Some 2013 Ford Mustangs built on or before 11/30/2012 and equipped with a 5.0L engine and manual transmission may exhibit a check engine light accompanied by any combination of DTCs P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307 and/or P0308 stored in continuous memory only. Additionally, there will be no apparent drivability symptoms present and no other DTCs.
This bulletin applies to 2005-2013 Chevy Corvettes (including Z08). The check engine light may be on, with DTC P0171 and/or P0174 set in history or current. If air flow to the air intake/air cleaner assembly is disturbed, these DTCs may be induced.
This bulletin applies to 2012-2017 Buick Regal models. Some customers may comment that the check engine light is illuminated. In “rare” cases, they may also comment that there is no PRNDL display. When checking for DTCs, technicians may find P182E set as active or history in the transmission control module (TCM).
