In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 24% of dealership population. This is an initial order recommendation only, and the ultimate responsibility for ordering the total number of parts needed to satisfy the program lies with the dealer.
ACTION REQUIRED
Update the NOx sensor heat shield to the 545-8560 and 545-8561 Shields to protect the NOx sensor from radiant heat. It is important that no exhaust heat wrap is placed over the shield, to promote airflow around the NOx sensor. Replace the harness p-clip bracket to reduce the chance of sensor harness wear. Replace the NOx Sensor only if it has already failed.
