Peugeot 406 MAF Sensor Problem
HTML-код
- Опубликовано: 5 сен 2013
- I had a problem on the 406 where it felt short of power, but it was not in limp mode.
In first gear it felt fine, but between 2nd and 5th the turbo was late in kicking in, it took until 3000 rpm until it kicked in, which in real world driving conditions meant an awfully long lag period then a sudden burst of power making it not safe for pulling out of junctions/roundabouts or overtaking.
Ive read on the internet in the past the symptoms of a bad MAF sensor, i couldn't see any faults come up on the PP2000 machine and unplugging the MAF sensor quickly cured the problem and highlighted that the sensor was indeed the issue. Thankfully it wasn't anything mechanical.
At first i attempted to clean the MAF sensor with a cleaner specifically designed for these sensors but it did not work, i didn't want to spend any more money after spending £9 for the cleaner. Conveniently i am stripping another 406 for parts, although its a HDi 90 and mine is a HDi 110 a quick check on servicebox shows that the part numbers for the MAF sensor on both cars are exactly the same, i swapped them over and the car runs fine.
Although this wont solve all performance related issues on the HDi engines its very easy to determine if the MAF sensor is faulty by unplugging it, as a matter of fact i drove my car around for 2 months with it disconnected without any problems.
As for the reason for the sensor going bad, i keep my car well serviced but i do spray EGR cleaner in it every year when changing the air filter, i usually spray it through the air filter lid which means it passes through the MAF sensor, its possible that the spray has affected the sensor, but this is only speculation, the sensor is 10 years old and could possibly have just broke. However as a future precaution i will use the EGR cleaner but spray it in the intake pipe behind the MAF sensor.
Thank you so much for posting this. It solved a problem that has been bugging us for years. At least 5 different mechanics failed to find this fault, but your video of the same symptoms and the simple test diagnosed it straight away. Fixed the next day and our 2003 406 has a new lease of life. At nearly 300,000km I had pretty much given up and figured it must be just old and tired, not long for this world, but it's now lively and a joy to drive again. Cheers.
Great to hear that you got the car sorted, 300,000km on a 2.0 HDi is barely run in haha
Many thanks for your videos I had the same issue, no engine management lights on and car was ok but had got very sluggish especially on hills, disconnected the MAF and holy moly what a difference it was alot quicker, I will be ordering a new one today and I also watched your video on how to change the fuel filter but had given up in the past as was afraid to undo the housing without damaging it but watched your video and changed the filter. Thanks again for your informative and easy to follow videos it has saved me money.
+redmikekite Thanks for the comment, glad the video helped
aaaahhh yess! I totally forgot I've run into this problem before... now I almost let a garage convince me that I have to change my turbo... what a shame! :D thanks a lot for putting this up, top work! :)
Muchísimas gracias!
Llevaba dos meses con ese problema (no tan grave, solo lo notaba en marcha 4 y 5...)
Le di al sensor una rociada de spray limpia contactos electricos y problema solucionado.
Da gusto ver una explicación tan completa, felicidades
Thank you, my 406 was lacking power and I tried this. Huge difference in power now. :) Will be ordering a new MAF sensor.
Great to hear that, strange though that these HDi engines run perfectly well with the MAF sensor disconnected.
I think the map sensor if properly broke can cause all sorts of running problems, and it depends on how you broke the sensor, if you broke the pipe coming from the intercooler you will have a boost leak, whereas if you broke the plug it might just be an electrical issue
My Peugeot 406 MDI was very low on power. I took it 2 different mechanics and spent $650 on repairs that did nothing.
5 min on line reading your comments below and the problem was solved.
The car now drives like new. Thank you very much for sharing your experience it was a great help
Thats great to hear you got the problem sorted. I am guessing because you quoted the price in dollars that you are from Australia/New Zealand? The MDI isnt offered here, is it a petrol or diesel engine?
I would recommend joining 406oc, its a very good place for help and advice.
Hi - Yes I am in Sydney. A little annoyed about the money I've wasted with mechanics but very happy that the problem has at least been identified. I am driving around at the moment with the MAF sensor disconnected until the part arrives. The local price for the MAF sensor is about $278. I've instead bought it online from UK at a cost of about $75 delivered to my door.
I really like my 406 its a great little car Thanks again
Which mechanic did u visit, good to know information so we can avoid these mechanics.
