    Icon6 Anti pollution fault

    G'day,
    it has finally happened. At 69,xxx kms, driving along yesterday, minding my own business, a bit of a bump and the dreaded message and dash light appeared. It run rough for about a km then smoothed out and ran ok. Started alright this morning, with the same message and light. I have a search back through the forums, but the only posting appeared to be about 8 years ago, and not really related. Any Ideas ?

    G'day,
    seemed to have fixed it. Disconnected the battery, reconnected a couple of minutes later, fault gone.
    Just like a Blackberry. Is there some similarity here, given the French connection with Canada?

    What car is it? Only clue I can find is your forum name of 206GTi, so let me assume, for the moment it is a 206GTi. Personally, never experienced 'pollution fault' message on a 206, but certainly have on 307 's and 407's, so here is my experience, for what it is worth.

    Could be faulty lambda sensor ( oxygen sensor in exhaust) but it could also be just a 'dirty' lambda sensor, caused by short stop start running or low grade fuel. So before replacing any parts just try this... Fill tank with 98 octane fuel (shell V Power or BP Ultimate. Then go for a nice long drive on an open road, for about 50k at 100kph... THEN... Whilst exhaust still nice and warm find a big hill and work the car hard on a hill climb.. That is using 3rd gear sit the car on 6000 RPM all the way up the hill.


    This should burn off any contamination on the lambda sensor.


    Other possible causes are, if above fails, a faulty lambda sensor OR a faulty monitor.


    Give it a try, see how it goes... Rod

    What you have done here is to ERASE the memory, but not corrected what caused the problem, so it may come back again, if so try my 'burn off' method.

    I am wondering if it had anything to do with our recent group "fording" adventure:

    Happy to plug it into Pug Planet for you.

    G'day,
    sounds good to me. The car is a 180.

    I filled up on Friday, the same servo I have been using for the past five years. However any excuse for a drive.

    G'day,
    that was fun. I went about 120 kms at 110 - 130 kph then up the Lapstone hill in 3rd and 2nd. No re-occurrence of the fault.

    AFAIK, it takes two (or maybe three) "good" starts for the fault to clear if the issue that first triggered it is no longer there. It just may be that the start after disconnecting the battery was the second "good" start.

    G'day,
    I'm always up for a nice quick drive. At the moment I am driving to work because of my knee, about 4.7 kms. After Wednesday, hopefully, I will be back on the bike.
    regards,
    Les W.

    I recently had this, and took it into a re-mapping specialist (no previous peugeot experience). He took one look and asked "does it have a fly by wire throttle?" which it does.

    Apparently it's not uncommon for the throttle body and pedal position to get unmatched if you have a sudden jolt on the pedal on/off. This then causes a fault in the ECU.

    I've had a similar issue 2-3 times, and thinking back it was when given a sudden throttle on/off.

    Another important starting procedure for a 206GTi 180 is on EVERY start-up, to turn key ON, but do NOT start-up yet... Instead wait for about 10 seconds, until some of the warning lights go off... tHEN start the engine. It will run much smoother and reduce the amount of unburnt fuel entering exhaust system. This in turn will reduce risk of lambda sensor contamination ( lambda fouling)

    G'day,
    I do that, every start, refer to previous posts on starting a 180, of which there are many. I usually wait about one minute, until all the lights turn off. I will fill with 98 on Friday and go for a run early on Saturday, when it is nice and cool. Anyone for breakfast ?
    regards,
