Hello I'm Chris a Ford Employee and Certified Engine/Transmission Specialist.
Thanks for asking your question. I am eager to get your vehicle back up and running correct. Be aware it is difficult to fix concerns associated with noises and smells over the net, but I will do my best. Diagrams are often copied from other websites. I am here to help you out for a small fee far less than a dealership and easier on the wallet, so if this information is of aid PLEASE PRESS ACCEPT and help me out financially by paying the small fee (which you selected). Please reply if further discussion is needed.
All of these are air bag faults and have nothing to do with the check engine light being on
