Hello All,
This is the first time I post something here. I used to be a regular member at Trailvoy forum. I bought a used Yukon XL 2007 SLE, I think, I hooked up my Actron scanner and found that two readings don't change no matter how I accelerated the engine; they belong to Oxygen sensors. I attached a snapshot of the reading and marked the constant readings for you experts to decide whether it is normal or not.
