DTC P0420 Catalyst Malfunction

My car 2013 model 1.0 gasoline 208. The orange engine lamp has been on for some time now and has been causing Catalyst Malfunction with code P0420. They said that the catalytic converter needs to be cleaned in the service, but as far as I investigate it is said that this is not a good solution.

What would you suggest, where is the best solution in Istanbul? What method can I solve?

And what problems can I face if this problem is not fixed?

Thanks.

Arrangement: It was also said that a BSI Adaptation should be done from the service to the vehicle. Do you think this could be a solution?

Probably the problem is when my teacher in fuel quality uses it without a cycle, such problems can occur. Cleaning usually solves the problem and you do not experience the same trouble for long periods of time. My recommendation is to replace the spark plugs and use floor cleaning additives and use them and use the vehicle in a calm place such as the ring road. BSI adaptation is actually a software update. If you have the software update first and then use the wür or link I have given, the problem will probably be solved.

Thank you so much teacher

I also have 208 with 1.2 vti lpg. For about 1.5 years, the catalyst and rich mixture had been malfunctioning, and it was emitting heavy black smoke while in gasoline. They said that wherever I go, the catalyst will change. The last time I went to a master I found on the internet. He said the problem might be from the map sensor or the oxygen sensor. We disassembled the oxygen sensor and looked inside the catalyst, it looked clean. We asked the sensor prices, as you know it is quite expensive and it was not in the hands of the parts. Oxygen sensor is black. The master cleaned those two sensors and connected them to the computer and updated something, and the vehicle idle until the fan was running, connected to the computer. And my problem has been solved, now I have passed 500 km and the sound of the vehicle has come to its own. I solved the problem very cheaply in this way, and now I get on gasoline, it is almost burning as much as diesel.

I have had the same problem for 3 months. I am deleting the p0420 code 200

300 km later. LPG vehicle, but. I have been using gas

for 2 years. Could you guide me what kind of treatment they applied.

If I was close, I stretched to the old city.

Thanks in advance. Thank you

İhtiyacınız olan 1Mohm değerinde 1 adet direnç ve 1uF kondansatör.

Öncelikle katalizör sonrası yani 2. Oksijen sensörünü soketinden çıkarıp 22 numara anahtar ile söküyoruz. Dışındaki korumayı sıyırıp kabloları ortaya çıkartıyoruz. 4 adet kablo var beyaz olanlar sensörün ısıtması için o kablolarla işimiz yok. Bizim işimiz siyah ve gri kablo ile siyah olan sinyal gri olan şase kablosu oluyor. Siyah kabloyu sokete yakın bir yerden kesiyoruz ve 1Mohm değerindeki direnci kestiğimiz yere lehimliyoruz. Daha sonra kondansatörün + ucunu direncin sokete giden kısmına lehimliyoruz. Ve kondansatörün - ucunu ise gri kabloyu kesmeden dışını sıyırın ve sıyırdığınız yere lehimleyin. İşlem tamamen bu kadar kolay. Araç ister lpg li olsun ister sırf benzinli olsun kesinlikle arıza ışığı yakmayı sonlandırıyor ve ikinci oksijen sensörünün voltajını 0.45v olarak sabit tutarak düzene sokuyor. Devreyi fotoğraf olarak da paylaşacağım. Fotoğrafta renkler farklı mavi olan bizim araçlarda siyah kablo beyaz olan bizim araçlardaki gri kablo olacak.

Herkese şimdiden kolay gelsin.
