Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, stethoscope, flashlight.
Ensure the vehicle is parked on a flat surface and the engine is off. Allow the engine to cool if it has been running.

2. Inspect Air Intake System

Remove the air filter assembly:
- Loosen the clamps securing the air intake duct.
- Disconnect any sensors attached to the duct.
Check the air filter for dirt or damage, and replace if necessary.
Inspect the air intake duct and throttle body for cracks or loose connections. Replace any damaged components.

3. Check Seals and Weather Stripping

Inspect the door and window seals:
- Open all doors and visually inspect the rubber seals for cracks or gaps.
- Run your hand along the seals to feel for air movement.
Replace any damaged seals to ensure a tight fit, which can prevent whistling noises.

4. Test Drive

Reassemble any components removed during inspection.
Start the engine and take the vehicle for a test drive at varying speeds to confirm the noise has been resolved.
