SUBJECT:
FUEL TANK AND/OR PCSV CHECK VALVE
INSPECTION/REPLACEMENT + ECU SW UPGRADE (SC288)
This bulletin provides information to inspect the fuel evaporative system and, if necessary, replace the fuel
tank and/or the Purge Control Solenoid Valve (PCSV) check valve on certain 2021-2024MY K5 (DL3a) vehicles
equipped with a Gamma II 1.6L T-GDI engine, produced from March 27, 2020 through October 17, 2023. This
bulletin also provides information to upgrade the ECU software logic. The subject vehicles may experience
fuel tank swelling due to an issue with the PCSV check valve, which results in pressurized air to flow into the
fuel tank. This may cause the Check Engine Light to illuminate, and in some cases, the engine to run rough,
and/or an inability to refuel. These conditions may cause the vehicle to release air pollutant which exceed
Federal and California standards.
Please note the replacement part(s) are not yet available. As soon as replacement part(s) become available,
this Technical Service Bulletin (TSB) will be updated with the proper inspection/replacement procedure,
replacement part(s) and labor op code information. Before conducting the procedure, verify that the vehicle
is included in the list of affected VINs.
