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.
Feb 22, 2021· The mass airflow sensor is a key sensor in your car. Your car has a lot of sensors, and this is just one that helps your car run properly. That brings up the question of can your car run without the mass air flow sensor? In this article, we will look at what happens when you disconnect the mass airflow sensor.
This formula takes mass flow per unit time and converts it to mass flow per cylinder. The 15 is a constant which corresponds to the characteristics of a V8 running a 4cycle combustion cycle. The easiest thing to do is to load the log file into excel (export it as a CSV), then create a formula in excel which applies the formula above.

Jul 09, 2021· Low mass air flow readings do not mean the sensor is bad. A clogged up air filter or plugged catalytic converter can also cause lower air flow sensor readings. Vacuum leaks affect air flow sensor readings too. That''s why mechanics use a knowngood sensor to compare the readings. Read more: Vacuum leaks: common sources, symptoms, repairs.
Aug 06, 2019· A bad mass airflow sensor can leave your Chevy Tahoe’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 Tahoe’s ECU. The ECU uses this information along with other sensor data to control the amount of fuel that enters the combustion chamber.
Mar 12, 2020· He traced it down to my Mass Air Flow sensor, cleaning it didn''t help, replacing was the only fix. I would try a Bluedriver and do a full system scan, it may find a bad sensor. Also try an ABS scan, it may find a bad wheel sensor. How cold is it by you, this issue does come up more in colder weather and what year is it?
Oct 01, 2016· The stock mass airflow sensor is designed for stock tuning (air and fuel flow) and will not automatically recalibrate for additional air flow. Upgraded intakes can lose power with newer cars because most use MAFbased fueling. With a change of pipe size, the fueling is affected, and the factory ECU is calibrated to the stock size.
Jan 31, 2021· The cruise control uses some of the same sensor inputs the transmission uses and can indeed affect the transmission and cruise control. If the transmission is slipping then the cruise control may not control the speed steady. ... The mass air flow sensor attached to your car’s engine is designed to sense the amount of air coming into the air ...
The most obvious difference is the lack of mass air flow (MAF) sensor in the 9092 setups. Instead, a manifold absolute pressure (MAP) sensor is used to measure engine load (basically, engine vacuum). Likewise, the 8589 setups do not use a MAP sensor. These used a mass air flow sensor to calculate air being drawn into the engine.
Oct 30, 2017· If your car did not have cruise control from the factory, you will need this kit for a massair conversion in addition to the conversion harness or massair kit. The VSS sensor used for the factory cruise control systems is also required for a massair system.
Aug 06, 2019· A bad mass airflow sensor can leave your Chevy Cruze’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 Cruze’s ECU. The ECU uses this information along with other sensor data to control the amount of fuel that enters the combustion chamber.
Jul 26, 2010· check engine light is on. starts flashing at above 55mph using a/c or cruise control. dealership says need to replace catalytic converter and mass air flow sensor. Can the failure of the mass air flow sensor cause the catalytic converter to need replacement? Is 1400 reasonable for these repair works?
The electronic throttle relies on an APP sensor and a TPS sensor. A problem with either one of these will cause this. Also, the cruise would be affected by this, as there is no cruise servo, it''s controlled be the electronic throttle body. Posted on Oct 19, 2008 Anonymous 783 Answers SOURCE: 98 explorer studders between 45and 50mph
Apr 22, 2008· To answer directly, yes. A bad MAF sensor can affect a computercontrolled transmission if the transmission control computer uses the MAF signal to determine shift points.
Feb 27, 2010· 2001 V70 Mass Air Flow (MAF) Sensor Cleaning... Help, Advice, ... but I noticed that the car has some very rare subtle/slight hesitations while engaged to the cruise control (not trying to think about the ole ETM debacle on this model; I still have a white sticker with the updated download).
For example, if the cruise control is inhibited or disabled, work through flowcharts P28, P30 and P27. Following the flowcharts in the sequence identified will help rectify any concerns while ... Substitute the mass air flow sensor and monitor the voltage on the data logger as above. Did this cure the problem? END NO YES P19 Cont.
Mass Air Flow Sensors ( MAF Sensors) are precision components that measure the amount of airflow entering the intake manifold and must communicate clearly with the Engine Control Module (ECM). Remanufactured MAF sensors with debris from prior use can hinder this communication and cause the vehicle to experience drivability issues.

One way to check to see if a mass air flow sensor has gone bad is by tapping on the engine when it''s running to see if it stumbles. Find out how to remove a ...
One common engine code Volkswagen owners get is P0101. Whether it is a gas or diesel, the cause is the mass air flow (MAF) sensor, which measures the amount of air flowing into the engine. The sensor is likely overly sensitive. If the sensor detects the flow is more than 18% out of spec, it will trigger the engine light.
