How to replace a mass airflow sensor in a car?
In most vehicle models, all you have to do is: 1 Disconnect the part of the air intake duct that connects to the MAF sensor. 2 Carefully unplug the sensor electrical connector. 3 Unscrew two or more sensor mounting bolts. 4 Remove the old sensor. 5 Install the new one.
Can a bad MAF sensor cause engine problems?
More frequent stops at the gas station You get diagnostic trouble codes pointing to the MAF sensor On some vehicle models, the MAF sensor also informs the computer about air intake temperature and engine load (to control some automatic transmission functions). So a bad MAF sensor on these cars can cause an even wider range of symptoms.
What should the voltage be on a MAF sensor?
Depending on your MAF sensor, your voltage reading should be between 0.60 to 0.80 volts at idle. If your reading indicates 12 volts or pretty close to it, you are probing the power wire, not the signal wire).
How does a bad MAP sensor affect the car?
However, if the sensor calculates depressed load in the engine then, it automatically affects all the further functioning of the engine. For more, if PCM record low engine load then, it would surely reduce the fuel injection into the cylinders of the engine. By this, the engine won’t remain powerful enough to give the desired output.

When to use MIL illumination for Kia throttle relearn?
Recheck for DTC (s). If the engine is started without waiting for at least five seconds after turning the ignition key to the on position to allow the ECM to automatically learn the throttle valve position, MIL illumination with DTC P0638 and P2110 will occur. In this case, repeat the above procedure.
What should the MAF sensor reading be on my car?
Your meter should read between 10 and 13 volts, close to battery voltage. If not, you may have a fault in that part of the circuit between the electrical connector and the car computer. Turn off the ignition key. MAF sensor cleaning. Photo courtesy of Wapster on Flickr.
What should the air flow sensor read on my car?
Turn the ignition key to the ON position, but don’t start the engine. Your meter should read between 10 and 13 volts, close to battery voltage. If not, you may have a fault in that part of the circuit between the electrical connector and the car computer.

Is there a sectioning procedure available for Kia?
Does Kia have a sectioning procedure available? Does Kia have part replacement procedures available? Is there a sectioning procedure available for the trunk floor? Is there a sectioning procedure available for the front lower rails? Is there a sectioning procedure available for the apron?
Your meter should read between 10 and 13 volts, close to battery voltage. If not, you may have a fault in that part of the circuit between the electrical connector and the car computer. Turn off the ignition key. MAF sensor cleaning. Photo courtesy of Wapster on Flickr.
How does the MAF tell the throttle plate position?
Depending upon the location of the throttle plate’s edge, the electrical resistance through the sensor strip tells the computer the exact throttle plate position. Minor adjustments to this position are made by the MAF, which senses temperature and humidity.
Why does the idle go up after cleaning the throttle body?
The idle is going to be high at first until the computer relearns the idle again. Cleaning the throttle body allowed more air to enter the engine, and the computer is compensating by adding more fuel.
Can a bad MAF sensor cause a bad transmission?
You may have a bad MAF sensor if you notice one or more of the following symptoms: On some vehicle models, the MAF sensor also informs the computer about air intake temperature and engine load (to control some automatic transmission functions). So a bad MAF sensor on these cars can cause an even wider range of symptoms.
What happens when a mass air flow sensor goes bad?
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 faulty MAF sensor can cause your vehicle to run too rich or run too lean.
What do you need to know about a throttle position sensor?
What Is a Throttle Position Sensor? This vital sensor allows your engine to maintain a proper amount of air. This feature is dependent on the throttle valve. When you press down on the gas pedal, your throttle body unit’s valve opens.
Depending upon the location of the throttle plate’s edge, the electrical resistance through the sensor strip tells the computer the exact throttle plate position. Minor adjustments to this position are made by the MAF, which senses temperature and humidity.
Where is the MAF sensor on my car?
You may also notice you’re filling up at the gas station more than usual. MAF sensors are located between the air filter and the throttle body and are responsible for measuring the amount of air entering the engine. Most vehicles have a hot wire MAF sensor. It has one heated wire and one ambient temperature wire.
