AIR CLEANER \- NONE Instruction to Dealers while ordering the PN\# 68137142AD. 1. If the Air Cleaner Assembly is functional and only the MAF Sensor has failed, the dealer should order and replace only the MAF Sensor\(68002441AC\). 2. If the Air Cleaner Assembly has failed and the MAF Sensor remains functional, the dealer should order the new Air Cleaner Assembly PN\(68137142AD\) and reuse the existing MAF Sensor\(68002441AC\) from the failed assembly. 3. If both the Air Cleaner Assembly and the MAF Sensor have failed, the dealer should order both the New Air Cleaner Assembly\(68137142AD\) and the MAF Sensor\(68002441AC\) as separate service parts. - [9100898](/bulletins/11037347.md), 2026-09-17, Service bulletin: ENGINE. 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 - [9100363 Rev 3](/bulletins/11036762.md), 2026-09-03, Service bulletin: ENGINE.
