Air filter has about 25K miles on it.

. Updated July 11 2021. Up to 8 cash back P0102 is a diagnostic trouble code DTC for Mass Airflow MAF Circuit Low Voltage Input. 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.

The code P0102 is set when the signal from the mass air flow sensor is lower than expected. OBD-II Code P0102 is defined as a Mass or Volume Air Flow Circuit Low Input The Mass Airflow Sensor MAF measures the amount of air entering the engine and the Engine Control Module ECM uses the information to determine the proper amount of fuel quantity and ignition timing. Mitsubishi Diagnostic Trouble Codes list.

This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. The code P0102 is set when the signal from the mass air flow sensor is lower than expected. The Mass Air Flow sensor is designed to measure the amount of air taken into the engine.

What Does the P0102 CHEVROLET Code Mean. The PCM detects that the actual MAF sensor frequency signal is not performing within the normal expected range of the calculated MAF value. Not seeing any vacuum or intake hose leaks.

P0102 - Mass Air Flow Sensor Circuit Low. 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. We will cover exactly what that means and potential fixes for it below.

21902 x64 Data version. The mass air flow MAF sensor may be dirty. The mass air flow or MAF sensor measures the amount of air entering the engine.

P0102 HUMMER Mass or Volume Air Flow Circuit Low Input. The frequency will vary within a range of around 2000 Hertz at idle to near 10000 Hertz at maximum engine load. Since P0102 has to do with the Mass Airflow Sensor which is a huge part of the Tahoes engine combustion process metering it is going to cause noticeable symptoms.

P0102 GMC Mass or Volume Air Flow Circuit Low Input. Diagnostic trouble code DTC P0102 isnt in every vehicles code library but whenever it appears it means Mass Air Flow MAF Circuit Low. P0102 INFINITI Mass or Volume Air Flow Circuit Low Input P0102 ISUZU Mass Air Flow Sensor Circuit Low Frequency.

The P0102 code is the code for a problem with the Mass Airflow MAF Sensor. Mass Air Flow Sensor G70 P0102 - 000 - Signal too Low. The engine computer ECM uses the mass air flow signal to calculate the amount of fuel injected read more how the MAF sensor works below.

Repair or change as needed. This P0102 diagnostic trouble code DTC means that there is a low condition detected in the Mass Air Flow MAF sensor or circuit. The engine computer PCM uses the mass air flow signal to calculate the amount of fuel to be injected.

Possible solutions for general code DTC P0102 To resolve DTC P0102 OBD2 you can do the following. 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. Check for air leaks in the intake system.

It means the the Mass Air Flow MAF circuit is low and that it is not performing within its specified operating range. It gives off a low voltage output to the Engine Control Unit. Make sure they are not broken or worn.

It should be considered a high priority to fix. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic for 11499. P0102 is a very common trouble code in the Chevy Silverado.

The P0102 error code usually indicates the mass air-flow MAF sensor is not receiving enough air from the engine. DTC P0102 will be set if the signal from the MAF sensor is below the possible range of a normally operating MAF sensor. The vehicle will run rough.

The MAF sensor is mounted between the air filter and the throttle body. Fuel mileage increased 3 to 4 miles per gallon. Saturday22January202213032932859 VCDS -- Windows Based VAGVAS Emulator Running on Windows 10 x64 VCDS Version.

P0102 HYUNDAI Mass or Volume Air Flow Circuit Low Input. The Mass Air Flow MAF sensor measures the amount of air ingested by the engine. Check all cables and their corresponding connectors to the mass air flow MAF sensor.

P0102 HONDA Mass Air Flow Sensor Circuit Low Voltage. Conditions for Setting the DTC. P0102 Mass or Volume Air Flow Circuit low Input.

The mass air flow or MAF sensor measures the amount of air entering the engine. This can happen for multiple reasons that include bad connections from previously required wiring corrosion in electrical connectors and improper installations of aftermarket components. OBD-II Trouble Code P0102 DescriptionMass 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.

The MAF sensor produces a frequency signal which can be monitored using a scan tool. MAF sensor may be damaged. The Code P0102 indicates that the Mass Air Flow Sensor MAF is reporting inaccurate values.

P0102 is a very common trouble code in the Chevy Tahoe. P0102 Mass Air Flow Signal Low Mass air flow sensor low output level P0103 Mass Air Flow Signal High Mass air flow sensor high output level P0112 Intake Air Temperature Sensor Signal Low Intake air. It means the the Mass Air Flow MAF circuit is low and that it is not performing within its specified operating range.
