· A bad mass air flow sensor may cause a lot of problems with your car engine, and therefore it is not recommended to drive with it. If your engine is running fine, you can drive slowly to the closest repair workshop without problems, though.

· The mass air flow (MAF) sensor , part of your vehicle’s electronic ... A bad MAF sensor can cause too much fuel to be left in the combustion chamber, ... However, it''s also a good idea to have a mechanic check your vehicle for damage.

· Follow These Tricks! 3. Engine idles roughly or halts. These are the bad MAF sensor symptoms that indicate that the sensor is completely out of order. In that case, the car’s computer cannot control the fueltoair ratio because the sensor does not send any information to it. As a result, the engine either halts or idles roughly.

MASS AIR FLOW SENSOR INVESTIGATION. No dealership or service provider, when contacted, has ever been able to provide us with evidence to support this "myth," and in fact, our investigations have revealed that even authorized dealerships are simply speculating and do not have the test equipment necessary to know whether the sensor has failed or why.

· Have you noticed your car’s engine drop in acceleration together with a check engine light on your dashboard lately? The chances are that your car’s intake air temperature sensor (IAT) is damaged and that it should be fixed immediately to avoid any serious damage to the engine. In this article, you will learn the signs of a bad IAT sensor.

· The mass air flow (MAF) sensor, part of your vehicle’s electronic fuel injection system, is responsible for calculating the total amount of air entering the contaminated or failed mass air flow sensor cannot measure the amount of air flow correctly. This causes the engine computer to miscalculate the amount of injected fuel, causing additional damage to …

The use of an absolute filter confirmed that no oil came off the KN filter tested, even in these harsh conditions. We have tested many MAF sensors claimed to be damaged. We can fully diagnose their condition and likely cause of failure. For a full discussion of our MAF sensor test protocol and findings, see KN Mass Air Flow Testing Results ...

· Leaking head gasket. Faulty oxygen sensor. Defective mass airflow sensor. Faulty throttle position sensor. Any of these components can cause a cylinder 4 to misfire and be the root cause of a P0304 engine code. However, …

· If your car’s Engine Control Module doesn’t detect that the mass air flow sensor has gone bad, then driving with a bad mass air flow sensor will lead to additional problems. If the MAF sensor is underestimating air flow, the car will run lean and might overheat, burning out your catalytic converter and even burning a hole in a piston in the worstcase scenario.

· When you put your key into the ignition and twist it, you may find the engine is difficult to turn over or start altogether. This is understandable with a bad mass air flow sensor because it will cause the internal combustion chamber to have an …

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.

· Quick test to tell if Mass Air Flow Sensor is bad or dirty which could be causing your car or truck to run bad or keep cutting off.

· the check engine light came on a little bit ago and we got it tested and it was the mass air flow sensor, ... 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 ... you may taking your car to a mechanic, and you may have ...

· The chances are that your car’s intake air temperature sensor ... If you experience some small hiccups on idle, it can be a faulty IAT sensor. 5. Misfires. ... Mass air flow values on idle are almost identical on both banks. About 1819 kg/s if I remember correctly.

· A bad mass airflow sensor can leave your Ford F150’s engine running rough, or even inoperable. A MAF sensor measures the density of the air entering the intake manifold. It passes this information onto your F150’s ECU. The ECU uses this information along with other sensor data to control the amount of fuel that enters the combustion chamber.

· The mass air flow sensor monitors air intake as it is mixed with fuel prior to being injected into the motor. This sensor relays vital information to the ECM which uses this to make adjustments to fuel supply to the motor. A dirty or faulty sensor can cause an imbalanced air/fuel load to be supplied to the motor which results in an over fueling ...

The symptoms of a bad mass air flow sensor include low engine power, poor fuel economy, an engine that won''t start, a check engine light on the dash and a gas smell from the exhaust fumes. A bad mass air flow sensor is often the likely culprit if your car isn''t running as it should.

· KEEPING THE MASS AIR FLOW SENSOR PRECISE. The precision that the MAF sensor is expected to deliver at makes it a powerful but delicate device; it can be easily contaminated by dirt, debris and oil. Contamination can occur as early as 18,000 to 25,000 miles, depending on the model of the vehicle. Sensors for turbodiesel engines in particular ...

· A bad mass air flow sensor is often the likely culprit if your car isn’t running as it should. The job of the mass air flow sensor is to keep track of the amount of air coming in through the air filter, so that the ECU can adjust the amount of fuel getting into the engine.

· If your code scanner indicated that there were problems with the mass air flow sensor or oxygen sensor, they may be the cause of your misfire. The mass air flow sensor is located on the intake pipe, usually just past the air filter. Oxygen sensors, on the other hand, are found on the vehicle’s exhaust, usually before the catalytic converter ...

The mass air flow (MAF) sensor, part of your vehicle’s electronic fuel injection system, is responsible for calculating the total amount of air entering the engine. A faulty MAF sensor can cause your vehicle to run too rich or run too lean. You’ll notice if the tailpipes eject black smoke or when the engine runs rough or backfires.

A bad mass air flow sensor can cause serious damage to your vehicle engine and so you have to be fully informed of the signs and symptoms of bad mass air flow sensor to avoid costly repair cost that might result from not fixing or resolving your car MAF sensor issue early enough from when it went bad.

· A mass airflow sensor (MAS) determines the mass of air entering a vehicle''s fuel injection engine, and passes that data to the Engine Control Unit, or ECU. The air mass information is necessary for the ECU to correctly balance and deliver the correct amount of fuel to the engine. When a vehicle''s mass airflow sensor is faulty or defective it can cause a …

· Category: automotive auto parts. /5 (5,822 Views . 45 Votes) As a result, a bad mass air flow sensor causes various driveability problems, including a nostart, stalling, lack of power and poor acceleration. A problem with the air flow sensor could also alter the shifting pattern of the automatic transmission. Click to see full answer.

Even a dirty MAF sensor can cause a lean code and/or misfire to occur. The engine may be stalling because it isn’t getting enough throttle opening. The cause is often a problem in the idle air control system. The first thing to check is the intake vacuum with a vacuum gauge. On most vehicles a normal reading is 17 to 21 inches Hg.
