How to fix P0100 P0101 P0102 P0103 P0104 error codesĪs the P0101 trouble code relates to internal damage, there’s not much that can be done at the roadside to solve the issue.
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. There are a number of signs that there might be problems with your Mercedes' MAF sensor. 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). 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. 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 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. 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. It measures the amount of air that enters the engine via the throttle valve. The MAF sensor also known as meter is located after the air filter, in the engine intake. 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).
