Feb 24, 2012· 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 variety …
Apr 29, 2020· 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 …
Apr 28, 2019· Video 3 as Monkey Wrench Mike tries to get a Mercedes CLK320 back on the road! This time he tries a new MAF sensor? Are they all created equal?
SOURCE: car will not start when hi there, when air flow unplugged, ecu goes into limp home mode ,a back up if something dies whilst driving. it sounds as if your used mass air flow sensor is faulty , they are more fragile than they look, one knock and these early fine wire models are gone. i replaced many when i worked at a volvo dealership a few years ago. hope this helps, …
Jan 24, 2020· ), I also cleaned out my MAF (Mass Air Flow) Sensor with MAF cleaner, and cleaned out my throttle body with CARB cleaner, and last but not least I ran a can of Sea Foam Engine Cleaner through the throttle body intake. There''s a known issue with the throttle body for this car. I think there''a another post in the forums along with a service bulletin.
Jan 15, 2016· The mass airflow sensor records the amount of air that is coming into the engine and will then calculate how much fuel is needed to offset it. Without a properly working mass airflow sensor, it will be nearly impossible to keep your car running as intended. There are a number of things that can prohibit a mass air flow from working.
The mass airflow sensor is the component used for detecting the flow of air that is entering the engine of a car. The airflow sensor collects details to determine the amount of needed fuel. After collecting the information, the details will be sent to the Engine Control Unit. The ECU will then deliver the required amount of fuel to the engine.
Aug 06, 2019· The mass airflow sensor (commonly abbreviated to MAF) is one of the most important engine management sensors. A bad mass airflow sensor can leave your GMC Terrain’s engine running rough, or even inoperable.. A MAF sensor measures the density of the air entering the intake manifold.
p0102 is your Mass Air Flow device. p0113 is "air intake temperature" sensor voltage too high. You can pretty much ignore your p0113, p0171 may be caused by a bad MAF, and p0300 may be caused by your p0171. the actual indication for your MAF is that the voltage getting to the computer from the MAF is too low.
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.
Feb 22, 2021· 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.
