Mickey603 Posted May 27, 2016 Share Posted May 27, 2016 Have a regen issue with my Mack. 2011 Mack LEU613 - MP7 SPN 3491: Aftertreatment DPF Atomization Air Actuator FMI 12 / Faulty Device or Component. Mid128 - Engine ECU Psid59 - Aftertreatment atomization air solenoid FMI 12 - Faulty Device or Component I have a few units in the shop. Does anyone have a diagram of the components? I fixed one before with just swapping out the solenoid. Can just the solenoid be purchased?
