Air Flow Meter/Sensor: Service and Repair

Mass Airflow Sensor (G70)

Removing

- Disconnect the connector - 1 - from the Mass Airflow (MAF) sensor.






- Remove both bolts from the MAF sensor and carefully remove the MAF sensor from the air filter housing guide.

Installing

For problem-free operation of the MAF sensor it is very important to observe the following notes and procedures.

• 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 hose.

• Secure all hose connections using hose clamps appropriate for the model type: Parts Catalog.

- Check the MAF sensor and intake 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).
