Air Flow Meter/Sensor: Service and Repair

Mass Airflow Sensor (G70)

Removing

- Disconnect the connector - 2 - from the Mass Airflow (MAF) sensor (G70).






- Open the hose clamp - 3 - on air duct hose to turbocharger and pull it off at MAF sensor.

- Remove both bolts from MAF sensor.

- Carefully pull the MAF sensor out of the guide from air filter housing.

Installing

Following the information and procedures exactly will assure the MAF sensor works correctly.

• If the air filter is very dirty or soaked, dirt particles or moisture may have contaminated the MAF sensor and may be causing false mass airflow values. This results in a reduction of power, since a lower injection quantity is calculated.

• Always use an original air filter.

• Use a silicone-free lubricant for installing the air guide hoses.

• Secure all hose connections with hose clamps of the same type as those equipped by the factory. Refer to the Parts Catalog.

- Check MAF sensor and air guide hose (intake air side) for salt residue, dirt and leaves.

- Check the intake channels up to the air filter for dirt. If any contaminants are discovered, clean the air filter housing (upper and lower sections) of salt residue, dirt and leaves (if necessary, clean by washing or vacuuming).
