Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor. Diagnosing GM Digital Mass Air Flow Sensors P0101
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 is the function of the p0106 GMC sensor?
P0106 GMC Meaning. The Manifold Absolute Pressure (MAP) sensor provides instantaneous manifold pressure information to the engine’s Engine Control Module (ECM). The data is used to calculate air density and determine the engine’s air mass flow rate, which in turn determines the required fuel metering for optimum combustion.
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.

If the code comes back, it may be necessary to replaced the mass air flow sensor. The cost to diagnose the P0101 GMC code is 1.0 hour of labor.
What does the p0101 code on the MAF sensor mean?
The P0101 code is set when the Powertrain Control Module (PCM) detects that the Mass Air Flow (MAF) sensor frequency is below a predetermined value. P0101 GMC Possible Symptoms. P0101 GMC Meaning. The Mass Air Flow (MAF) sensor measures the amount of air ingested by the engine.
Why does my Chevy S10 have a p0101 sensor?
Since P0101 has to do with the Mass Airflow Sensor, which is a huge part of a computer controlled engine’s combustion process metering. They include: If playback doesn’t begin shortly, try restarting your device. Videos you watch may be added to the TV’s watch history and influence TV recommendations.
