Thanks a lot from Spain. Your video has been very useful to me. I have a Renault Megane MK3 Sport Tourer with K9K 1.5 DCI engine and DPF from 2014. And several weeks ago began to show the orange light Check Anti-Pollution and Chek Injection too. Some test show a P0471 error, related with exhaust pressure sensor. I hope to solve it with the help from your video.
I have a Renault Megane Coupe 1.4lt- tce 130Hp, with less than 50000 km. I had 2 errors in my screen: 1. Check injection system 2. Check anti-pollution system. Also, the cruise control and the speed limiter wouldn't work. The car lost his power and it didn't accelerate well. The technician saw that there was a hole at the plastic air tube before the turbo. He fixed it, (in about 10 mins) and didn't ask for me any money, even if I insisted. He told me that this was probably the fault because due to the small hole the turbo didn't have enough air - and so the car had less power. He also told me that if this happens again to turn the engine off for about 2-5mins and not to push the car (drive to high rpm). So far so good (it didn't happen again) If it will happen again I will add a comment.
For me, only the check injection system appears, but it appears when I turn on the ignition, I don't have to start the engine..it disappears but in general it remains...1.4tce engine..just the cylinder head was rectified and the distribution changed..Do you think it is the same thing?? I tried to delete the error but it reappears after I delete it.. it gives me Oxygen sensor no passed and catalyst no passed... Thank you!!!
Hey thanks for posting this, I have similar issues, but I cant locate this sensor on Megane 3 1.5dci 2015 95hp, what are the odds that mine isn't visible? also when I search for it(exaust pressure sensor) I'm finding two types one type is plastic black(also labeled as DPF sensor) and other type is as yours with metal part, are those doing the same thing and just different versions or completely different sensors? Thank you!
LM Auto Repairs Thanks buddy, exactly like that I was absolutely soaked 🙁, but it had to be done I was very concerned on damaging the dpf of something else 👍 cheers
I had the same error code few years ago, but for me it wasn't the sensor, it was the pipe that the sensor connects to it, was blocked, took it down and used steel wire to unblock it
Hi I had the same problem with three faults on the dashboard so I decided to replace the sensor as you did on your video. Thank you very much it worked for me too !!!
Hi mate thanks ! I change same thing ( sensor! But version for my car model and year ) and my car work again ... Renault megane mk3 hatchback 1.5 dci 106 hp 2010 and I use Torque app from.my mobile phone for delete all error code ! £26 sensor and £ 3 app ! Thanks
@@CarsExposed and also I change all my disc and pad brake , no to complicate, I order the pieces on autopart.com 4 disc brake fron rear and pad total £ 160 ! Here on the corner the garage charge me £700 + parts ! I savings money mate ! Cheers from Croydon !
I have been suffering from the same messages for years. Check the fuel system and pollution system of my 2013 Renault Fluence Diesel. I want to see the location of the sensor.
@@cooperchen5509 Hi, yes I ended up putting the car in the garage. In my case, the problem was in the air mass sensor and the total repair (diagnostic test, labor and parts) cost around €100. A hug
Had exactly same problem on megane 3 1.5 dci 110 , check anti pollution, check injection , check limiter and cruise control . Found your excellent video and purchased a new sensor . After fudging the wiring connected it all up but problem still existed so did a bit more searching and realised that exhaust gasses have to be blowing at some pressure from the top of the pipe , nothing was blowing from mine , pushing a thin piece of wire down I realised it was totally blocked so a few hours later with the help of some carb cleaner , wire and a battery drill managed to clear the blockage and had a nice jet of exhaust gasses blasting through , put back on the old sensor and everything cleared and working fine . So to sum up a new sensor won't work if there isn't any exhaust pressure . Keep up the excellent videos 👍👍👍
I’ve seen quite few blocked up , generally if you have atmospheric pressure on live data for the exhaust pressure , the pipe will most likely be blocked 👍 thanks for the feedback
Great Videos and super appreciated on the effort - I'm trying to "guide" my pensioner Father on fixing stuff like this from over 6,000 miles away over the phone (he's stuck in Black & White), so it really does help !
