What causes code po101?
The mass airflow sensor (MAF) measures the amount of air entering the engine. The OBD-II code P0101 is set when the signal from the mass air flow sensor is out of expected range, or in other words, the MAF sensor doesn’t work properly.
What does code p0101 on mass air flow sensor mean?
The code P0101 means that the signal from the mass air flow sensor (MAF) is out of expected range. The MAF sensor is installed in the engine intake, right after the air filter. it measures the amount of air entering the engine through the throttle valve.
What is the problem code for mass airflow?
P0101 is the general code for a problem with the Mass Airflow Sensor (MAS) operating range and/or an engine performance issue. What causes the P0101 code? The most common source of the problem is the sensor range of the MAF sensor being outside of the normal operating range.
What are the possible causes of p0101 Mercedes-Benz?
P0101 MERCEDES-BENZ Possible Causes 1 Faulty mass air flow sensor 2 Intake air leaks 3 Dirty mass air flow sensor 4 Dirty mass air filter 5 Mass air flow sensor harness is open or shorted 6 Mass air flow sensor circuit poor electrical connection
Can a leaking exhaust manifold cause a lean condition?
Absolutely, a leaking exhaust manifold can cause those codes. Those codes do NOT mean the O2 sensors are bad, it means a lean condition has been detected. Do not replace O2 sensors when you have those codes.

What causes a fault reading on a MAF sensor?
The wiring or MAF sensor may be too close to higher voltage consuming components. This includes alternators, ignition wires, etc. which can cause interference in the output signal to the ECU. A vacuum leak can also cause a fault reading and can lead to other problems that may indicate several codes at the same time.
What are the causes of the code p0401?
Causes of Code P0401 1 Clogged or restricted EGR passages due to excess carbon 2 Faulty EGR valve 3 EGR temperature sensor is covered with carbon
