Lambda (oxygen) sensor

Hello friends. I have a 206 xt 2004 model car
I've written before. The engine diognastic lamp burned, the injection nozzles changed, the spark plugs changed, we extinguished the lamp. We went to the inspection, the vehicle did not go through emissions. I changed the catalyst, got the original coat. Again, the last right remained, meanwhile, the engine malfunction lamp came on again. Now my question is. Does the lambda sensor cause the engine lamp to turn on. I almost never have to replace the engine. Measurement values are too high.
Thanks for your interest poyraz61 2016-05-11 10:03:51

There is another name (oxygen sensor) that you call lambda sensor, while some vehicles have 1, while others have 2. Yes, this sensor lights up the engine lamp, so it causes emission values to be high due to the vehicle not being able to burn fuel completely. (rich-poor mix, etc.) As far as I understand, you have made exhaust emission at the tv station, I think it is a little troublesome there. Also, if your vehicle has LPG, you can make high differences between emission values taken with LPG and emission values taken in petrol.

No, teacher. No LPG in my vehicle. Yes, I also had a tuvet, but it gave me 900 lira to the catalytic convector, which freaked out my life, and again, at the same values. We made bidet tanidikya. He picked us up. Replace the sensor and let the emission measure be done outside the bidet. My goal is not only to pass the exam, but also from the examination. I am going to use this vehicle, so the engine lamp will bother you

Then the sensor is defective, teacher, because the engine adjusts the mixture of fuel and air to these sensors. Why did the master change the catalyst strangely in the master? Replace the sensor first? Also check my air filter hoses. Check if the air filter is fully seated. Even too much air inlet to the right may cause a rich poor mixture. When the pc was connected, what error was the vehicle giving?

My teacher gives a rich mixture error.

Okay, thank you very much, there seems to be a cost of 300 lira.
