AIR FLOW METER Malfunction

Hello friends ...

2009 model 1.6 hdi car was serviced at 44 thousand km while the air flow meter was removed and installed. After the maintenance, the engine section was washed with diesel oil. There was no problem before I went to maintenance. A malfunction lamp came on 1 km after the maintenance was completed. We connected the vehicle to the computer and found that the air meter was defective.

My question is:

1) What happens when the air pressure meter is defective? By the way, my vehicle is now at 49 thousand km ...

In the official link of the track:

Check that the electrical socket is not fully seated. Maybe liquid may have entered the connector.

[QUOTE = ahmet_bjk] Hello friends ... While my 2009 model 1.6 hdi vehicle was being serviced at 44 thousand km, the air flow meter was also removed and installed. After the maintenance, the engine section was washed with diesel oil. There was no problem before I went to maintenance. A malfunction lamp came on 1 km after the maintenance was completed. We connected the vehicle to the computer and found that the air meter was defective. My question is: 1) What happens when the air pressure meter is defective? 2) Is it malfunctioned because it is disassembled and installed? thinks there is a shortage of air coming into it and first of all the vehicle falls out of traction, you can not get a performance as before on slopes, it may feel as if someone is holding it from behind (it is felt more on slopes). It has always been observed that it does not turn on the malfunction lamp. 2) I don't think it will break down by disassembling, it may be due to washing, There may be liquid contact as my Aykut teacher said. 3) If you clean it well and dry it (air can be retained), use it for some amount and try it again, if it fails again, you can go to the replacement, but when you talk to the master in the service, he said that it is not a piece that will easily break down, or even a defective part of the wire area in the part you showed in the picture. He said that they were clogged or dusty in the way and that they continued to work properly after they were cleaned well. Of course, there is no rule that everybody will do this, but it will not hurt without trying. My car has changed 90 thousand but my inexperience has seen the previous master has seen the fault, the flow meter in the system will change defective, neither another control nor cleaning made 190 lira.

I think you should check your socket first.

I somehow clean the metal area, but I don't know how to clean the socket.

flow meter measures the amount of air that enters the engine and & nbsp; opens and closes the egr valve according to these measures, if the flow meter measures wrong, egr will hurt more, it will press more exhaust gas to the engine.

I know that the flow meter should not be cleaned with diesel, it needs to be cleaned by spraying the sprays with volatile liquids such as gasoline thinner.

There is no problem with traction and fuel, only the fault lamp is on !!

it goes out soon :)

your friends are wrong. not only dropping the car out of the car .. the malfunction lamp burned in me, a month onoce flow meter malfunction appeared .. but there was no traction drop in my car and it was normal in the fuel. On the contrary, I'm doing too much pressure on me .. I changed the malfunction lamp does not light up.

Friends who understand electronics;

Should there be a link between parts 1 and 2 in the picture?

< p> When I took a measurement, I noticed that there is no connection, does the malfunction occur from here?

I cleaned this piece two days ago, I replaced it today but unfortunately the malfunction lamp is still on.

There is a chance that the light will go out after a while, but for now cleaning has not worked. (

teacher, these malfunction lights do not go out on each model, I suppose & nbsp; I also turned on the malfunction lamp from the brake sensor. I changed it did not go out by itself. We deleted the fault record with the computer connection and the fault lamp went out. As far as I understand, some of the failures are called encrypted failures and can be extinguished with a computer connection.

Today I connected the vehicle to the computer and deleted the fault, but it came out again instantly.

So the cleaning process failed ...

An auto electronicsian said that he can repair this piece and make it at least 50 lira. >

If it is possible to repair, I will investigate how healthy it is and try to find out what will be repaired. I have always said that if there is a possibility of repair, then there is a bit of a defeat ??
