2003-2007 Nissan Murano Engine Air Intake Duct Service Bulletin

Nissan is conducting a voluntary safety recall on model year 2003 – 2007 Murano vehicles. Under certain conditions, the intake duct, which is connected to the intermediate resonator in the air intake system of the engine, may separate from the resonator with engine movement. This could cause minor idle fluctuation or poor acceleration. If this occurs, and the vehicle continues to be driven without being serviced, the engine may stall while driving. To remedy this potential condition, Nissan is conducting this voluntary safety recall campaign to replace the air intake duct with an updated part and the air duct clamps with new clamps at no charge for parts or labor.
Service Procedure:
1. Disconnect the Positive Crankcase Ventilation (PCV) hose from resonator 1.
2. Loosen the clamps shown in Figure 1 (clamps at both ends of the air duct assembly).
3. Remove the air duct assembly from the vehicle and set it on a clean working surface.
4. After removing the air duct assembly, cover the openings to the electronic control throttle and airflow meter with clean cloth / rags.
CAUTION: • Make sure to cover the openings to the electronic control throttle and airflow meter.
• Covering the openings will prevent debris entry.
5. Loosen both wire clamps shown in Figure 2 (clamps on both sides of resonator 1).
6. Replace the wire clamp on air duct B.
a. Pull air duct B away from resonator 1 just enough to remove the old wire clamp and install a new one.
• Bend the old wire clamp so it cannot be reused.
b. Reconnect air duct B to resonator 1.
CAUTION: Before installing air duct B, use a clean cloth / rag to wipe away any debris from the duct and resonator.
