Position of MAF? Does it matter? | Chevy Trailblazer SS Forum


Oct 29, 2008· Technically, clocking the MAF incorrectly can affect the output of the sensor. But it has a lot to do with the intake ducting design. If the MAF has a relatively straight duct in front of it as well as behind it (as it should be), you wouldn''t skew the sensor output as much. If there is a turn or an elbow immediately in front or behind the MAF ...

Flow change due to a 90 bend | Physics Forums


Oct 10, 2009· Anyway, it doesn''t really matter. There''s no loss of volume (or mass flow) going through the 90. There''s only a pressure drop. Nature has this rule called "conservation of mass" which means that you can''t destroy or create mass. All the oil that goes through the 7/16" galley has to go through the 3/8" galley as well. No mass loss.

What Does the Mass Airflow Sensor Do? | YourMechanic …


Nov 17, 2015· How often does the mass airflow sensor need to be replaced? Mass airflow sensors (MAF) have no expiration date. They are not included on the manufacturer’s scheduled maintenance list of things to replace based on mileage, like spark plugs or filters. They can remain in service indefinitely as long as they continue to function correctly.

Upside down Mass Air??????? | StangNet


Jun 26, 2006· I built a custom bracket to mount the mass air sensor on my 66 conversion. A friend of mine saw it and told me that you must mount the sensor with the plug up. I can make a new bracket without a whole lot of trouble, but I like the way it looks now. Can you mount the sensor in any direction...

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.

What are the Mass Air Flow sensor problems? : Isuzu Rodeo ...


Mass air flow sensor problems Problems mass air flow sensors are very common. The MAF sensor could get contaminated or damaged. Often this happens when an old or improperly installed air filter allows some unfiltered air into the engine or when oil from an oilsoaked air filter contaminates the air flow sensor.

Measuring Air Flow


Apr 24, 2015· The air flow sensor is located directly in the intake air stream, between the air cleaner and throttle body where it can measure incoming air. (hot wire automotive mass air flow sensor) Primary components of a Hot Wire MAF sensor are a thermistor, a platinum hot wire, and an electronic control circuit.

How to Install Mass Airflow Sensors Know Your Parts


The mass airflow sensor on your vehicle is used to read the amount of airflow entering the engine. The engine then takes this information and uses it to create the proper air fuel mixture so your vehicle runs properly. Here we have a variety of mass airflow sensors. You have probably seen one of these designs on your vehicle.

Simple Air Flow Detector Circuit Diagram


Sep 05, 2017· This circuit is a visual indication of airflow. We can detect the air presence or air flow by using this circuit. The main component of this air flow sensor circuit is bulb filament which is responsible for creating variation in voltage when there is airflow. Bulb filament has the negative temperature coefficient and because of that its filament resistance change inversely …

Which way does the mass airflow sensor go?


May 27, 2020· Which way does the mass airflow sensor go? Note that the MAF sensor may have an air flow direction arrow (usually located on top of the MAF sensor). The MAF sensor must be mounted with the arrow pointing towards the throttle body. Click to see full answer. In this way, can a mass air flow sensor be installed backwards?

Why Would A Car Run Better With The Mass Air Flow Sensor ...


How To Unplug The Mass AirFlow Sensor. Plugging out this sensor is the only way to disable it. There is no switch or anything. It needs to be physically disconnected. Fortunately for you, I have created a short stepbystep procedure, which is relatively the same for all vehicles. Signs Of A Faulty Air Flow Sensor