Mudei o meu e quando liguei a bateria ficou uma árvore de natal, não dá para apagar o erro nem por nada. Supostamente o erro já la estava antes mas ainda tinha cruise control, agora não tenho depois de mudado. O carro não entra em safe e sinceramente até parece desenvolver melhor, será que tenha feito algo mal e aquilo esteja a não actuar ?
i have had the same problem for a while now, no change in car perfomance, same amber warning lights as you have, polution system and injection system, i can wipe the fault off and it stays off driving around town but if i hit 50mph it comes on again, did your fault do this?,, i assumed it would have been a blocked dpf filter, i put your part code into ebay and there coming up from £17- £35,, il order and give it a try,,,thank you sir
@@gaborkalmar6022 havnt tried yet but will do this week, when dpf filter gets so blocked the car will just cut out,all gases are coming out and no loss of power so i asume this sensor,il let you know
@@gaborkalmar6022 i just bought the code reader from argos about a tenner,wipe the fault off but it does come back when your on the motorway doing over 60mph,good for getting through mot though
I've got a 2013 Megane rs sport 265 trophy and it comes up with check injection system then goes into limp mode. when I ran the scan, it comes up with engine speed sensor signal. I've been having trouble finding this part and fixing the car for a while now so if anybody has had this problem or knows how to fix it please let me know. thank you
The scrap yard would never sell me one because they sell the engine as a complete unit so I ended up soldering the pins to the wires in the end still going fine until now 👍
Been to my mechanic for INJECTOR SYSTEM CHECK, POLLUTION SYSTEM CHECK and exhaust gas lights. Diagnostics reported an error: Lost signal on the air connector. Error canceled and everything works again. Without warning, the cruise control works, the speed limiter works and everything else. Without any errors. The mechanic says that due to the vibrations from the bad road, the contact, i.e. the signal, is currently lost on one of the air connectors.
@CAR EXPOSED Clio RS MK4 getting same message saying to check anti pollution. I have no code reader. I have been driving it for many weeks with this message and car seems normal I think. Just wondering do u know what it is? Should I change the sensor aswell?
Hi Igor. Where are you based? I have been to many garages and seem to be throwing money at the car. It's coming up with STOP and Engine failure signs code 0299. Most mechanics in my local area are charging me absolutely ridiculous prices. Any help would be appreciated.
my megane have DPF problem and I was told told to change EGR VALVE and relay , sensor too . and I did that but again my DPF is clogged in just 5000 km , you have any idea what could be reason in this situation .
Hey man great video! Im having the same problem and im giving this a try and ordered a new sensor. But im looking for a plug the fits on the new sensor and im not finding it. Any help on that please? Thanks
Hello how are you i have a renault megane 3 / 1,2 turbo built in 2014 it shows me exactly the same thing. I've been to two mechanics who couldn't help me. I thought I was writing to you. do you mean that it can also be due to the sensor? ... the megan in your video is a diesel. mhhh I would be happy about an answer. Thank you very much
Hello, my Renault megane iii, 1.9dci shows me breaking system failure, and the engine doesn't start nor crank... what could be the problem? Help please!
Hi i searched for a pressure sensor online and it comes up at £38 wondering how come it was so expensive for yours? Thank you for the video really helpful!
I had same problem but after diagnosis I deleted all faults now only shows these (1) data supplied to cruise control or speed limiter are not correct. (2) turbine upstream pressure sensor circuit signal outside upper limit. What should I do
I have te same message... polution and injection... cars starts and runs fine also cruise is disabled its 2014 1.5dci motor so its possible that i have a faulty sensor also?
I have the same problem cruise control turns off and back on all the time when i drive. Also check injection system light is on. Renault said it could be anything wrong .. that they have to take the turbine and take the engine apart and cost for labor ‘only, is 800€. Also funny part is the warning lights on the dash started to show after Reno yearly oil and filter change. Any tips can it be the same thing as in the video?
My megane does not appear to have that sort of exhaust pressure sensor? Nor do I have DPF (Fap) But the sensors for sale say it fits my car!!!! Anyone got any idea where it may be
It shouldn’t really affect anything starting the car in reverse gear ... if the fault message still there I would suggest to scan the car before any conclusion 👍👍👍
Power on my vehicle is good i did had diagnostic done no fault on still cleared the fault was ok for few days went on long run light came on back again
Just got the check anti-pollution message with engine light and spanner. Megane iii gt line diesel 2015, 42k on clock. Drives fine, cruise control works fine, no other warnings come up.. gonna have to book it in tomorrow somewhere I guess.
My Laguna Mk3 1.5 Dci has the same issue, same fault codes (just minus stop/start) but the sensor on mine is hidden under the turbo up pipe at the back and, Renault have told me there is two sensor versions, so I guess this is what they mean. Looks like I'll have to strip down some of the pipes to figure out which one it is.
