K&N Response to Mass Air Flow Sensor Concerns

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.

Does a Mass Airflow Sensor Need to be Programmed After ...

The MAF as it is commonly called is usually placed between the throttle and air cleaner. The MAF can get damaged and once it does, it causes many problems which could lead to engine failure or drastic reduction in performance. A faulty or damaged mass airflow sensor can cause rough idling to the engine and difficulties in starting. The MAF can also get dirty as time goes on due to an old or clogged air filter.

Mass Air Flow Sensor 101: How to Install It, Info, Tips ...

· To take full advantage of all that hard work, you can upgrade your mass air flow sensor. Your mass air flow sensor monitors the amount of air that comes into the engine by means of a thin wire or resistor. The computer reads the electrical resistance that the MAF sensor transmits. It does this as the air flows through it and cools its components down. The computer uses these readings to tell the fuel injectors how much or how little gasoline the vehicle needs to balance out the air …

What Happens If You Disconnect Mass Air Flow Sensor ...

· Well, the answer to that is no. If you disconnect the mass airflow sensor, then the car should keep running and still be able to start normally. This is because the computer in the car if it does not receive a reading from the mass airflow sensor, will estimate and supply a number that it thinks it is supposed to have.

How to Bypass the Cold Air Intake Sensor | It Still Runs

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. If you are using a cold air intake, the MAF sensor might not be calculating properly. This means you are not getting the added gas mileage that most cold air intakes advertise. You can bypass the MAF sensor, and allow the O2 sensor to calculate how much air is needed ...

Mass Air flow Sensor (MAF): how it works, symptoms ...

· Often if an air filter is not installed properly, or the air filter box is not closed, a piece of debris can get sucked into the mass air flow sensor (see this photo) and cause problems. Sometimes the debris can fall in during the air filter replacement. In this case, the repair is easy. The mass air flow sensor must be cleaned and the air filter must be reinstalled correctly or replaced.

Air Mass Sensors · Technipedia · Motorservice

The air mass sensor precisely measures the air mass that flows into the engine (“mass air flow”). The signal from the air mass sensor is used to calculate the injected fuel quantity. In diesel engines, it also controls the exhaust gas recirculation. It is an important component in air supply and helps reduce exhaust gas. A defective or contaminated air mass sensor can convey incorrect ...

Mass flow sensor - Wikipedia

A mass (air) flow sensor (MAF) is a sensor used to determine the mass flow rate of air entering a fuel-injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density with temperature and pressure. In automotive applications, air density varies with the ambient ...

How to Repair a Mass Air Flow Sensor | It Still Runs

A mass air flow sensor monitors the air coming in through the air intake system so that the vehicle's electronic control unit (ECU) can make adjustments to the air/fuel ratio. Adjustments to the fuel mixture are necessary to keep a vehicle running smoothly. Too much air and not enough fuel will cause the engine to run lean, causing the vehicle to potentially stall. Too much fuel, however, and ...

my mass air flow sensor has to be in backwards

By installing the MAF sensor in backwards you are changing the flow of air over the sensor and making the computer think a different amount of air is coming in. Start by installing the MAF the correct way. Then use brake parts cleaner and spray around the intake gaskets, vacuum hoses, air intake system (after the MAF sensor) and listen for the idle to change. If it races up or dies down then you have found the spot where the unmetered air …
