- Summary
- Some 2020-2022 Mustang GT500 vehicles may exhibit a lack of power and/or an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P1228. This may be due to the one-way clutch on the supercharger drive assembly. With the supercharger belt removed, a failed one-way clutch within the pulley rotates freely in both directions. The supercharger drive assembly KR3Z-6J022-B is now available as a lower level service part, separate from the supercharger assembly. Refer to the parts catalog and Workshop Manual (WSM), Section 303-12 for installation.
