· 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.
What You Need to Troubleshoot Your MAF Sensor. Whatever your sensor type, general troubleshooting steps remain basically the same. A basic digital multimeter (DMM) with at least 10 Megohms of impedance (to protect circuits and your car''s computer) will help you test your MAF sensor.

· i have a 2008 duramax. i tow alot of heavy loads. lately, if i get on the gas hard it is very sluggish. truck wont raise much over 2000 rpm, is very slow, the reduced engine power comes up and check engine light. i took it by orileys and they put computer on it, says its mass air flow sensor. i...
· Chevy Silverado P0102: MAF Sensor – Circuit Low. P0102 is a very common trouble code in the Chevy Silverado. It means the the Mass Air Flow (MAF) circuit is low, and that it is not performing within its specified operating range. We will cover exactly what that means and potential fixes for it below. It should be considered a high priority to ...
How to repair P0103 Chevrolet code Mass or Volume Air Flow Circuit High Input. The Mass Air Flow (MAF) sensor measures the amount of air ingested by the engine. The direct measurement of the air entering the engine is more accurate ...
Qualified mechanics look for any damages in the electrical connector, sensor, wiring, air cleaner, loose hose clamps, intake or vacuum hoses, and repair or replace the MAF. If there are no visible problems, then the mechanic will conduct a circuit test using a multimeter with a digital display to get the sampling rate and sensor range readings to determine whether the output of the MAF sensor ...
· The mass air flow sensor (MAF) has become a standard part on most engine applications and is mounted in the intake air stream just past the air filter. It measures the amount of air (volume) in the intake flow by way of a thin wire mounted in the air stream. This wire is heated by the MAF with a precalculated voltage/current value.
· 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.
If the degree of air flow or sensor voltage varies by more than a preprogrammed amount, a code P010F will be stored and a malfunction indicator lamp may be illuminated. Code Severity Symptoms The likelihood that major drivability and fuel efficiency issues will accompany a code P010F is great, therefore it should be addressed with a certain degree of urgency.

· If the air mass is measured in grams, then the calculated amount of fuel will also be in grams. Using an average density of gasoline of pounds per gallon and knowing that there are 454 grams per pound, then dividing the total fuel mass in grams by (454 * ) yields the total number of gallons of fuel burned for a given amount of air (as measured by the MAF sensor).
· |P0101 CHEVROLET code description The Mass Air Flow (MAF) sensor measures the amount of air ingested by the engine. The direct measurement of the air entering the engine is more accurate than calculating the airflow from the Manifold Absulte Pressure (MAP), the Intake Air Temperature (IAT), and the engine speed (speed/density).
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 …
· The IAT 2 is integrated into the mass air flow sensor assembly. It is the second air temperature sensor in the air stream. The engine control module (ECM) supplies 5 V to the signal circuit, and a ground for the low reference circuit. The ECM monitors the IAT sensor 2 signal for an excessively high or low voltage.
