How long can I drive with only a 4364 active?
Well with only the 4364 active you should have at least 4 hours of drive time left. You can try to regen it, the only problem with that is if it fails then that is one hour gone off of the operating time. Ok but if I go ahead to change the nox sensor will it fix everything?
