The symptoms of a bad mass air flow sensor include low engine power poor fuel economy an engine that wont start a check engine light on the dash and a gas smell from the exhaust fumes.

. The Test to see if you need to replace the sensor is. Loosen the hose clamp from the air filter housing end of the MAF sensor using a ratchet and socket. With the black multimeter test lead and an appropriate tool probe the wire identified with the letter letter C in the photo.

I just meant that if the resisance across the element does not register that is. Reconnect the electrical connector into the MAF sensor. View the MAF sensor inside to make sure there are no obstructions.

Disconnect the connector of the MAF sensor. The mass air flow sensor is part of the engines intake system and is. A MAF sensor measures the density of the air entering the intake manifold.

Connect the positive probe of a voltmeter onto the pin in the terminal marked SIG and the negative probe to the pin in the GND. If you dont know what a multimeter is check out our handy guide here. A MAF sensor measures the density of the air entering the intake manifold.

A bad mass airflow sensor can leave your Ford Mustangs engine running rough or even inoperable. Think I have narrowed it down to an air leak at the intake manifold but have not pinpointed the exact location. The job of the mass air flow sensor is to keep track of.

Place your multimeter in Volts DC mode. So I put the old one back on. Get a flat or Phillips head screwdriver to pop out the tabs or pieces holding the components.

Open the airbox and undo the clasps or latches on the assembly to reach the air duct present between filter and throttle. The mass airflow sensor commonly abbreviated to MAF is one of the most important engine management sensors. Set the multimeter to 20 volts.

Runs smooth though at higher rpm when MAF is unplugged. We took a new reman MAF Sensor and it did the same thing. Connect the black lead of the multimeter to the ground terminal of the battery or chassis and the red one to.

Use straight-pins to back-probe the terminals marked SIG and GND. Ford S-Max yakub88 Shutterstock The most common signs of bad mass air flow sensor MAF in Ford S-Max are loss of power or slow acceleration engine hesitation or jerking during acceleration erratic idling misfires poor exhaust emission values and sometimes black smoke comes out of the tailpipe. Disconnect the MAF sensor from its electrical connector.

A bad mass airflow sensor can leave your Ford F250s engine running rough or even inoperable. Open the hood on the F-150. The mass airflow sensor commonly abbreviated to MAF is one of the most important engine management sensors.

Connect the red multimeter test lead probe the battery positive terminal. The Mass Air Flow Sensors Power Wire Test. A bad mass air flow sensor is often the likely culprit if your car isnt running as it should.

It passes this information onto your Mustangs ECU. This unit is a 4 pin unit thats mounted under your air intake filter housing and cover. The most common signs of bad mass air flow sensor MAF in Ford F-150 are loss of power or slow acceleration engine hesitation or jerking during acceleration erratic idling misfires poor exhaust emission values and sometimes black smoke comes out of the tailpipe.

In order to test this Mustang Mass Airflow sensor you will need to use a multimeter to read the DC voltage at the wires. It passes this information onto your F250s ECU. If any obstructions are in the MAF sensor or sensor screen remove them.

Open the hood of the car. Open your hood and located the MAF which is circled below. Insert the pin into the back to the connector until it contacts the desired terminal.

The mass air flow sensor is part of. Raise the assembly to get your hands on the sensor and use a light torch for convenience.