Hi John
After getting no joy from Kmart Tyre and Auto in Wahroonga I was directed to a business called Auto Gearbox Services in Hotham Parade Artarmon who apparently had the diagnostic tools available for identifying faults with Peugeots. They put the car on their computer and could not identify any faults but still charged me $98. Next I went to Hornsby Service Centre in Hunter Street. The Manager sounded very confident that he could identify and fix the problem. Instead he performed some type of service that did absolutely nothing and charged me $475. After that I gave up on mechanics and made my own inquiries. I still am very grateful for the information posted on line
Yes I can see you have done the same as most citroen owners have. I also had some work done by Prestige at Atarmon and certainly they do a good job but charge like wounded bulls! The hourly rate is what kills this for most Citroen owners. I do not mind paying but hate overpaying. Same with Carrol at Roseville, good but very expensive! I wonder if there is any feedback on S&G Automotive Repairs at 1/95 Hunter st Hornsby. Another one in Frenches Forest Peter Haremza ?? There again I certainly would NOT pay for services that does NOT resolve the problem. To charge $98 to connect to a laptop to get the fault codes is also very steep. Should be either no charge or max $20 !! Problem too is there are so called mechanics out there that think most people are too naive to know anything, not realizing that the WW Internet is providing us with not only RUclips but Google as well and so yes we can get a lot more information on the repairers as well as the parts we can source from many other sources than just in Sydney only.
hallo,i want to thank u very very very much coz u solve my problem i just change the maf today and it works perfect thank u very much .
Hello great videos i have a 406 90 hdi and white smoke comes out sometimes until fully warmed up ,when driving it in 3rd and flooring it it feels like clutch is going could it be this instead of clutch thanks
Great vid, please keep posting content for the 2.0 HDi, especially for the Peugeot 406.
Cheers!
I will try, although this car has been off the road a couple of years i bought a 2.2 estate and more recently replaced it with a 508 2.0 HDI
However this 406 will be getting some recommissioning at some stage in the future, the car holds quite a sentimental value being my first car, it needs a thermostat housing and a few other bits and bobs.
@@peugeotCitroen2CV Hey man. Great to know that.
Thing is that, the 406 is one of Pug drivers all time favorite. Be it because of the Taxi movie, or just because it's damn sexy car. But there are still quite a few of them left running, just like mine. And tell you what, I'm inlove with her. It's one of those cars, with a soul.
Standartenführer
They just got the 406 right, a good looking car from all angles, and they cope with high mileages and can be maintained easily.
The taxi movies are okay a bit of comedy to them, for me the 406s best moment on the big screen was in Ronin. What an absolute gem of a film for any car enthusiast let alone a French car enthusiast you have them all 605, 406, XM, Xantia even some other cool cars like the S8 and big Merc.
@@peugeotCitroen2CV yep, Ronin had it's moments too. Don't forget the Transporter, 1st car chase, where a 607 was chasing the Bmw - great camera work.
@@CiniMini69
The transporter was another masterpiece of car chase camera work, not sure but there always seems to be something about using narrow french city streets that adds to a car chase.
Although having owned a few 607s including briefly one of the V6 models with the adaptive suspension i don't really think they could keep up too long with an E38, they are more suited to wafting about and long motorway runs, airport taxi in taken is a more realistic role for a 607 haha
i've disconnected the maf sensor and didnt work somebody says i need to clean the agr valve some said the injector,but when i saw ur video i start thinking of the maf coz i have the same problem 100%
DId new MAF sensor solved your problem? I have same problem on my 206 1.6hdi, no difference with or without MAF connected, but identycally behaving. 3000rpm POWWWEERR
Ah thats where the pipe connects to it.
If the superglue fix is holding ok and the car runs fine leave it and then if it does start to give trouble you will know to look there first
egr spray alway after the airflow sensor.
I have an old 106 1,4i or called the 106 xt. It doesn't idle correctly. It keeps reving the engine and sometimes just stays at 750 rpm instead of the normal ~1000. I can see that the idle regulator motor that sits at the end of the speeder cable keeps adjusting back and forth when the bad idling occurs. First I thought that the idle regulator was faulty. But this might also be caused by the maf sensor. When you press the speeder gently in the first 1-4 centimeters it tends to jump. I can sometimes completely kill the engine if I just keep the speeder still pressed down the few centimeters.
I don't know if this Is a problem that you can shed some light on?
Could it be the maf censor?
Thank you!
Is it a fly by wire setup on this engine? On the 1.4 8v engine in my grandparents saxo it has a cable going into a throttle body, you can adjust the tension on the cable with a clip.
great video
did you also had a high idle engine at start up
No the idle was the same as it normally was
Did you get strange sounds from injectors before change maf?
