Air Flow Meter/Sensor: Service and Repair

Mass Airflow Sensor (G70)

- Disconnect the electrical harness connector - 1 - from 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 MAF values. This results in a reduction of power, since a lower injection quantity is calculated.

• Always use an original equipment air filter element.

• Use a lubricant (silicone-free) for installing the intake hose.

• Secure all hose connections using hose clamps appropriate for the model type. Refer to the 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 upper air filter housing and lower air filter housing of salt residue, dirt and leaves. Wash or vacuum if necessary. Air filter, removing and installing => [ Air Filter Element ] Service and Repair.
