I have a Peugeot 207 1.6 VTI - the antipollution fault could be related to either a head gasket issue or ECU issue, mine appeared for a day then disappeared the day after, I believe I have a vacuum leak in the intake system somewhere causing the miss fire (the engine shuddering + shaking) the antipollution fault is caused due to a bad air/fuel mix ratio so recommended fixes are - look for vacuum leaks, inspect spark plugs (these need to be changed every few thousand miles), look at the fuel injectors (have them changed if necessary) get a mechanic to look at the coil packs too (these are known to fail on the 1.4 and 1.6 petrol engines ) if nothing else works look at the PCV valve(this is responsible for regulating the blow-by gasses in the engine and put them into the intake system if this gets clogged or stuck could cause values to be off therefore causing the fault) get this replaced if necessary, hope this helps people.

This solution worked for me 🎉. Thank you so much! After the fix I needed to reset the Engine Control Unit (ECU) to clear the warning message. You can do this by disconnecting the car battery for a few minutes, then reconnecting it.

I have a citroen 1.6 VTI and used this video it works 100%

If you drive your car more likely for short distances then engine will not get hot enough to start the regenerating process to clean the cloged particulate filter resulting in a antipollution fault. Drive your car to a motorway or empty dual carriage way (best in nights). The temperature meter should be showing above 60°C when you begin with this process. Place 3rd gear and drive your car at 3000-3500 rev /min for 15 to 20 minutes to let the ecu to kick the regeneration process. Keep driving car for 15 minutes in this state will be enough to clean your catalytic converter and your problem will be solved. But if it doesn't then the problem is with your catalytic converter and more probabily you need to change it. This worked for me 100%

absolutely Brilliant!!!! Thank you so much!!! Happy New year!!!!

Good fix but that is not a sensor, it's a solenoid valve used to divert oil flow. Don't know what it does there but I have come across them many times in hydraulic systems.

Hi I have the anti pollution fault coming up together with the fault codes P0341,P0342,P0343(camshaft position sensor). According to the service garage the two sensors are ok. Could this be the solution to my problem? I have a 207cc b.t.w and I have that sensor you are referring to.

Does the 1.4 diesel version have this sensor do you know? constant anti-pollution warnings on mine

Was this causing a misfire mate? If so what cylinder?

This was great help man.. I got similar error & this video was great help.. you saved few hundred bucks for me 😂😂🙏🙏

thats a VVT valve - hydraulic valve to adjust cam timing - if its blocked and not adjusting the timing correctly the engine will be running ineffeciently , bad burn rates

I have this same problem with my wife's 2006 Peugeot 307hdi, get the anti-pollution warning come up (except it's in French) but the engine light is constantly on no flashing, would that be the same problem, ie sensor etc?

How much would you charge to fix something like this. As well as low revs? I feel like some places over quote when a woman brings in a car.

FYI, I did this as I got Antipollution Fault on our Citroen 2010 1.4VTi 95. Unfortunately it didn't fix the problem. My code was P0343, Sensor circuit high, camshaft A (close to windshield). I swapped the sensors (as they are the same) and the error code now pointed to sensor B (close to front bumper). As the fault followed the sensor I swapped the sensor (31€) and all error were gone.

What sensor is that ? which you were removing to clean with syringe and degreaser 😁

Where to find this sensor on the citroen c2 1.4i vtr manual petrol car and Also where is the temperature gauge for this model cause I see where the fault appears but not sure if that's the engine temperature or room temp

super vous avez trouver mon probleme merci beaucoup maintenant je cherche ou trouver cette pieces en neuve

Hi, petrol or diesel motor?

Well done!!!

Hi, would this solenoid be roughly in the same position for a 307 2.0l petrol? Thankyou.

Saludos! Esto servira a peugeot 307 sw 2.0 7 pasajeros gasolina modelo 2003?

hi i have antipollution fault have a peugeot 807 2006 diesel im wondering if u cud tell me were the vvt solenoid is

Thank you

Thanks man🎉

I tried this and it didn't help. I've understood there are 2 of these? This is hard one to crack since it seems there's so many reason it could be doing so

That looks like a variable valve timing solenoid, not a pollution sensor.... pollution sensors are based around the exhaust

Thank you I might try these method, I have been driving with my puegot 308"petrol 2010 it show same sign, took garage quoted me £200 said its oxygen sensor need to change, I might give a go never tried but looks easy steps, thank you, if it's worked I'll let you know,

I have 308 sw the fault pops up at least 2 times a year so this time it never reset itself so i did everything in the video only thing this time was engine was shaking bad - after doing it the light did go out and came baxk on but the car runs so smooth now

I’ve got a 207 and the antipolution lights comes on and my engine shakes and the fan turns on. The car doesn’t over heat tho I’m not sure what’s going on

Cheers man

hello , thank alot , do you know the fault code that it give .

Hi...thanks for the solution. However, I tried to locate this sensor on the 207 and somehow it is not the same as on this 308. Wish I knew how to locate this sensor on the 207.

would this be the same for a peugeot 3008 2010?

Citroen c5 2001 gasolin have the same?

What degreaser did you use?

How about 1.4 disel engine (Peugeot 207 09' )

Ja očistio senzor ali i dalje mi pokazuje grešku.

That is a VVT solenoid valve, not a sensor... 🤦‍♂

Managed to clean this part but fault still showing 😒

why do you keep calling the solenoid a sensor? 🤣

Today I must try on my car(Peugeot 207) ;)

That's not a sensor it's a solenoid

Kod mene ne radi..207 je smeće od auta😂

That will not work, and as anyone can see the valve is clean when removed. rubbish video

seriously needs to delete this vid or correct it

I have a better idea - just get yourself a decent car and save yourself a lot of time and trouble :)

But that afects the car by Any way if îs driven like that
