P0101fb ошибка мерседес glk220cdi

Пробег: 76 500 км

Вообщем приехал авто с жалобами — неедет. До меня делали диагностику и приговорили ДМРВ, купили,заменили — результат 0. Развели руками и отправили ……………

Думаю про кореляцию датчиков, и загаженную заслонку и егр (несколько авто попадалось) Разобрали а там писец умер и всё собой закрыл. Отмыли, почистили, собрали,адаптировали заслонку, завели прогрели до 80 , а ошибка P010100 так и висит и не стирается (хотя адаптация прошла ок) В результате блок в аварийке и отключает турбину (давление выше 1.05 не поднимается — в основном висит 0.98) Проводку проверил, до блока под нагрузкой -ок.

Если у кого есть какие мысли — подскажите.

Если кто богат схемкой на это блок — тоже не помешает

Ever started up your Mercedes and wondered what the P0101 error code means? If the malfunction indicator light (MIL) appears on your Mercedes Benz dashboard, this indicates the car’s on-board diagnostics sensor (OBD-II/OBD 2) has identified a problem regarding the mass air flow sensor (MAF Sensor).

What is the Mass Air flow (MAF) sensor?

The MAF sensor also known as meter is located after the air filter, in the engine intake. It measures the amount of air that enters the engine via the throttle valve. Mass air flow sensor takes the form of a heated film through which an electric current passes from your car’s Engine Control Module (ECM), which helps to control its temperature. The intake air reduces the heat of this film, so in instances of greater airflow, the ECM needs to generate more electric current to stabilise the MAF’s temperature.

What are the main causes?

Your dashboard will display the P0101 error code when your car’s diagnostics note that the frequency readings from the MAF sensor are outside of its expected range.

The most common causes of the P0101 error code include a dirty or clogged air filter, a cracked or damaged air intake, or even the MAF sensor itself being contaminated or damaged. All of these factors would cause your Mercedes’ system to take incorrect or unexpected sensor readings that would alert the car’s systems to the issues with your car, resulting in the P0101 diagnostics trouble code (DTC).

Symptoms of a bad MAF sensor

There are a number of signs that there might be problems with your Mercedes’ MAF sensor. These include loss of engine power, bad gear shifting — changing gears only at high RPM, the engine stalling after starting, hesitation and jerking during acceleration, the engine hiccuping, or excessively rich or lean idling.

These are the most common fault codes for malfunctioning MAF:

• P0101 — Mass or Air Flow Volume Sensor Circuit Range/Performance
• P010162 P0101-62 — Mass Air Flow Sensor 1 has a malfunction the signal comparision is faulty
• P0100 — Mass Air Flow MAF sensor Circuit Malfunction
• P0102 — Mass Air flow MAF Circuit Low Voltage Input signal
• P0103 — Mass Air flow MAF Circuit High Voltage Input signal
• P0104 — Mass Air flow MAF Circuit Intermittent
• P0101FA P0101FB P0101FC Mass air flow sensor 1 has a malfunction
• P0101FD P0101(FD) Mass Air Flow MAF sensor/volume air flow VAF sensor — range/performance problem
• P0101 Mass air flow MAF sensor/volume air flow VAF sensor — range/performance problem

How to fix P0100 P0101 P0102 P0103 P0104 error codes

As the P0101 trouble code relates to internal damage, there’s not much that can be done at the roadside to solve the issue. With the air cooling system being potentially torn or clogged up you’d need to work with internal parts to resolve the problem, so you’d be best off asking a fully qualified mechanic. However, this is an issue that can be prevented before it starts.

P0101FA P0101FB P0101FC Diagnostic Trouble codes cause:

• Seal under engine control unit compressed
• Air filter cartridge/element slats distorted
• Leakage in intake system

These causes just apply to above 3 DTC on mercedes-benz cars.

Tips on preventing the P0101 error code

Ensure that your filter is always dust-free, dirt-free and oil-free to make sure the filter is effective. If this doesn’t work, you may need to replace the air filter. If after this you find it still doesn’t work, the enclosure for the air filter could need replacement to make sure the entire system is functional.

Can problems with the MAF sensor cause transmission problems?

Yes! It’s essential that you do your best to prevent a bad MAF sensor, as it can cause automatic transmission problems by changing the shifting pattern. It can also lead to a fault in your car’s engine computer not recognising your correct fuel level, which is why you may find your Check or Service Engine light starts blinking.
