The hose is for heated air to the intake, 3 things could happen, in winter the intake throttle valve could freeze up, 2nd you can fail your visiual smog test, and 3 poor fuel economy. This hose goes to the exhaust mainfold sheet metal heat stove, it is cheap to buy, replact it.

Where is the mass airflow sensor on opel zafira 2.2

On the 2.2 zafira, z22se engine. There is no MAF sensor. Which is why you can not find it.
Instead it uses a combination of the IAT (Intake Air Temp) and the MAP (Manifold Air Pressure) sensors.The IAT is the small plastic sensor on the side of the intake duct.The MAP sensor is just after the throttle body. You need to take the whole throttle body off to get at it.

Where is the IAT sensor

The Intake Air Temperature (IAT) sensor is the same as the Manifold Air Temperature (MAT) sensor on earlier models. IAT is located in or near the air intake duct (click image for zoom).


Fig.: On 1996-98 vehicles, the IAT sensor is mounted in the rear air intake duct

Hope this helps (remember to rate this free answer).

Where is the Mass Air Flow Sensor located in the vehicle?

MAF sensor is in the intake air duct between the air filter and the throttle body mounted on the intake manifold. MAF sensors are mounted directly to the throttle body.

I have a 2004 chevy aveo and there was a split in the air intake hose that i was unaware of until the engine started to stall. I sprayed carb\manifold cleaner in the valve and replaced the hose and now it...

email me. Check and make sure all vaccum hoses are not cracked. Basically anything connected to you throttle body, or intake that is made of rubber replace it. there is a small crack. happened to me this week. small air leak makes a difference. also if you can replace the intake with a cold air intake. Runs way better.

    Sounds like intake air system, look for cracks in hoses (possible intake manifold gasket) all vacuum hoses and connections. Make sure TPS and all filters are clean. Sounds like a lean mixture/flooding issue. Common problems with FWD is the Air Intake Hose, lots of flexing. Cracks form on the bottom and debris comes off inside over time(thus fouling the TPS downstream). Remove inspect carefully, If it is hooped you can fab one up yourself with PVC and some clamps and Aluminium Dryer Ducting. With the proper alignment and bigger airways you will boost your performance. The TPS can be cleaned with Carb Cleaner, replace the air filter and then test with a Vacuum Pressure Gauge install in line, directly off a Intake Manifold Vacuum port.

    Try that and get back to me? I'll be around...