On my 407 with MAF connected it hesitates and dont think the turbo kicks in also lots of soot from exhaust.....I disconnect MAF and it drives fine maybe 10% less power.....I replace MAF with brand new one and no change at all still smoking and hesitant.....I diconnect EGR and still smoking and hesitant i reconnect EGR and leave Maf disconnected and runs fine....Any ideas?
I know this is an old post but I'm betting your new MAF is a cheap one & not a Peugeot one...right?
hi iv just bought a 2004 Peugeot boxer and it keeps going in to limp mode iv put a new fuel filter, air filter, cat/dpf, egr valve and now iv seen your video I'm going to replace the mass air flow sensor but is there anything else it could be?? it starts up fine but as soon as you go to put your foot down the engine light pops up and then it goes in to limp mode I just can't make out what else it could be!!! I will update on the MAF but otherwise if you could tell me anything that would be great
Yes it would help to have it plugged into a pp2000 machine to read the codes see what its saying is at fault
Pls my 306 is not push the air strongly from aircodishener Cooling openings , but the fan play sound is highly, is any filter dirty and can I clean it easily with my self ? And is any video learn how to do that pls ?
I'm live in Iraq , and no good service in Baghdad , with my big respect.
hallo i have fiat punto 1.3 diesel and i have the same problem no powe till 3000 then suddenly booost should i chane thr maf?
I am not sure what way the fiat is setup, sometimes disconnecting the maf sensor will work its a very easy test nontheless
I need to no where the turbo sellanoid valve is on a Peugeot partner tippee outdoor diesel 2014 thanks
Hi, i havent had many dealings with the newer tepee or the 1.6 hdi

Do you have any vids about the P0403 code. I have a EW10J4 2004 peugeot 406 and used this cheap ELM327 obd2 scanner and got this code. It was the only fault code. And it says its the EGR circuit mulfunction. Any tips how to remove and replace it. On this car its 2x 13mm bolts.
Hi there
Not to sure what that specific code means, bar a cursory google saying it relates to the EGR
I never worked on any 4 cylinder petrol 406, just the V6 and only a few jobs
What i would recommend is try a more sophisticated obd fault code reader or even better Peugeot planet 2000 and asking on the owners club
I have a 406 Hdi 110 and occasionally when in third gear , you can feel turbo kicking in then goes sluggish and slow to accelerate , doesn't seem to do it in any other gear , would this be maf related or something else cheers
+loverman2005 Worth trying the MAF as its so easy to test, its most likely something electrical or vacuum related causing this problem.
+peugeotCitroen2CV thanks very much for your guidance , it was indeed the maf sensor , changed it and now it flies ,
+loverman2005 Great job, glad you got it sorted
Thank you I solved a problem
Great stuff thanks for the comment.
Hello. My Problem is Abgas Anomalie.
Dpf Problem?
Greetings from Germany
nice vid
Do you have any idea why my 406 HDi 110 hp sometimes breaks at idle. The engine has not yet switched off. The car has a new fuel pressure regulator. Can there be a MAF or EGR fault? I sometimes have cleaned MAF. The problem is usually when the engine is warm.
What do you mean by breaks? Conks out?
@@peugeotCitroen2CV The engine sometimes runs unevenly. Like getting air etc. But this usually happens when the engine is warm. Sorry my poor English.
@@markol.8173
Hi your english is fine, very good in fact!
A strange one, not an issue i have faced myself but it could be a vacuum leak of some sort.
The best advice i can give is join the 406 owners club facebook page, and post your question on there with the best video you can record demonstrating this issue. There are a lot of helpful members on there and someone who has had a similar issue will be able to help, i am also a member so even seeing the video may help me to determine the issue.
Merci pour votre aide je suis très anteruc.
No probelm thanks for the comment
thx bro
I'm proud owner of a Citroen C5 2.0HDI (year 2003), I have bad MAF sensor too, but I'll replace it with a new one. Also diagnostics show that there is a problem with EGR too, so I'm considering removal and cleaning EGR (I can't find cleaner spray, and maybe manual cleaning gives better results). Can you give some guides how to remove EGR since it is pretty unreachable and it would be much easier if I know where to look for screws.
Hi, I have the same model C5 2003HDI. Just checking to see what you did to resolve the problem? Did replacing the MAF resolve the problem? Any feedback on how best to remove the EGR Valve? tx
The only video i would consider making on the EGR would be if the engine is out of the car, its one of them parts you scrape the arms off yourself to get at on the bigger cars like the 406 and C5 on something like a 307 its even worse.
