If you own one of the V6 Mustangs produced between the dates of October 12th, 2011 and September 26th, 2012, letters are being sent to dealers and owners alike regarding an emissions glitch. The Ford dealers are becoming aware of the issue to get the problem resolved for the vehicles coming in for service. Vehicle owners should receive letters by February 28th. Just to be clear, this is just for the 2013 V6 Ford Mustangs built between the dates above.

“In all of the affected vehicles, the Electronic Throttle Control (ETC) Failure Mode and Effects Management (FMEM) strategy, when active, correctly sets a Diagnostic Trouble Code (DTC) and illuminates the “wrench” light for the customer, but prevents illumination of the “Check Engine” light on the next driving cycle as required by On-Board Diagnostic (OBD-II) regulations.”

Basically, there’s a glitch in your system causing the “Check Engine” light not to come on after the next required On-Board Diagostic (OBD-II) driving cycle caused by the Electronic Throttle Control. No worries, if you’re not sure what all of that means, it’s a pretty easy fix according to the techs, just a reprogram of the PCM, or Powertrain Control Module, and about fifteen minutes of work. For service advisers, this is for the latest level PCM with IDS release 81.03 or higher.

Also, the repair is free of charge from your local Ford dealership so just stop in for a quick fix, or just get it done while you get your vehicle serviced. It’s no big deal, just a couple minutes and you’re on your way.
