp mode the light is on and I’m pulling my hair out do you think it needs a new relay switch???? I hope you can give me some advice Thankyou Adam

Excellent i was looking for some answers to a few questions that you answered for me, thankyou.

I just done today for 2 times the Passive DPF regeneration with the same tool as yours and it came back both times:failed. I have a 2011 mazda 3 2.2 diesel. Do you know why cames back as a failed? Thanks

Wen fitting a new dpf sensor dou need to recode it in or just clear the codes mercedes vito w639 thanks

Hi! Scope signal wire on smart fortwo cdi and see 0.5v to 0v wave on sensor connect keys on engine off. With unolugged see 0v on signal wire :/ ... Its not supposed to see 5v on disconect plug and steady voltage on conecting plug?

What code reader model are you using? Looks a good bit of kit

Hi 👋🏼 everyone . Car om642 ml350 has loss of power / limp mode as well revs high no codes , possible dpf full or pressure sensor ?

Good video would you have a link to where you purchase Mitty vac

Hi. On a G30 2.0D, i get 2BB400 Ista error code. Check engine on dof regen, regen succesfully, the car has no problem, but the check engine appears again after a new regen o dpf. Have an ideea witch sensor is the problem ?

Good Job. l have a question, why where you testing one side of the sensor?

Too good

Can you recommend anybody in the Staffordshire area please? DPF blocked limp mode activated in a honda CRV 2010. many thanks

My Vauxhall zafira 1.7 reading Dpf pressure sensor on idle goes from 0 to 1 is this correct saturation is 42% but my car keeps doing a regen every few days? Help please

Is it possible to fool the ECU into thinking that the FAP is installed through the differential sensor?

Hello, how are you? Can you help me? I have a 2016 Range Rover Vogue, a diesel while driving. There is a warning sign. Driving is restricted.

Good work 👍

Can you fix my van, check anti pollution system, check injection system and engine failure hazard on. Help

So will the volts increase or decreasing on the sensor wire? My base voltage is 1.2 and when I add pressure to the small hose the voltage increases. When I add pressure to the large hose voltage decreases.

When with pressure sensor fail obd 2 tool detects p244a error? Thanks

Would this cause it to over fuel by trying to do rgens and failing? Tia

Hello there voltage on my pin is 1.7V instead 5V what should I check?

Is it a p2002 code?

Are you supposed to be able to blow through the 2 hoses to check for blockages?One on mine is barely passing any air.Can you safely run a wire down them to clean or is there something that maybe damaged.Too hard to remove them as they're at back of engine and hard to get at to unscrew.

Great video .. . If say a car IS regenerating but to often can it still be this? Other question..that scan tool u have will it do injectors on a mazda ? Ty in advance

nice

Cheers lad

What are the signs of faulty dpf sensors?

Anyone going through DPF clogging issues - I can recommend doing a backpressure test with ISTA software, there are tutorials on youtube. Helps understand how badly clogged the DPF is and also shows the readings of this sensor - if they are the same across the range, sensor is faulty. For me, turns out the pre-DPF temperature sensor is at fault for regens not happening, showing 7.9 degrees celsius with the engine running - impossible.

Hi i have a toyota yaris with engine management light on code: p2463 which is the DPF soot accumulation after cleaning the dpf car works fine but after 3 days the light came back on again any where i take it they just say that i need to change dpf which im sure its some thing else any idea to help me please.? By the way none of them uses the equipment that you have. Just the dignostic computer .thank you

So how do you do it at home. Kit looks expensive

Hi, I have a mini 2.0 SD and the reading on the Diff Pressure sensor is 342 mbar with ignition on and engine off. A new replacement sensor reads 352 mbar with engine off. Should the pressure read 0 with the engine off? If i disconnect the sensor it reads 299 mbar. Thanks

I have a 2019 S-max diesel with a P2002 error. Ford says it needs new injectors and a particle filter. Any hints on how to diagnose this, Ford claims it doesn't have a dp sensor.

how do you know which wire is signal wire, positive or ground when you connected your multi meter?

Jimmy, just subscribed mate... are the smoke detectors worth buying - do you use it much? Cheers Gordon

Hi O'Rileys , I have reading on differential pressure sensor in minus. When idling it is --9 mbar and when is not idling it is -300 mbar.Can you help me why the values are in minus ?

Hello,please help.I have 2 fault on Skoda Superb 2.0tdi 110kw 2016y. First one is the : P164E00 Second : P245200.Are they conected erors or 2 diferent fault's????What to do???Thank's

My XC70 2.4 D5 is still showing a DPF sensor reading of 0, sensor all fine. Can’t work it out.

My sensor is showing 3000mbar at idle and up to 11000mbar when accelerating. And the dpf is cleaner recently. Just regens often. 100km. I quess its time for new sensor.

Hello friend What can cause if no reading showing on live data under diesel particular filter differential pressure sensor b28/8

❤

I have S350 where is the sensor located @?

hi iv been looking after my cars for year but this code keeps popping up p245328 the input for the dps 1 in the diesel is faulty the signal offset is outside the permissible range. sensor works fine please heeeeeelp ps its the same car as here

Hi, is the dpf diferential sensor different to an exhaust back pressure sensor?

plug in the new oxygen sensor or Lambda probe into the car installation connector not built into the Dpf filter that connects it to the car's electrical system and disconnect the cable from the old one that you have built into the Dpf.... A miracle will happen. All errors and lights will go out.. ..The computer in the car, through a clean air sensor, reads a clean air flow without CO2 and turns off every single Error exactly that the same dirty 0xygen sensor reads in the old one that is on the Dpf.....You bypassed the complete system of all sensors and Shit with that move😅

I change sensor bosh and not working then one guy from mercedes says i must buy original mercedes is thet posibile?

Where are u located?

I always pronounced it "mighty" vac, but then again, I'm American. 🙂

oh god... If i find out it's just the sensor after having replaced DPF, fixing exhaust and etc... 🙈🙈 oh well, will be more wise.

is 5Vdc not the supply not the signal

Merci mais tu parle trop vite 😀

Mercedes Benz...modern garbage

Hi, i have checked my car Audi A3 2016, and it has two seperate sensors next to each other, both have two places for two hoses on each, but only one side is connected on each sensor, both connected on the left hand side, would you know which one is before the DPF to put the DPF cleaner down?. I don't have any errror codes as have scanned the car the first day i got it, but want to know for future refernce and will be travelling a lot of miles after Christmas, thank you best regards

Great job Jimmy .but I bet u don't drive a diesel car most mechanics around here drive petrol cars now or Hybrid cars.

My dpf light has gone off because I took it for a long drive on motorway but now I've noticed my fuel Is getting used up very quick
