  Engine PNs: MY 24-26 WD/DT (5.7L) Code P00B is being misdiagnosed and incorrect parts are being installed causing over repair. Refer to SOL S2609000006 The IAFM Foam Engine Valley Cover (PN 53013735AB) does not provide sufficient clearance for proper routing of the MDS solenoid jumper harness (PN 05148163AE). As a result, the harness may become compressed by the foam cover. To prevent unnecessary part replacement, the MDS solenoid jumper harness (PN 05148163AE) should be inspected for damage or pinch conditions prior to replacing the following part numbers: Engine PNs: 68409343AA 68409357AA 68450915AA OCV PNs: 53022338AB Phaser PNs: 53022298AA 53022298AB
