If the code comes back it may be necessary to replace the mass air flow sensor. One of the key sensors in this operation is the MAF sensor.
First learn more about your MAF sensor inspect your vehicle for typical symptoms and look for common causes in order to find the right solution.
Mass or volume air flow sensor a circuit low. This wire is positioned in the air stream and is heated by the electrical current that the voltage produces. Youll notice if the tailpipes eject black smoke or when the engine runs rough or backfires. Powertrain – Fuel and Air Metering – ISOSAE Controlled.
Can also be caused by a bad or. How To Clean a Mass Airflow Sensor In-depth detailed version. When the PCM perceives the sensor or its circuit is malfunctioning OBD-II code P0101 is triggered.
P0100 Mass Air Flow Circuit Malfunction P0101 Mass Air Flow Circuit RangePerformance P0102 Mass Air Flow Circuit Low P0103 Mass Air Flow Circuit High P0104 Mass Air Flow Circuit Intermittent Trouble codes P0171 System Too Lean Bank 1 and P0174 System Too Lean Bank 2. The difference between the two codes is that the PCM has identified the sensor output as faulty for a P010C code. Its job is to measure the density and therefore the volume of filtered air that is drawn into the engine.
If the code comes back it may be necessary to replace the mass air flow sensor. Brands include but are not limited to Toyota Infiniti Nissan Jaguar Audi Mercedes Dodge Hyundai Chevy Ford etc. P0102 Mass or Volume Air Flow A Circuit Low Home Forums Stay Dirty Lounge Service and Repair Questions Answered Here P0102 Mass or Volume Air Flow A Circuit Low This topic contains 6 replies has 5 voices and was last updated by Cameron McCoy 4 years 11 months ago.
The mass airflow MAF sensor is a device that is mounted on the air intake. The mass air flow MAF sensor part of your vehicles electronic fuel injection system is responsible for calculating the total amount of air entering the engine. This code is similar to P0100 MAF sensor circuit malfunction.
Reset code and drive vehicle. Reset code and drive vehicle. A constant voltage is applied to a heated wire.
Before replacing the mass air flow sensor try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. The troublecode P0102 is set when the MAF sensor signal voltage or frequency is below expected values. P0102 – Mass Air Flow Sensor A Circuit Low Theory of Operation The Mass Air Flow MAF Sensor is a frequency based device.
It gives off a low voltage output to the Engine Control Unit. P0101 Mass or Volume Air Flow A Circuit RangePerformance P0102 Mass or Volume Air Flow A Circuit Low Input P0103 Mass or Volume Air Flow A Circuit High Input. Closely related MAF circuit trouble codes include.
If the code comes back it may be necessary to replace the mass air flow sensor. Mass or Volume Air Flow Circuit Low What does that mean. A faulty MAF sensor can cause your vehicle to run too rich or run too lean.
Most common cause of a p0101 Mass Air Flow MAF CircuitPerformance MalfunctionCode P0101 DefinitionMass Air Flow MAF CircuitPerformance MalfunctionM. Hot-wire MAF sensors often become dirty causing a P0102 code. MAF Sensor Circuit Low Frequency Conditions.
The P0102 code is the code for a problem with the Mass Airflow MAF Sensor. As air flows acro. 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.
Reset code and drive vehicle. The difference between the two codes is that the PCM has identified the sensor output as faulty for a P0102 code. The troublecode P010C is set when the MAF sensor signal voltage or frequency is below expected values.
This code is similar to P0100P010A MAF sensor circuit malfunction. 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. When this happens you need to know how do I fix trouble code P0102.
A trouble code P0102 is triggered when there is low airflow registered by the Mass Air Flow or MAF sensor. Engine runtime over 2 seconds engine speed more than 300 rpm system voltage more than 10v throttle position less than 50 then the PCM detected that the MAF sensor input was 10 hertz or less less than 300 Hz on 74L condition met for over 250 ms. 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.
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. This diagnostic trouble code DTC is a generic powertrain code which means that it applies to OBD-II equipped vehicles that have a mass airflow 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.
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.
