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.
