Air Flow Meter/Sensor: Service and Repair

Mass Air Flow Sensor

Removing

- Disconnect connector from Mass Air Flow (MAF) sensor (G70) - 2 -.

- Open hose clamp - 3 - and clips of Mass Air Flow (MAF) sensor (G70) and remove Mass Air Flow (MAF) sensor (G70).





Installing

For problem-free operation of 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 MAF sensor and intake hose (intake air side) for salt residue, dirt, and leaves.

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

- If air filter element was removed, blow out water in lower part of air filter housing with compressed air.

Further installation is in reverse order of removal.
