12/03/2020· /5 (3,225 Views . 45 Votes) As a result, a bad mass air flow sensor causes various driveability problems, including a no-start, stalling, lack of power and poor acceleration. A problem with the air flow sensor could also alter the shifting pattern …
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.
08/08/2012· MAF sensors – fitting and diagnosis issues. Date: August 08, 2012. in: Technical. Function and operation The main function of the Mass Air Flow (MAF) sensor is to measure the volume of air passing through it, and therefore into the combustion chamber of the engine. This measurement allows the ECU to perform adjustments which ensure that the engine is performing to an optimum …
17/12/2002· Re: Air flow sensor cleaning. My V6 had an idle speed that 'hunted' from about 500 ( almost stalling) to 1500rpm when started from cold. It took ages to settle down. Removing the air inlet and watching the air flow sensor made it obvious that this was the cluprit. Yesterday I cleaned the air flow sensor (the whole unit, not just the little ...
22/02/2021· 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.

Anyone who owns a Porsche knows what it means to drive in real luxury and efficiency. When things suddenly take a turn for the worse, and your Porsche winds up in the shop, it can be a tough pill to swallow. Being without a Porsche after ...
Mass air flow sensor. I have replaced my MAF sensor three times in the last seven months, as recently as two weeks ago. Each time it would go about one week before my check engine and slip indicator light would return with a p0101 code and the car would go into “limp” mode which prevents me from accelerating above 2500 rpm and to idle rough ...
13/01/2020· Question: My mass air flow sensor on an 88 Camaro reads 5-volt reference between signal and ground while running and unplugged, on the ECM side, at idle. Shouldn't the mass air flow sensor dictate the voltage going out to the ECM? While plugged in, there is erratic non-detectable voltage, on/off, on/off. My ground tests good, and I have excellent battery voltage on ECM side of the …
24/02/2015· How to troubleshoot a MAF sensor – a technician’s checklist. 1. Check the connector for a correct fit and good contact. 2. Check the mass air flow sensor for damage. 3. Check the measuring elements for damage. 4. Check the voltage supply with the ignition switched on (circuit diagram for pin assignment is necessary).
13/10/2005· Most of us remember the "good old days" when an engine’s air/fuel (a/f) ratio was controlled by a mechanically operated carburetor. Due to the inherent design limitations of mechanical systems, however, carburetors don't respond efficiently to changes …
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.

22/09/2008· Indeed it wasn't the mass air flow sensor. The explanation given to me was that the MAF's were going bad, because of something "burning" them up. I asked them about the Idle Control Valve (ICV) and they said something about "an idle control motor malfunctioning" which was causing problems with the MAF. I couldn't discern if they meant internally in the MAF - like the wire or sensor, or ...
06/06/2018· For instance, one sensor that drivers experience issues with over time is the intake air temperature sensor, also known as the IAT sensor, as well as many other terms depending on the manufacturer. Since the IAT sensor commonly fails over time and can cause significant performance problems, we thought our drivers should know about it.
