This guide will tackle Chevy Mass Air Flow (MAF) sensor problems, common symptoms, and how to replace the MAF sensor on a Chevy. The engine control unit uses data from the MAF sensor to calculate the correct mixture of air and fuel that the engine needs.
· How to Clean Mass Air Flow SensorFORD Vehicles! A dirty Mass Air Flow Sensor can cause your vehicle to run bad and cost you tons of extra money on gas and r...
· A replacement mass air flow sensor can cost anywhere from 20 to 600. Replacing a mass air flow sensor is fairly straight forward, so most of the cost comes from the cost of the part, and not the labor. If you are going to replace the MAF yourself, then I’d always recommend buying an OEM mass air flow sensor.
· FIXD, I installed a cold air intake on my 2009 GMC Sierra 1500 SLE and had the P0101 code come up for the mass air flow sensor malfunction. I remedied all of the problems and my check engine light went away.
· sunliner, air flow will vary idle as the PCM adjusts the TB opening to hold desired RPM, Assuming a constant coolant temp. Varying the engine load by shifting to P/N or in gear, or AC on/off will result in 4 different air flow conditions. The article in illogicTC''s post is …
· 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.
· MAF = Mass Air Flow. The MAF sensor reads the amount of air coming into an engine. This is an alternative to a MAP sensor, as the ECM/PCM can read the actual amount of air coming into the engine instead of density of air measured in load. Some injection systems use both MAF and MAP sensors.
· Cleaning the mass air flow sensor on your , (and some select with a MAF sensor) is not hard at all. In this article, I''ll show you how to do it and more importantly, I''ll shed some light on some important do''s and don''ts when cleaning the MAF sensor on your GM vehicle. This article covers the two major types/styles of MAF sensor.
Flow Meters and Advanced Flowmeter Instrumentation Achieve More Accurate and Repeatable Flow Measurement. Sierra Instruments designs and manufactures highperformance thermal mass flow meters and controllers , immersible thermal mass flowmeters, vortex flow meters and transittime ultrasonic flow meters for nearly every gas, liquid, or steam application.
· sunliner, air flow will vary idle as the PCM adjusts the TB opening to hold desired RPM, Assuming a constant coolant temp. Varying the engine load by shifting to P/N or in gear, or AC on/off will result in 4 different air flow conditions. The article in illogicTC''s post is very good reading.
The air is then mixed with the fuel, and combustion is the result. This is what propels the car. 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.
· GMC Sierra O2 Sensor; Mass Air Flow Sensor– The mass air flow sensor calculates the volume of air entering the engine. If it has gone bad, the air fuel mixture will be off and the P0172 code will show. Bad Fuel Injectors– If you have one or more fuel injectors that have gone bad that can certainly cause the air/fuel mixture to go bad.
sensor locations index. Question: where is the cam position sensor. Answer: From the front of the truck, it is located on the passenger side front of the engine. Just below the valve cover. Number 9 above. GMC envoy can you tell me where is can find coolant below temperature sensor. There is …
· The mass air flow sensor is the first sensor that reads the amount of air coming into the motor at any point of time when the vehicle is running. The mass air meter can usually be found just after the air box. The MAF sensor may also be …

· Toyota mass air flow sensor (MAF). When you press the gas, the throttle opens allowing more air to flow over the hot wire. The passing air cools the wire down. The more air flows over the wire, the more electrical current is needed to keep it hot. …
SOURCE: Mass Air Flow problem. The is in the top of the metal tube between the air filter box and the intake manifold. It will have a wire connected to it and it is held in by 2 screws. This is an easy replacement and should take no more than 5 to 10 minutes, assuming you are taking your time.
· Testing to see if the MAF sensor on your GM equipped car or pickup or SUV is bad or not can easily be done with a multimeter. In this article I''ll show you how to do it in a stepbystep fashion, that will either condemn the mass air flow (MAF) sensor as bad or exonerate it.
· Toyota mass air flow sensor (MAF). When you press the gas, the throttle opens allowing more air to flow over the hot wire. The passing air cools the wire down. The more air flows over the wire, the more electrical current is needed to keep it hot. The electric current is proportional to the amount of air flow.
