Pressure protection valve - boondocker - 03-09-2021
Has anyone had trouble with this in the secondary air tank. It feeds my air purge and I believe my fan hub supply. Below freezing my fan stays engaged and I get code 3490 for the purge air actuator every time the truck does a passive regen. Has anyone tried cleaning this valve out as I believe it may be sludged up. Thanks Steve

what year, make, model truck, engine, etc.. some history would likely help.
