What causes low voltage in MAF sensor?
The MAF Sensor has low voltage output problems which may have several causes. The source of the problem is the sensor range voltage is lower than normal or required by the ECU to function properly. The most obvious problem is restricted airflow from the air cleaner to the MAF sensor which can be a clogged air filter.
What voltage should MAF idle at?
Depending on your MAF sensor, your voltage reading should be between 0.60 to 0.80 volts at idle. If your reading indicates 12 volts or pretty close to it, you are probing the power wire, not the signal wire).
What does the code p0102 mean on a MAF sensor?
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. 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).
What is the trouble code for a MAF sensor?
Note: Some MAF sensors also incorporate an air temperature sensor, which is another value used by the PCM for optimal engine operation. Closely related MAF circuit trouble codes include P0100, P0101, P0103, and P0104. Photo of a MAF sensor: What are some possible symptoms? Symptoms of a P0102 code may include:
What causes the mass airflow ( MAF ) sensor to have low voltage?
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). What causes the P0102 code? The MAF Sensor has low voltage output problems which may have several causes.
What is the trouble code for mass airflow?
P0102 is a diagnostic trouble code (DTC) for “Mass Airflow (MAF) Circuit Low Voltage 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. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic.
