and the output temperature sensor should read ambient exhaust temperature or higher than exhaust temperature when regenerating

Ok so with the flex pipe crack will that cause a no reading on the exhaust temperature sensors? I did take a look at harness it’s all connected the only thing I noticed is that whenever the last dpf filter cleaning was done they did a terrible job with routing the harness they just let them sit on top of the filter . I could see how the heat was already burning on the aluminum protector before the cables. I don’t think that it burned the cables if not it will show up in insite software. Because exhaust temperature sensors read zero is what I don’t understand.
