Locate the mass air flow (MAF) sensor on the air intake. Step 3. Grasp the wire harness that connects the MAF sensor to the power unit in the engine compartment and gently pull it out of the MAF sensor. This will disconnect it. Reconnect the negative battery cable to the battery and close the vehicle''s hood. When you start up your vehicle now, the vehicle''s computer will not look to the MAF sensor to check …
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 engine at idle, the MAF’s PID value should read anywhere from 2 to 7 grams/second (g/s) at idle and rise to between 15 to 25 g/s at 2500 …
29/04/2020· The mass air flow (MAF) sensor, part of your vehicle’s electronic fuel injection system, is responsible for calculating the total amount of air entering the engine. A contaminated or failed mass air flow sensor cannot measure the amount of air flow correctly. This causes the engine computer to miscalculate the amount of injected fuel, causing additional damage to …
09/07/2021· Often mass air flow sensor readings are measured at idle, 1,000 RPM, 2,000 RPM and 3,000 RPM. A contaminated or bad air flow sensor will, in most cases, show lower air flow readings than a known good one.
The mass airflow sensor measures the mass of the air that is entering the vehicle, and sends the information to the car’s computer management system. This system then controls the amount of fuel that is injected into the cylinders, so that the ideal fueltoair ratio is achieved. When the mass airflow sensor stops working, the computer cannot receive information on the air intake, and the fueltoair ratio will …
10/07/2021· Problems with the mass air flow (MAF) sensor causing the code P0171 are fairly common in many vehicles. Sometimes the mass air flow sensor just gets dirty and gives false air flow readings causing the engine to run lean. Cleaning the air flow sensor may help temporarily; the proper repair involves replacing the faulty mass air flow sensor. A mass air flow sensor can be tested with a …
01/02/2013· Air Flow Rate From MAF The airflow rate as measured by the mass air flow sensor. Absolute Throttle Position The absolute throttle position (not the relative or learned) throttle position. Usually above 0% at idle and less than at full throttle. Calculated Load Value Indicates a percentage of peak available torque. Reaches at wide open throttle …
20/07/2009· Yes, a digital multimeter can be used in testing the Mass Air Flow (MAF) sensor. In this article, I am going to briefly explain the three basic multimeter tests that are done to find out if it''s bad or not. Although I''m not going to be going into details about each of the different type types of MAF sensors, I will show you where you can find tutorials to test the MAF sensor for …
07/08/2021· Open the vehicles hood to locate the engine''s mass air flow sensor which is located either at the air filter housing or somewhere in the intake tube. Release the wiring connector to the sensor by pressing down on the safety and pulling the connector away from the sensor. Loosen and remove the mounting screws or clamps. Carefully lift the sensor from the housing while taking note of the …
What is a Mass Air Flow (MAF) sensor? A MAF sensor monitors the temperature and weight of air entering your engine. Your onboard computer needs that information to calculate the right amount of fuel for all engine operating conditions. The sensor works by heating a delicate platinum wire or plate and measuring the current required to keep it at a constant temperature while air blows past it. Over time, …
The mass air flow sensor is a device that measures the amount of air entering the engine and supplies this information to the engine control unit (ECU). The ECU uses this information to calculate engine load, which the ECU uses along with information provided by the oxygen sensor(s) to precisely control the engine’s air / fuel ratio. Engine load measurement is also …

3. Mass Air Flow Sensor A defective MAF sensor can trigger the LIMP MODE. The mass airflow sensor, also known as the MAF sensor, detects the volume and temperature of the air entering the engine. These parameters are very critical for the normal operation of the engine. Dirt buildup on the MAF sensors can prevent them from functioning correctly.
20/07/2009· Yes, a digital multimeter can be used in testing the Mass Air Flow (MAF) sensor.

Although I''m not going to be going into details about each of the different type types of MAF sensors, I will show you where you can find tutorials to test the MAF sensor for Buick, Chevrolet, Ford , GMC, …
01/03/2021· It’s another common symptom of bad mass airflow sensor and it happens when the wire is deformed or there is a damage to the device’s electrical components. The engine runs rich or lean because the sensor frequently sends reports that are either higher or lower than the actual airflow. There is no solution for a damaged sensor but to replace it. The same glitch …
A mass (air) flow sensor (MAF) is a sensor used to determine the mass flow rate of air entering a fuelinjected internal combustion engine.. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density with temperature and pressure. In automotive applications, air density varies with the ambient …
