Question: do the "diagnostic trouble codes" listed in this TSB cause the "check engine" light to come on?
I ask because when I requested that the service rep have the mechanics check to see if this applies to my Focus, built 2/6/12, she said, "these would cause the check engine light to come on." And without that, she wouldn't add it to the work order.
I'm guessing that she was wrong, and that I will have to go over her head to get someone to at least check to see if the TSB applies. Am I right?