Loving your Megane videos. 👌 I have this problem too and have managed to get the new style plug from eBay but now am struggling to release the pins from it. Any suggestions before lose it and start cutting wires. 🤣
Thanks bud I’m glad you are enjoying the videos ... it’s a hit or miss to de-pin those plugs to be honest even with the right tool , if you have a pig tail with the new plug I would just cut it 👍
Just changed this sensor on my 2013 1.5 dci. Got the sensor and wiring adapter off ebay for around 20 quid brand new! My car was giving spurious faults like egr valve stuck open, and unknown wiring issue with low pressure egr...(yes there are 2 EGR`s on this model) had the engine fail light on etc...changed this sensor and everything disappeared.
I have the same problem with my Renault Megane 1.5dci 2013: Check injection system "and" Check regulator and cruise control no longer works.I want to order the part but cannot find the name of the sensor on different websites
Hi . I have Renualt koleos 2nd gen petrol giving me error check injection. Checked with few mechanics all seems perfect as per them but the warning light keeps coming back once ever week coupled with anti pollution bla bla when started . Car drives perfect . Can you pls advise is this also related to same sensor ?
Hi mate just had cambelt water pump and a full service and it's come up on mine ? Haven't had chance to actually look into but was there for around 2 hours now has gone off and has been for few days. Do you think this could have just picked up something was unplugged or do you think I have an issue somewhere haven't seen it since. Would there be a stored code doo you think. It's a 1.6 vvt 10 plate
Ryan Browne The cambelt job and service shouldn’t have affected anything unless they left something unplugged which is very unlikely now that you don’t have any message, I would probably scan the car to check for stored codes that would be a good start... 👍👍👍
Thomas EXOVCDS Yeap the most expensive sensor I’ve ever bought 🙁, but the most annoying part was not being able to connect to my original loom plug... 👍
im afraid i dont have the code number for it, just ask for exhaust pressure sensor connector just be aware renault only sells the whole loom at the time i believe it was £120 cheers
@CAR EXPOSED MY CLIO RS4 PETROL - right now I get message check anti-pollution system. The engine light stays on all the time. But my car seems to drive normal. Do u know what is wrong and how can I see what the error is about? And what should I fix?
Hi I have the same problem on a megane 1.9 dci 130bhp 2012, I took off and cleaned the EGR valve with carb cleaner, I had a leaking injector seal, I therefore fitted a new injector seal which worked fine, I used Wynns Dpf cleaner and I still get this fault occasionally but it does not affect the engine performance it just means I can not use cruise control, any ideas please? Thanks
@@CarsExposed Hi thanks for a quick response, would you suggest I remove the DPF for cleaning? Also where would I find the exhaust pressure sensor? What would be the best method of looking into live data? Many thanks
@@CarsExposed Thanks for the reply. My mechanic showed me the error, it was something like: "injector cylinder 3 circuit fault". He deleted the error and this made "anti-pollution" message to disappear. Could it be from bad quality fuel or most likely I have to replace that injector soon?
I recently got the 'Check Injection system' and 'Check anti-pollution' warnings, but now I am getting an 'engine failure hazard/stop' warning light. I was going to change the sensor as you have but I don't know if the engine failure warning is related. Any ideas? The car runs perfectly and the warning goes off after five mins and may not return until a day or so later. Engine temp never goes above 50% either. Could that sensor be the cause? Thanks in advance for any advice
It could be sensor for sure I did have the engine hazard warning about 3 times before changing the sensor , I used turn the ignition off and on again and the warning would go away 👍
@@CarsExposed Thanks for the really quick reply. I shall change the sensor and reset the codes and see if it clears them all. I'll be sure to let you know. Brilliant videos too. Keep up the great work
The Joys of a Megane. I have a 1.5 DCI Mk 3. I have had the fault code 0670 for a few years now (the glow plug module was replaced in 2018) the car is a pig to start below 4 deg C (A bulb in the engine bay helps lots). I now have the code 0470 with a wonderful Stop message on the dash. My local garage has replaced the exhaust pressure sensor and (apparently) cleaned the DPF. The car drives fine with no stop light on under 2k revs and steady driving. Above 2k revs or harsh acceleration the light comes on. There is no drop in performance and the car really does run perfect. Any ideas as my garage is at a loss.
I have had this problem also a few times, On my 2009megane 3 dci coupe 160000miles I cured mine by cleaning my egr and replacing the fuel filter (at the front behind wheel arch). Not sure but I think the problem is more to do with the fuel filter.
Thaks for the video, I have a 2013 Renault Fluence 2.0 petrol. It shows "Check Anti-Pollution system( low power when eccalarating), it has new coils and spark plugs. I'm not sure if it reqires the new sensor?
Len Paget ah ok, firstly I removed a plastic cover then a rubber seal then I pulled each individual wire/connector with a removal tool ...very cheap to buy from eBay but I have to say they were a bit of pain to push out ...
