What causes the DTC p0101 MAF sensor to fail?
Depending on year, make, and model, DTC P0101 may have a number of causes. Here are some of the most common. Toyota / Lexus – The hot-wire MAF sensor is notoriously susceptible to oil contamination and aftermarket air filter contamination.
Can a split intake tube set DTC p0101?
Generally-speaking, if something looks out of place, then it probably is. In the case of a MAF sensor, contamination can just as easily set DTC P0101 as can a split intake tube. Usually, best practice dictates starting with the simplest and least expensive repair first.
What does the Check Engine Light code p0101 mean?
The mass air flow (MAF) sensor measures the amount of air entering the engine. Check engine light code P0101 is set when the measurement of air entering the engine by the mass air flow sensor is outside of the manufacturer’s specified range.

What does it mean when mass airflow sensor is incorrect?
Essentially, your vehicle’s PCM (powertrain control module) has detected that the input that it has been given by the mass airflow sensor is incorrect. To better understand what this fault is indicating, you must first understand what a mass airflow sensor is, and how it works.
What to do if your fault code is p0101?
Reset the fault codes and perform a road test using a live data scanner. If the P0101 code comes back, then follow the test procedure prescribed for that code. Inspect the electrical connector to insure it is securely attached. Disconnect it and then reinstall to insure fresh and clean electrical connection.
What does the p0101 Nissan MAF sensor mean?
P0101 NISSAN Meaning The Mass Air Flow (MAF) sensor is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake flow. It consists of a hot film that is supplied with electric current from the Engine Control Module (ECM). The temperature of the hot film is controlled by the ECMa certain amount.
What does p0101 mean on a VW Beetle?
One common engine code Volkswagen owners get is P0101. Whether it is a gas or diesel, the cause is the mass air flow (MAF) sensor, which measures the amount of air flowing into the engine. The sensor is likely overly sensitive. If the sensor detects the flow is more than 18% out of spec, it will trigger the engine light.
