Peugeot 206+ Oxygen (Lambda) sensors replacement 

Another thing always clean off surfaces before replacing the part for a better flush fit

Ok I just saw it on the video, it is 22mm. Hard to see it watching the video via Smartphone 😆.

Something like that : www.amazon.co.uk/Baceyong-Oxygen-Sensor-Installation-CUT-OUT/dp/B0978RR5QW/ref=mp_s_a_1_11?keywords=lambda+sensor+socket&qid=1661179807&sr=8-11

Do you have a check engine light on dashboard ? Can you read obd trouble code and see if there is an error code ?

Hello ! Happy you like the video. Can you please re phrase question I’ll be happy to help

@@orenweinstock6867so this statement is true then ? : " White and white are heater wires, it doesn't matter whether hot or ground goes into which white wire. "

Correct

I also used generic Bosch sensors on another car. Works fine

No

Eventually I was needed to replace with Peugeot genuine ones, those didn’t work well

@@orenweinstock6867 what was the problem? Did it report the antipollution faulty code again?

@@VukLazarevic - Exactly, emission code came up again ! non-original parts didn't work for me in this case

@@orenweinstock6867 oh god damn it I also bought a third party lambda sensor and I never understood why the hell I get the code every now and then, it drives me nuts. Should have bought the original part but it cost a lot more ffs :/

@@VukLazarevic check another thing that raised emission trouble coded as well >> I had a leak of exhaust gasses in the middle flange below the vehicle (they found it in the MOT). Once solved and new original lambda installed car run perfectly and fuel consumption improved

Hi 👋 not the same sensors

Yes
