Air Flow Meter/Sensor: Service and Repair

Mass Air Flow Sensor

- Disconnect electrical harness connector - 3 - at mass air flow sensor (G70).





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

Installing

For problem-free operation of the mass airflow sensor (G70) it is very important to observe the following notes and procedures.

Mass Airflow Sensor (G70) - 1 - seal - 2 - Installed Position





The smooth side of the seal must contact the mass airflow sensor (see the magnifying glass).

• If the air filter is very dirty or soaked, dirt particles or moisture may have contaminated the mass airflow 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 lubricant (silicone-free) for installing the intake hose.

• Secure all hose connections using hose clamps of series-production status. Refer to the electronic parts catalog ETKA

- Replace the seal for the mass airflow sensor. Make sure it is installed correctly otherwise the air could get in.

- 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).
