Can a dirty throttle body cause a P0101?
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). A dirty throttle body will need to be cleaned and the intake will have to be tested for vacuum leaks.
Can you drive with a P0101 code?
The P0101 code will not prevent the car from driving but it is advisable to check it out as soon as possible. The MAF sensor issue can cause excessive fuel consumption, rough operation and difficulty starting in certain circumstances. Sustained driving can cause internal problems in the engine.
Where is a Mass airflow sensor located?
The mass air flow sensor (MAF) is a key component of the electronic fuel injection system in a car. It is located between the air filter and the engine's intake manifold. In some cars, the intake air temperature (IAT) sensor is built into the mass air flow sensor.
How do you reset the MAF sensor?
Start engine and warm it up to normal operating temperature.Turn ignition switch OFF.Disconnect mass air flow sensor harness connector.Restart engine and let it idle for at least 5 seconds.Stop engine and reconnect mass air flow sensor harness connector.Make sure DTC P0102 is displayed.Erase the DTC memory.More items...•

Can an O2 sensor cause P0101?
If your O2 sensors or mass airflow sensors fail, as mentioned above, they can cause a P0101 code to display, and can also cause other problems for your engine over time.
Can a dirty air filter cause a mass air flow sensor?
Symptoms of a dirty filter The air filter may be the MAF sensor's first line of defense via the engine's air intake system, but a clogged, low quality or dirty air filter can actually become the source of MAF sensor damage if any contamination bypasses it.
Can you clean a mass air flow sensor?
You can clean rather than replace the expensive mass air flow sensor. Clean your MAF (Mass Air Flow) sensor when it's dirty rather than replace this $300 part. It's quick and easy with some handy tools and a spray.

What is the severity of P0101?
Code P0101 Severity – Moderate. Code P0101 does not pose any danger to the driver and will not prevent the vehicle from running. However, it will cause an increase in fuel consumption and rough operation. Sustained driving can lead to internal engine failure.
How to clean a MAF sensor?
Do this by spraying each side of the MAF sensor for 3-5 seconds, waiting 10 seconds, and then spraying it again for 3-5 seconds. Do not wipe it.
What is the code for a mass air flow sensor?
The mass air flow (MAF) sensor measures the amount of air entering the engine. Check engine light code P0101 is set when the measurement of air entering the engine by the mass air flow sensor is outside of the manufacturer’s specified range.
