Air Flow Meter/Sensor: Service and Repair

Mass Air Flow Sensor

- Disconnect electrical connector - 3 - on Mass Air Flow (MAF) Sensor (G70).





- Remove both bolts from the Mass Air Flow (MAF) Sensor (G70) and carefully remove the Mass Air Flow (MAF) Sensor (G70) from the air filter housing guide.

Installing

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

• If the air filter element is very dirty or soaked, dirt particles or moisture may have contaminated the Mass Air Flow (MAF) Sensor (G70) and may be causing false mass air flow 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.

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

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