See if the code comes back. I then got a new fault code, P2102, TAC motor circuit low. Hope this helps. What will help us to test the MAF sensor and find out if it's good or bad is knowing that the more air the engine breathes, the bigger the voltage signal the MAF sensor creates.
The goal is to keep the air/fuel ratio at the optimal level. Because this MAF sensor is a hot-wire type that easily becomes contaminated with dirt and stuff from the air filter not performing its job.

You may be able to find a copy in your local auto parts store or online. No check engine during most of the time that it has been running rough.
You can even check if a particular component is failing even before the engine light comes on.
That there are no ignition system misfires. P0104 - "Mass Air Flow Circuit Intermittent"
Depending on the make and model, your car uses either a hot-wire airflow meter (the most common) or a hot-film type. The engine still runs.
A dead dead battery is usually caused by a faulty battery, bad alternator or circuit or a parasitic draw. Primalis Việt Nam from Vi?t Nam on October 21, 2019: I wanted to clean the air flow sensor in the Ford but can't unplug the sensors electrical connector. Carefully wiggle the connector while pressing on the clip or tab. Shouldn't the mass air flow sensor dictate the voltage going out to the ECM? You may have a problem with the self-cleaning circuit. This article was written by the It Still Works team, copy edited and fact checked through a multi-point auditing system, in efforts to ensure our readers only receive the best information. There could be a problem in the circuit, bad connector or loose wire.
The less air the engine breathes, the smaller the voltage signal the MAF sensor sends the PCM. Even a dirty air filter can cause the MAF sensor to send a faulty signal. Be extra careful when pulling on the connector, they become brittle and easily brake. A tremendous lack of power upon acceleration. Then shut off the engine and continue with the following tests. Question: 1990 Mazda Miata has major take off issues. 2 months ago engine diagnosis showed the MAS was bad and it was replaced with a new quality unit. Connect your meter’s black lead to the ground (-) pin on the sensor connector. Interpreting the Results of Your MAF Sensor Test. Dan Ferrell (author) on October 31, 2019: Not all MAF cleaners will work on the Mitsubishi and other models. Copyright © 2009-2020 Abraham Torres-Arredondo All Rights Reserved. Please help me.
