Citroen C4 Picasso - P2201 & P2204 Nox Sensor; Faulty Measurement of the Nox Content 😌

[@kennedysgarage3281]

Good video Sandy, quite a few handy tips. I haven’t ever interchanged just the tip of the Nox sensor. I actually don’t like cutting and joining so many wires, even on lambda sensors. Cheers mate 👍

Good video Sandy, you show nicely how ineffective the NOX system is on short journey diesel's because of the warm up time required. In my experience, they mostly fail due to water entry onto the pcb in the module. It would be better if they mounted the box inside and passed the cable through the floor.

Some extremely useful information there thank you Sandy.

Обычно на форсунке адблю образуются кристаллы что дает недостаточное распыление . Снимаете аккумулятор ( клемы) , демонтируете форсунку и промываете в теплой воде . Ставите все на место и стираете ошибки . Адблю лучше использовать от WV , работает более корректно.

I had that same dash message on my 2014 grand picasso and all it was was that the Adblue needed to be topped up. This happened many times as long as I owned the car. Everytime I would get the same same errors on the dash, top up by more than 5 litres, and then the messages would clear without me doing anything.
