If the problem is fixed the code P0102 will clear itself after driving.
. The P0102 error code usually indicates the mass air-flow MAF sensor is not receiving enough air from the engine. P0102 is a very common trouble code in the Chevy Silverado. It is important to complete the entire diagnostic process when diagnosing the P0102 code.
The vehicle will run rough. This code is similar to P0100 MAF sensor circuit malfunction. The air filter may be very dirty causing the sensor to show low air flow voltage due to air flow restriction.
LOW Continued driving for a short period of time is okay. The Mass Air Flow MAF sensor is placed in the stream of the intake air. However when it appears with your vehicle it means that the mass airflow MAF circuit is reading low voltage.
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. What Does the P0102 Code Mean. 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.
It measures the intake flow rate by measuring a part of the entire intake flow. The mass air flow MAF sensor may be dirty. The difference between the two codes is that the PCM has identified the sensor output as faulty for a.
Possible solutions for general code DTC P0102 To resolve DTC P0102 OBD2 you can do the following. The Diagnostic Trouble Code DTC will be set when the ECM detects that the MAF Sensor Signal is less than the factory specifications. Make sure they are not broken or worn.
The ECM detects the air flow by means of this current change. It means the the Mass Air Flow MAF circuit is low and that it is not performing within its specified operating range. Get this code fixed within the next month.
It consists of a hot film that is supplied with electric current. Up to 8 cash back P0102 Trouble code definition 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. The MAF sensor must be within the correct voltage range for the Engine Control Unit ECU to function correctly.
The frequency will vary within a range of around 2000 Hertz at idle to near 10000 Hertz at maximum engine load. Conditions for Setting the DTC. Replacing the sensor is easy.
The P0102 code is the code for a problem with the Mass Airflow 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. 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 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 sensor costs from 70 to 350. Often the solution for the code P0102 is to replace the mass air flow sensor if no other problems are found.
P0102 is a diagnostic trouble code for Mass Air Flow MAF sensor Circuit Low Voltage Input This means a problem with the MAF sensor. It consists of a hot film that is supplied with electric current. Not every vehicle has a P0102 DTC.
A poor-quality part can also cause the code P0102. 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. The MAF sensor measures the amount of air that is entering the engine.
This P0102 diagnostic trouble code DTC means that there is a low condition detected in the Mass Air Flow MAF sensor or circuit. P0102 Code - Mass or Volume Air Flow Circuit Low Input. The MAF sensor produces a frequency signal which can be monitored using a scan tool.
MAF sensor may be damaged. Check all cables and their corresponding connectors to the mass air flow MAF sensor. Check for air leaks in the intake system.
What Does the P0102 ACURA Code Mean. We will cover exactly what that means and potential fixes for it below. Its best to use an OEM sensor.
It measures the intake flow rate by measuring a part of the entire intake flow. Mass or Circuit Airflow MAF Circuit Low Voltage Input. It should be considered a high priority to fix.
The Mass Air Flow MAF sensor is integrated with the multifunction intake air sensor. This can happen for multiple reasons that include bad connections from previously required wiring corrosion in electrical connectors and improper installations of aftermarket components. How serious is the P0102 code.
P0102 ACURA code description The Mass Air Flow MAF sensor is placed in the stream of the intake air. The Engine Control Module ECM uses the MAF sensor signal to provide the correct fuel delivery for all engine speeds and loads. It gives off a low voltage output to the Engine Control Unit.
