mass air flow sensor code p0102
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. It consists of a hot film that is supplied with.

The MAF sensor measures the amount of air that is entering the engine.
. The MAF sensor is an air flow meter that measures the amount of air in the sensor bore. It gives off a low voltage output to the Engine Control Unit. What Does the P0102 CHEVROLET Code Mean.
The MAF sensor produces a frequency signal which can be monitored using a scan tool. The code P0102 is set when the signal from the mass air flow sensor is lower than expected. What Does the P0102 TOYOTA Code Mean.
Sensor design may vary for your model and year. 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. 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.
A MAF that is reading too low will then result in not enough fuel being injected and as a result the engine would be operating in a lean condition. Updated July 11 2021. This code sets if the ECM or PCM determines theres a problem with the performance of the mass airflow sensor which is found between the throttle body and air filter.
It means the the Mass Air Flow MAF circuit is low and that it is not performing within its specified operating range. Not every vehicle has a P0102 DTC. P0102 is a very common trouble code in the Chevy Silverado.
The vehicle will run rough. The MAF sensor must be within the correct voltage range for the Engine Control Unit ECU to function correctly. The P0102 code is the code for a problem with the Mass Airflow MAF Sensor.
The P0102 error code usually indicates the mass air-flow MAF sensor is not receiving enough air from the engine. Mass or Circuit Airflow MAF Circuit Low Voltage Input. The code P0102 is set when the signal from the mass air flow sensor is lower than expected.
Get this code fixed within the next month. The ECM detects the air flow by means of this current change. The mass air flow or MAF sensor measures the amount of air entering the engine.
The frequency will vary within a range of around 2000 Hertz at idle to near 10000 Hertz at maximum engine load. LOW Continued driving for a short period of time is okay. OBD-II Code P0102 is defined as a Mass or Volume Air Flow Circuit Low Input.
The Mass Air Flow MAF sensor is integrated with the multifunction intake air sensor. It measures the intake flow rate by measuring a part of the entire intake flow. The engine computer PCM uses the mass air flow signal to calculate the amount of fuel to be injected.
The PCM detects that the actual MAF sensor frequency signal is not performing within the normal expected range of the calculated MAF value. However when it appears with your vehicle it means that the mass airflow MAF circuit is reading low voltage. What Does the P0102 Code Mean.
P0102 Code - Mass or Volume Air Flow Circuit Low Input. It consists of a hot film that is supplied with electric current. This can happen for multiple reasons that include bad connections from previously required wiring corrosion in electrical connectors and improper installations of aftermarket components.
The mass air flow or MAF sensor measures the amount of air entering the engine. It is important to complete the entire diagnostic process when diagnosing the P0102 code. P0102 CHRYSLER code description The Mass Air Flow MAF sensor is placed in the stream of the intake air.
It should be considered a high priority to fix. P0102 is an OBDII trouble code indicating that the mass air flow sensor MAF is reporting inaccurate values. The Engine Control Module ECM uses the MAF sensor signal to provide the correct fuel delivery for all engine speeds and loads.
This P0102 diagnostic trouble code DTC means that there is a low condition detected in the Mass Air Flow MAF sensor or circuit. Ad Air Filter diagnose diagnosis electrical Electronics engine fuel economy Intake Intake Manifold mass air flow OBD OBD 2 codes obd codes P0102 performance Replacement sensor troubleshooting. 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.
The Diagnostic Trouble Code DTC will be set when the ECM detects that the MAF Sensor Signal is less than the factory specifications. It measures the intake flow rate by measuring a part of the entire intake flow. The Mass Air Flow MAF sensor is placed in the stream of the intake air.
Up to 8 cash back P0102 is a diagnostic trouble code DTC for Mass Airflow MAF Circuit Low Voltage Input. We will cover exactly what that means and potential fixes for it below. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic for 11499.
P0102 Mass or Volume Air Flow Circuit low Input. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. P0102 is a diagnostic trouble code for Mass Air Flow MAF sensor Circuit Low Voltage Input This means a problem with the MAF sensor.
DTC P0102 will be set if the signal from the MAF sensor is below the possible range of a normally operating MAF sensor. P0102 - Mass Air Flow Sensor Circuit Low.
