Quick Answer: What Causes A P0102 Code?

Can I use wd40 to clean MAF sensor?

Electrical contact cleaner will be fine.

Do not use carb cleaner or WD40!.

How much is a mass air flow sensor?

Many mass air flow sensors will cost around $100 to $150, however some will reach upwards of $400, especially in nicer German makes. Most of these sensors sit on the air induction system, so installation will not run very high, usually $20 to $50.

What does mass or volume air flow a circuit low mean?

P0102 – Mass or Volume Air Flow Circuit Low Input. P0102 is an OBDII trouble code indicating that the mass air flow sensor (MAF) is reporting inaccurate values. … A MAF that is reading too low will then result in not enough fuel being injected, and as a result the engine would be operating in a lean condition.

Can you 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 happens if I unplug my 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.

Can you bypass a MAF sensor?

Can you bypass MAF sensor? There is a sensor on the air intake called the mass air flow sensor. This sensor calculates how much air to mix with the fuel. You can bypass the MAF sensor, and allow the O2 sensor to calculate how much air is needed.

How can you tell if a mass airflow sensor is bad?

You may have a bad MAF sensor if you notice one or more of the following symptoms:A decrease in engine power.The engine vibrates (poor idling)The engine hesitates or stalls at acceleration.More frequent stops at the gas station.The engine surges at idling.Other driveability problems.More items…•

How much does it cost to replace MAF sensor?

To get your mass air flow sensor replaced, you will pay about $300, on average. The labor should cost you around $60, while parts are about $240. The prices vary based on where you go for servicing and what kind of car you have.

How long does it take for mass air flow sensor to reset?

about 10 minutesWhen 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.

Should I clean or replace MAF sensor?

The design and function of the mass air flow sensor Both are delicate and may be damaged if you try to clean them. For this reason, it’s better to replace the sensor than to attempt to clean it and continue using it. The MAF sensor measures the amount of air that comes into the system.

What codes can a mass air flow sensor cause?

The mass airflow sensor (MAF) measures the amount of air entering the engine. The OBD-II code P0101 is set when the signal from the mass air flow sensor is out of expected range, or in other words, the MAF sensor doesn’t work properly.

What are the symptoms of a mass air flow sensor going bad?

Symptoms of a Faulty Mass Air Flow Sensor The engine stalls shortly after starting. The engine hesitates or drags while under load or idle. Hesitation and jerking during acceleration. The engine hiccups.

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 .
