TSB 22-2185

Some 2021-2022 Mustang vehicles built on or before 21-Apr-2022 and equipped with a 2.3L EcoBoost engine may exhibit an illuminated malfunction indicator lamp (MIL) and diagnostic trouble codes (DTC) P0300 and/or P0316 in the powertrain control module (PCM). This may be due to various strategies within the PCM software. To correct the condition, follow the Service Procedure to reprogram the PCM.
