OEM PCV Hose for 2001-2004 Nissan Pathfinder models.

The PCV (Positive Crankcase Ventilation) hose is a component of the vehicle's emission control system. It carries crankcase gases from the engine's crankcase back into the intake manifold, where they can be burned in the combustion process. Over time, the PCV hose can become worn, cracked, or damaged, which can lead to vacuum leaks and other engine problems.

Here are some signs that the PCV hose may need to be replaced:

• Visible damage: Inspect the PCV hose for signs of wear, cracks, or leaks. If you notice any visible damage, it is a good indication that the hose needs to be replaced.
• Vacuum leaks: A damaged or deteriorated PCV hose can develop leaks, leading to vacuum leaks in the engine. Vacuum leaks can cause a variety of symptoms, including rough idling, poor fuel economy, and reduced engine performance.
• Check engine light: A malfunctioning PCV hose can trigger the vehicle's check engine light. If the light is illuminated, it is recommended to have the vehicle diagnosed by a mechanic to determine the cause, which may include a faulty PCV hose.
• Excessive oil consumption: A failing PCV hose can disrupt the proper flow of crankcase gases, which can result in increased oil consumption. If you notice that your vehicle is consuming more oil than usual, it could be a sign of a faulty PCV hose.

Additionally, if the PCV hose is over a certain age or mileage (refer to the vehicle manufacturer's recommendations), it is a good idea to proactively replace it to avoid potential problems.
