mass air flow sensor code p0102
It consists of a hot film that is supplied with electric current from the Engine Control Module. When code P0102 is set there is a low voltage output to the ECM PCM or ECU depending on your car type check your owners manual for your specific car.

The code is set when the ECMPCM perceives a problem with the mass airflow MAF sensors performance.
. The troublecode P0102 is set when the MAF sensor signal voltage or frequency is below expected values. As air flows across it it cools down. The P0102 error code usually indicates the mass air-flow MAF sensor is not receiving enough air from the engine.
It should be considered a high priority to fix as the MAF sensor not reading properly can. Leakage of left air into the engine after the flow meter can also be a problem. P0102 INFINITI Mass or Volume Air Flow Circuit Low Input P0102 ISUZU Mass Air Flow Sensor Circuit Low Frequency.
The temperature of the hot film is controlled by the ECM a certain. It measures the intake flow rate by measuring a part of the entire intake flow. Symptoms of the general failure code P0102 The Check Engine lamp lights up.
The direct measurement of the air entering the engine is more accurate than calculating the airflow from the Manifold Absulte Pressure MAP the Intake Air Temperature IAT and the engine speed speeddensity. P0102 - Mass Air Flow Sensor A Circuit Low Theory of Operation The Mass Air Flow MAF Sensor is a frequency based device. P0102 is the generic DTC Data Trouble Code for Mass or Volume Air Flow Circuit Low Input and it would most likely be a fault with the MAF Mass Air Flow sensor.
It measures the intake flow rate by measuring a part of the entire intake flow. The P0102 code is the code for a problem with the Mass Airflow MAF Sensor. MAF Sensor Circuit Low.
DTC P0102 will be set if the signal from the MAF sensor is below the possible range of a normally operating MAF sensor. It means the the Mass Air Flow MAF circuit is low and that it is not performing within its specified operating range. P0102 HONDA Mass Air Flow Sensor Circuit Low Voltage.
The Code P0102 indicates that the Mass Air Flow Sensor MAF is reporting inaccurate values. The PCM detects that the actual MAF sensor frequency signal is not performing within the normal expected range of the calculated MAF value. The Mass Air Flow MAF sensor measures the amount of air ingested by the engine.
Reset code and drive vehicle. What the P0102 code means P0102 is the general code for a problem with the Mass Airflow MAF Sensor having a low voltage output to the Engine Control Unit ECU. In order for the ECU to function properly the MFA flow rate must be within a preset range of values and if the MFA communicates a number too low the ECU wont function effectively.
The difference between the two codes is that the PCM has identified the sensor output as faulty for a P0102 code. Chevy Silverado P0102. Throttle angle below 75.
The code P0102 is set when the signal from the mass air flow sensor is lower than expected. Diagnostic trouble code DTC P0102 isnt in every vehicles code library but whenever it appears it means Mass Air Flow MAF Circuit Low. The Mass Airflow MAF sensor measures the amount of air entering the engine.
It means the the Mass Air Flow MAF circuit is low and that it is not performing within its specified operating range. P0102 HYUNDAI Mass or Volume Air Flow Circuit Low Input. Above conditions present for over 05 seconds.
Conditions for Setting the DTC The engine is running. Hot-wire MAF sensors often become dirty causing a P0102 code. The vehicle will run rough.
When P0102 OBD2 error code is set it means that the powertrain control module ECM has detected a failure of the MAF sensor or its circuit. P0102 is a very common trouble code in the Chevy Silverado. A constant voltage is applied to a heated wire.
This P0102 diagnostic trouble code DTC means that there is a low condition detected in the Mass Air Flow MAF sensor or circuit. This wire is positioned in the air stream and is heated by the electrical current that the voltage produces. The engine computer PCM uses the mass air flow signal to calculate the amount of fuel to be injected.
Action Taken When the DTC Sets. OBD-II Trouble Code P0102 Description Mass or Volume Air Flow Circuit Low Input Condition This means that a vehicles PCM Powertrain Control Module has determined that the incoming signal from the engines mass air flow sensor is below the lower threshold of its operating range. This can happen for multiple reasons that include bad connections from previously required wiring corrosion in electrical connectors and improper installations of aftermarket components.
MAF signal frequency is below 1200 Hertz. We will cover exactly what that means and potential fixes for it below. The Mass Air Flow sensor is designed to measure the amount of air taken into the engine.
As a result the PCM has determined this data to be irrational. P0102 code tech notes Before replacing the mass air flow sensor try replacing the air filter and cleaning the Mass Air Flow MAF sensor with low compress air or mass air flow sensor cleaner. P0102 JEEP code description The Mass Air Flow MAF sensor is placed in the stream of intake air.
It gives off a low voltage output to the Engine Control Unit. P0102 HUMMER Mass or Volume Air Flow Circuit Low Input. What is P0102 CHEVROLET code meaning.
It consists of a hot film that is supplied with electric current from the Engine Control Module ECM. Read more about mass air flow sensor Symptoms Causes. This code is similar to P0100 MAF sensor circuit malfunction.
P0102 GMC Mass or Volume Air Flow Circuit Low Input. P0102 ACURA Description The Mass Air Flow MAF sensor is placed in the stream of intake air. The sensor calculates the airflow and reports to the Powertrain Control Module PCM and the PCM can determine the volume of fuel that enters the engine.
We will cover exactly what that means and potential fixes for it below. The mass air flow or MAF sensor measures the amount of air entering the engine. If the code comes back it may be necessary to replace the mass air flow sensor.
November 2 2018 by Jason. Up to 8 cash back Mass Airflow MAF Circuit Low Voltage Input The code P0102 code is often associated with P0100 P0101 P0103 or P0104 trouble codes as they are closely related. P0102 is a very common trouble code in the Chevy Traverse.
The smoke coming out of the tailpipe is black. The MAF sensor could be dirty or faulty and there might even be restricted air flow to the MAF sensor like a plugged up air filter. The MAF sensor is mounted between the air filter and the throttle body.
