How to Clear Check Engine Light on Toyota Aygo/Citroen C1/Peugeot 107 

What ??? No techno music soundtrack? No hillbilly American narration? Ahhhhh! A breath of fresh air. Thank you.

I came across this inadvertently. My C1 has this problem so can't thank you enough for putting this video up on RU-vid.

Just done this and it fixed the issue! Thank you!!

An excellent, concise tutorial-thank you.

Cheers mate that will save me spending money on a mechanic 👍👍

Cracking, helpful video thanks

you are a genius thanks 👍

Would have been easier to read the DTC first, just to confirm that the O2 sensor was the issue, before going through all that! Easy fix though and as you say, nice and easy to work on.

Just obtained a Toyota Aygo 2009 model so Thank you so much for this ingenius tip. However, I NEED the the make and model of your wrist watch…!!! Thanking you in advance. Best regards from Denmark :-)

Thanks for sharing.

Well I can honestly say I've never known a lamda sensor to undo with an open end spanner

Thank you

If I well remember, even without erasing the DTC, after 5 times of "good working" - turn on the car, have some minutes of good working, and turn the engine off, with key removal, waiting some minutes, the dtc will be clear automatically by the system, having the "memorized" status and not active status. The noise of something shaking after accelerate the engine, when it starts to reduce the revolutions, probably are your radiator electric motor plastic support shaking at the radiator base side - plastic connection at a plastic housing, near the floor, maybe at the left car side. you can ask to someone accel the car and you can press with your hand the plastic support to be able to find where it's shaking, having attention to the possibility of radiator´s electric motor activate, reducing the possibilities of injury yourself. If this is the problem, you can use some kind of rubber to make it like a dumper ou shock absorver.

Brilliant, like I have a diagnostic tool in my back pocket@!!

Thenks a lot 😊

1 KRFE engine same in Toyota Passo. Quickfix. Keep your tank at least half full if you don't want to get stranded with a failed fuel pump.

thanks..

How to disconnect the the cable from its frame fixture on the left of the sensor, about 9 inches from the sensor. It has a rubber seating - can it just be pulled away as you seem to have done? Otherwise it is difficult to pull (slide) out the cable - is that connector just a push fit or is it clipped in somehow? Please advise - thanks.

I got the p0420 fault code. I will clean the O2 sensor tomorrow. Did you replace the catalytic converter shortly after? Or was it just a dirty O2 sensor. The catalytic converter are really expensive here....

Thank you! I'm gonna try this. I've got the same error code : P0420

I will clean the O2 sensor tomorrow in some petrol for my 107, but I don't have an OBD2 scanner. Will this be a problem?? Is erasing the fault required? Thanks

Also check map sensor as this can cause this fault.remove throttle body(it's easy) give that a clean with brake cleaner and behind that is map sensor use electrical cleaner or specific map cleaner.twenty min job and I'm a complete novice.guides on other channels .

Hey could you do a video on fixing the flashing airbag light :)

how do i fix vsc light on my peogeot 107 ???

Before shooting the messenger I would check you don't have any manifold or catalytic converter leaks upstream from the sensor. These cars are notorious for the welds rusting through or the cat parting with the manifold. Also, getting an old O2 sensor out can be a bitch you may need a torch or you may well strip the threads.

Great tutorial , but you really need to fill up your petrol tank ! ! !

cool thanks . your out of petrol though :-)

Can I clean this with electrical cleaner instead of petrol?

Hi any body know how ro fix power steering proplem in Peugeot 107 2008 please

Or ignition on pump exilarator 6 times found this trying reset a b s.

Do you have to use petrol to clean it?

I've got the same error code : P0420 I change the O2 Sensor bud nothing . :(

Is this the same for the newer C1?

Hello Dear, Can this sensor failure cause problem while driving? 1-Car vibration, especially when its cold engine in the morning? 2-RPM indicator going to 3000 4000 rpm without pressing throtle? thx

hi does anyone know how to get rid of the airbag light flashing??

Great video thanks. Does anyone know how to clear a fault code without a scanner?

Doesn't the 1L C1 have 2 exhaust O2 sensors, pre- and post-catalytic converter?

After i do all of this in a peugeot 107 in 3 days the problem was there again. Problem is catalityc converter not o2 sensor

If you want to check the condition of both pre and post-cat sensors, before messing with probing, removals, I propose you check my recording done here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-SfcDyKFovpc.html

Please il have problèmes m'y car is not stret and the code p0141 bank 1 sensor 2 ???

Please i have problèmes my car is not stert and the code B2799

it will turn on again in a few miles...its a chronic problem... the better way is remove the dtc p0420 from the ecu permanently i made it and never turn on again.

Low fuel bud, mrs been driving it?

Missleading ! That sensor looks brandnew.... as old ones can be a pig to get loose and require a lot of wd40.....and sheer effort to loosen them

Échale bencina po wnnn xdd
