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.
This guide will show you how to replace the Mass Air Flow (MAF) sensor on Mercedes Benz. If you get any of these codes P0100, P0101, P0102, P0103 and P0104 you most likely need your MAF replaced. Some of the most common symptoms of a bad Mass Air Flow sensor in Mercedes Benz cars are: Engine dies, stalls soon after you start it.
The first mass airflow sensor was the vane style, with this style the vane opens and closes by the amount of air flow that enters the engine. In the late 1980s it evolved to a hot wire design which is still used today. The present mass airflow sensor is primarily a sensor only component where the housing is no longer removable.
Answer: Most likely, the MAF sensor is bad. Question: My mass air flow sensor on an 88 Camaro reads 5volt reference between signal and ground while running and unplugged, on the ECM side, at idle. Shouldn''t the mass air flow …
The oil sprays for air filters have been traced to problems with the mass air flow sensor. This is generally down to the use of too much oil and improper fitting. We must stress that you should only use a light coating of oil on the air intake side of the filter. It is a good idea to clean the mass air flow sensor periodically anyway.
· The sensor reference voltage and ground must be checked. The mass air flow can be tested with a scan tool that displays the live data. The airflow sensor readings at different rpms ( 1000, 2000, 3000) must be compared to the specifications or to the readings of a known good sensor. Read more about testing a mass air flow sensor.
· 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.
· 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.
· Taking this into account, the output value (Volts or Hz) that the mass airflow sensor will generate, and that you can verify with a multimeter, will be greater at 2500 RPM than at 900 RPM. Another very important thing to know, when testing a mass air flow sensor, is that we don''t need to know the exact voltage value for certain engine RPM.
· 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.
· 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.
· 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.

Removal: Caution – The mass air flow sensor hot wire sensing element and housing are calibrated as a unit and must be serviced as a complete assembly. Do not damage the sensing element or possible failure of the sensor may occur. 1) Disconnect the negative battery cable. To remove the MAF sensor, first disconnect the wire harness plug …
· The MAF (Mass Air Flow) sensor is in charge of keeping track of the amount of air going to your engine. When the sensor gets dirty or clogged, bad things start to happen. You''ll notice a rougher idle at first, but then you''ll start having bigger problems like the engine misfiring.
· |P0103 2012 NISSAN VERSA code description The Mass Air Flow sensor is placed in the stream of intake measures the intake flow rate by measuring a part of the entire intake flow. It consists of a hot film that is supplied with electric current from the Engine Control Module ().The temperature of the hot film is controlled by the ECM a certain amount.
Answer: Most likely, the MAF sensor is bad. Question: My mass air flow sensor on an 88 Camaro reads 5volt 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 nondetectable voltage, on/off ...
· A MAF sensor code. Lean and/or rich code (s). Fuel trim code (s). A tremendous lack of power upon acceleration. Black smoke coming from the tailpipe. Vehicle may idle rough and stall. As stated before, the Mass Air Flow Test is a very easy and simple test but there are a couple of things that have to be done first.
just put new motor in my 96 camaro LT1 and i keep getting these codes no matter what i do p0101 p0107 p0430 p0420. i have replaced the mass air flow sensor, idle air control, throttle positioning sensor, plugs. Cant think of what else could cause this problem. any suggestions would be greatly appre... 02 chevy malibu code P0101
· I have changed my mass air flow sensor twice with OEM parts, reset the code multiple times, put a new KN air filter in and the light still comes with in 3 or so miles. I have a 2017 Titan XD with the Cummins. I did find a skinned wire that looks like a rodent got it but I soldered it back together so it is solid. Please start your own thread.
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.
It is integrated into the Mass Air Flow sensor. The Air charge temperature sensor uses pins 1 and 6 on the MAF connector. The colors are White with a Violet stripe and Brown with a White stripe. Ford F150 Location: In the intake manifold on drivers side by the fuel rail. Ford Explorer IAT Location: Driver side of upper intake manifold.
MAF Sensor Testing The TechAssist Team It’s always a good idea to test a Mass Airflow (MAF) sensor before replacing it. Here is a fast and accurate way to track a MAF’s performance and output to the PCM. Connect a scan tool to see the MAF sensor Parameter Identification Data (PID) information. With the
· A good Mass Air Flow Sensor helps in balancing the airfuel ratio in the engine but Bosch Original Equipment 0280217515 is known to enhance the fuel consumption by up to 20 percent. So, if you want a MAF Sensor that takes care of fuel consumption as well, get this one installed in your vehicle.
How do you reset a mass air flow sensor. When you press the gas, the throttle opens allowing more air to flow over the hot wire. The mass air flow sensor on your nissan d21 pick up has three wires attached to it. The mass airflow sensor measures the volume of air moving through the air intake system. Mass air flow/check engine light.
· 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 …
