Upstream sensor

Post by DMC23 »

Does anyone know if a 2016 308 1.6 blue 120 has an upstream NOx sensor (before the DPF) or if the downstream sensor (after the DPF) is all that it has?

My Autel live data always shows a zero PPM reading for upstream but I get readings for downstream

I'm thinking it doesn't have an upstream sensor, can anyone confirm that?

Pretty sure it's downstream only. If it's working don't mess with it!!
