Some 2018-2019 Ford Mustang vehicles built on or before Oct. 17, 2018, equipped with a 2.3L EcoBoost engine and operating in altitudes 3,500 feet above sea level and higher may exhibit an illuminated MIL, with P0068 stored in the PCM, requiring PCM reprogramming.
Using the appropriate scan tool, retrieve DTCs. If P0068 is stored, reprogram the PCM using the latest software version.
