Hey everyone My name is Wael and Im from Sweden. our mechanics suck and they charge so much money and fail to repair. let me tell you my long short story. I purchased a car last summer called KIA Venga. I used the car to commute and its been in total like 16000kms without any issue. I sent the car for inspection few weeks ago and they told me the check engine light is not working. I dug into this and found out the bulb was removed by the previous buyer, I put a new bulb on and then check engine light is on ever since. obd2 says MAF sensor with code P0101 so I cleaned the sensor and erased the code but it came back. I put a new MAF sensor on and erased the code but it came back. one mechanic worked on the car for about 2 days and he suspected that the new sensor is maybe not as good. he said no vacuum leaks and wires are fine but he can’t find any issue. the car is running really fine without any problems. I drove 700kms up north in the winter none stop and the car performance was as good as any used car. what else can I do to find out the problem? I mean since the performance is very ok and with the new man sensor on what else could be the problem? regards ---

What is the year of this vehicule because it might be under warranty. ---

Maybe the previous owner removed that bulb because he already knew that it was not causing any drivelability issues. Some vehicules perform better with the OEM part compared to an aftermarket part…I know my toyota does. I suggest you get the OEM if its available. ---

No its an aftermarket part. I thought why invest in an OEM if Im not sure if its the problem or not. Do you suspect anything else like exhaust or whichever parts related. Thanks anyway ---

Or maybe its even worse than just the MAF sensor🥲 ---

You say the car runs fine… a blocked exhaust… another possible cause of a P0101, would not run fine. Other causes, wireing and dirty maf have been addressed. That leaves me with a sub-standard maf as a possible issue. Kias may be extra sensitive to that. ---

I have met 2 mechanics and the dealership so total 3. First 2 couldnt identify the problem and the dealer wanted more time which means shit loads of money. In my profession I solve problems related to my work and i like the challenges i meet in my work. Those mechanics dont like challenges, all they do is changing filters and oils. Im sure there are some good ones but honestly i havent met one yet. I spent 600 euros already and my car isnt fixed yet. Now please disregard this matter and lets stick to what we know to solve this issue. Thank you ---

With this specific problem, and others that are like it, I Google something like Kia forum P0101. I tried that and got a lot of links, but this was the first. [https://www.kia-forums.com/threads/keep-getting-p0101.66730/](https://www.kia-forums.com/threads/keep-getting-p0101.66730/) ---