They dont cause many issues generally speaking on the old DW10 2.0 HDi engine. If you have EGR issues the car will be significantly down on power and make lots of black smoke. This was the case with my mums 2000 Xsara 2.0 HDi. I tried EGR cleaner and the engine had an incident of run away on the cleaner fluid. The fluid also did not really work. In that instance the EGR should have come off for manual cleaning.
In the end i disconnected the vacuum pipe going to the EGR and put a bolt in it, and a plastic cap over the electrovalve where the pipe connected. Solved the problem on the Xsara by disabling the EGR. A cheap and easy fix.
However if you are still interested i have pictures of disassembled DW10 engines showing the inlet manifold and EGR valve. Send me a PM if you want them.
Replacing the MAF was the cure. I also cleaned EGR and it's really hard (removing is hard and putting back is almost impossible), and after all it was OK, so cleaning was unnecessary but I did it anyway.
I have ford C-Max 1600 diesel I have problems with it it is cutting out in the daytime night-time room perfect first thing in morning run perfect run 4 hours at night gay time 5 minutes ticking over cuts out anybody get any ideas
Just proved mine faulty (230,000 miles!) The car also goes haywire when wet, so maybe a replacement will fix this too???
At 230k miles the sensor has lasted quite well, as for the car going haywire when wet, in what way running wise, or the electrics in the cabin?
Tuning going crazy, no power and loads of smoke!
splodgeink Is there any holes in the intercooler piping?
Merhaba ben aracımda turbo basıncı yüksek hatası alıyorum.2.0 hdi 110 lütfen yardımcı olurmusunuz
What is the exact code, is a peugeot planet machine being used?
Bonjour vous le faites en français
And the fixers say it must be open all dashboard, because it is the only way to clean the freeze and aircodishen filter, thanks
The pollen filter is accessed from the scuttle panel, it doesnt require the dashboard to be removed. However the condensor would need the dash to be removed

It does not necessarily have to look dirty to have a fault.
Hello my car my 2000 diesel engines have a problem in my stable 406 tool and these problems are suddenly stop going we could not vehicle on the way to solve Turkey and did not cause cuts fuel does not mean fuel I want to help with this engine from you.

@@cemcem439 Any fault codes? Is it a 110 or a 90? In tank pump perhaps, fuel filter clogged.

Hallo Imam jedno pitanje Dali se kod tebe palila lampi a za Motor i jel pusilo Puno Auto!kod mene na Autobanu crn dim izbaciva i upali se lampa za Motor i nema snage dokse upali lampa pozzz
genius
The engines on the 2 cars are exactly the same. The 110 is just having it`s software upgraded to max. The autoindustri is making several models of cars with the same engine. The software has just been customized to the need of the car models. They save a lot of money because they dont have to invent a new engine for every car model they produce. As simple as that. Thats why you MAF is the same type. You could swap the entire engine and then put the software from the bigger engine into your car and its the same result. 3:53
There are a few other subtle differences between a 90 and 110.
The dual mass flywheel, intercooler and boost piping and i believe the method for controlling the turbos boost. I also think that a 90 used a siemens ecu while the 110 uses a bosch.
There is also talk that the crankshaft on a 90 is the same as an XUD but i have never compared the two in that way.
You wants to eassee upp trying to change gear like colin mcrae.... or you,ll be making another video soon..... why is my gearbox fucked
jamie rodgers Haha your right there, looking at them gearchanges were decidedly abrupt. Normally they change much smoother, the gearbox is still fine. The DMF is due a change soon though, although at this age its done well.

can somebody help me I have peugeot 406 HDI 2.0 i cant start the engine without suport when is start after support then don have any problem I chek everything computer saying in computer no problem but imposible to find the solution i cant start normaly engine
Brake cleaner is also good for cleaning mafs!!
I forgot to mention that engine in my Citroen is the same as in yours Peugeot.
Hi
Yip the DW10 engine is found in the C5, the egr is attached to the exhaust manifold which is tricky to get to because its between the engine and the bulk head, i have removed it in the past but your working blind most of the time and its tricky. If you can go onto service box, or citroens equivalent and look at a diagram of the intake manifold where the egr bolts onto that should help, but i do think on some engines the EGR is held in place with a metal clip which needs to be replaced. wynns egr cleaner is easy to get hold of and much handier than trying to clean it out, although if the EGR valve is badly clogged then manually cleaning it would be required.
