What Does Code Po102 Mean? 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).
How do I fix code po102? P0102 Diagnosis
Clear your Check Engine Light using your FIXD sensor and do a road test to see if your Check Engine Light comes back on (~20-50 miles should be a range).
Check your air filter and replace if needed.
Clean your MAF sensor to make sure that there are no pieces in the system that do not belong.

What are the symptoms of a bad mass air flow sensor? Symptoms of a Faulty Mass Air Flow Sensor
The engine is very hard to start or turn over.
The engine stalls shortly after starting.
The engine hesitates or drags while under load or idle.
Hesitation and jerking during acceleration.
The engine hiccups.
Excessively rich or lean idling.
What should happen if I unplug MAF sensor? If you disconnect the mass airflow sensor, then the car should keep running and still be able to start normally. This means that if your mass airflow sensor dies completely, then your car will stay running and surprisingly the car might run better without the mass airflow sensor.

What does error code P0101 mean?
Mass Airflow
P0101 is a diagnostic trouble code (DTC) for “Mass Airflow (MAF) Circuit Operating Range or Performance Problem”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

Is there a fuse for the mass airflow sensor?
There is a fuse for the maf sensor, but it is not the same one that runs most of the other stuff on that side of the engine bay. The code you get is for a dead maf, usually when the fuse pops.
Can a dirty air filter cause P0102?
The primary reason for a P0102 code is restricted airflow.

How long can I drive with a bad mass air flow sensor?
You can drive your vehicle with a bad mass air flow sensor for a while, but it is not advisable to continue doing so for a long time even if your car can still run and that is because, Ignoring your car MAF sensor problem can escalate beyond just the Mass air flow sensor problem to a more severe engine problem that
What makes a MAF sensor go bad?
Contamination is a key reason why MAF sensors fail and require replacement. As air, dirt and other debris get into the sensor, the parts become contaminated and fail. Drivers often notice sluggish performance, rough idling, poor acceleration or even stalling.
Should I clean or replace MAF sensor?
The design and function of the mass air flow sensor
Why does my car run better with MAF unplugged?
The MAF sensor measures air weight in grams per second and air temperature and if either of those two are off then the ECU may command a leaner or a richer mixture. By disconnecting the sensor the ECU switches to limp mode and the car may idle better .
Can I run my car with MAF unplugged?
If you unplug the mass air flow sensor the car will start. If you try to plug it in while it’s running the car will die.
Will a car run without MAF?
While the vehicle may run with a dirty or broken MAF, it will not be efficient and may cause mechanical damage to the engine due to running in a lean condition. A failed MAF sensor may not send any airflow information to the PCM.

Can a dirty air filter cause a P0101 code?
In vehicles with an oil-soaked aftermarket air filter, oil from the air filter can contaminate the MAF sensor element, causing the code P0101 or other MAF-related codes. In some Volvo cars, the code P0101 could be caused by a dirty throttle body or vacuum leaks in the PCV system (e.g. vacuum line to the oil separator).

Can a bad mass air flow sensor cause transmission problems?
As a result, a bad mass air flow sensor causes various driveability problems, including a no-start, stalling, lack of power and poor acceleration. A problem with the air flow sensor could also alter the shifting pattern of the automatic transmission. A bad MAF can cause hard or incorrect shifts.
