Exellent video my friend, kee it up ,I've encountered this problem on many where a cracked decomposition tube was the root of ehe problem, best luck to you all.
doubt that fixed it. its rare the sensor is actually bad if there is no crystallization or plugged dosser and def filters are clean its probably reading too much nox and the problem is somewhere else iv seen tecks replace these sensors multiple times in the same truck waste money
Funny when we see nox drift it’s usually a bad nox sensor. Plus on those trucks all the salt and rain a debris collects on top of that sensor and corrodes it. So yah most need them changed anyways
