What are the symptoms of a bad MAF sensor?
The symptoms of a bad mass air flow sensor include a car that is difficult to start, bad fuel economy, a rough idle, lack of power especially when accelerating and sometimes a fuel smell from the exhaust fumes. A properly functioning MAF sensor is vital for an engine to run efficiently.
How to clean the mass air flow sensor?
Pull the hood release and open the hood. Locate the MAF sensor next to the engine air filter housing. Unplug the mass air flow sensor electrical connector. Remove the two screws that hold the MAF sensor secure and remove the MAF sensor. Spray 8 to 12 spurts of MAF sensor cleaner on the exposed plate. Allow the MAF sensor to dry and reinstall.
Is there a problem with the MAP sensor?
If “intake manifold pressure” represents the value of the MAP sensor, the MAP sensor of my car may have a problem. I replaced PCV valve, but not resolving the problem. I found some rules to pop up P0101 code in my car.
What does it mean when your car is in limp mode?
Known as the limp / fail safe / emergency mode is when your transmission is stuck in one gear and doesn’t shift. In this condition, you only get speeds up to 30 mph max. Why does this happen? When the sensor input values from the different sensors inside the transmission]
What does p0100 mean on a MAF circuit?
P0101 Mass or Volume Air Flow “A” Circuit Range/Performance P0102 Mass or Volume Air Flow “A” Circuit Low Input P0103 Mass or Volume Air Flow “A” Circuit High Input P0104 Mass or Volume Air Flow “A” Circuit Intermittent Photo of a MAF sensor:
What is the trouble code for the MAF sensor?
The troublecode P0100 is set when the MAF sensor circuit is malfunctioning. This code is similar to P0104 – MAF sensor circuit intermittent. The difference between the two codes is the consistency of the malfunction in the MAF sensor circuit. Troubleshooting will be the same for both codes.

What should I do if I Change my MAF?
As others have stated… After you changed the MAF you needed to clear your code… Without a tool you simply disconnect the battery for a few minutes. Then test the vehicle. IF you get another MAF code with the new sensor and after batt disconnect… Your air filter is clogged. If the new MAF doesnt detect proper airflow it will register as a bad MAF.
What causes a check engine light on an OBD II?
Also consider that an MAF check engine code can be due to a vacuum leak; i.e. unrelated to the MAF sensor. You could try the experiment. As a test, purposely introduce a vacuum leak on an OBD II car with no codes. You’ll likely immediately get a check engine light and a code for the MAF sensor or for the o2 sensor.
What happens when I Change my MAF sensor?
When you change a MAF sensor, you need to disconnect the battery for about 10 minutes so the computer forgets the learned parameters and resets to the factory parameters. Then it goes into learn mode and may take a little while before it learns all the parameters of the new MAF sensor.
What to do if you get a bad MAF code?
IF you get another MAF code with the new sensor and after batt disconnect… Your air filter is clogged. If the new MAF doesnt detect proper airflow it will register as a bad MAF. I would remove or replace your air filter and test…straight away.
