Hi all,

Thankyou ahead of time for your help. I have a 2020 ram 1500 ecodiesel and looking to clean my oxygen sensor.

I was wondering if any of have done the above and if so, specifically which one should I clean and with what solution?

I have over 275k and want to prolong it without deleting the egr.

All help is much appreciated.
 
Yes.. theres 2 that i can see, up and downstream but one you should clean and the other you dont really need to
 
looks like the Oxygen sensor is on the elbow between the Turbo and the DOC/DPF.. The top one is the O2 and the bottom one must be the pre-DPF NO2?
