Solution

1. Preparation

Gather tools and materials:
- Torx screwdrivers (T20 and T30)
- Mass airflow sensor cleaner (specifically designed for this purpose)
- Clean lint-free cloths
- Safety goggles and gloves
Ensure the vehicle is parked on a level surface with the engine turned off and cool.

2. Remove the MAF Sensor

Step 1: Disconnect the battery.
- Use a wrench to remove the negative terminal.
Step 2: Locate the MAF sensor.
- It is typically found between the air filter and the throttle body.
Step 3: Disconnect the electrical connector.
- Press the locking tab and gently pull the connector away from the sensor.
Step 4: Unscrew the MAF sensor.
- Use a Torx screwdriver to remove the screws securing the sensor to the air intake duct.

3. Clean the MAF Sensor

Step 1: Spray the MAF sensor cleaner onto the sensor.
- Hold the sensor upright and spray the cleaner onto the wire elements inside the sensor. Avoid touching the wires.
Step 2: Allow the cleaner to dry completely.
- Wait for at least 10 minutes to ensure all cleaner has evaporated.

4. Reinstall the MAF Sensor

Step 1: Position the MAF sensor back into the air intake duct.
- Align and secure it with the screws removed earlier.
Step 2: Reconnect the electrical connector.
- Ensure it clicks into place and is secure.
Step 3: Reconnect the battery.
- Attach the negative terminal back to the battery.
