What does the a MAF sensor do on a GMC traverse?
A MAF sensor measures the density of the air entering the intake manifold. It passes this information onto your Traverse’s ECU. The ECU uses this information along with other sensor data to control the amount of fuel that enters the combustion chamber.
Can a bad mass airflow sensor cause a Chevy Traverse to run rough?
A bad mass airflow sensor can leave your Chevy Traverse’s engine running rough, or even inoperable. A MAF sensor measures the density of the air entering the intake manifold.
Why does my GMC traverse run rich when idling?
Idle Issues – Your Traverse may run rich or lean when idling, or it may also idle erratically. A rich condition is when there is not enough air relative to the fuel in the air/fuel mixture. The exhaust color is usually darker when running rich.
What is a normal MAF reading?
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 rpm, depending on engine size. Most manufacturers provide specifications for air flow at idle; some will provide specifications at several engine speeds.

How is MAF measured?
The Mass Air Flow (MAF) sensor measures the amount of passing air going through the air intake system. The sensor measures the amount of passing air with a resistive platinum wire that is placed in the air stream of the air intake system.
Does MAF sensor increase horsepower?
The performance mass airflow sensor replaces your OEM sensor and improves on mileage and can increase horsepower by 13. This performance MAF sensor increases airflow by up to 45% and low-end torque. The power flow sensor is a huge upgrade from the stock unit, and it works great with all factory electronics.
What should I do after replacing MAF sensor?
Therefore we would like to give some advise on what to do, when the new MAF does not work....After Installation of the new MAF:But if the motor continues to have problems, run the engine idle for 20-30 minutes.You can reset the ECU by disconnecting the battery for 10 min.More items...•
How long does it take for a mass air flow sensor?
5-90 minutesTime Required: 5-90 minutes, depending on how easy or difficult it is to reach and remove the mass air flow sensor on your particular vehicle. Tools & Materials: Air intake cleaner. Screwdrivers, wrenches, and whatever else is needed to access the mass air flow sensor on your particular vehicle.
Are all MAF sensors the same?
There are two common types of mass airflow sensors in use on automotive engines. These are the vane meter and the hot wire. Neither design employs technology that measures air mass directly. However, with additional sensors and inputs, an engine's ECU can determine the mass flow rate of intake air.
How do you diagnose a MAF sensor?
Symptoms of a Faulty Mass Air Flow SensorThe engine is very hard to start or turn over.The engine stalls shortly after starting.The engine hesitates or drags while under load or idle.Hesitation and jerking during acceleration.The engine hiccups.Excessively rich or lean idling.
What should happen if I unplug MAF sensor?
Q: Car runs with the mass airflow sensor unplugged. If you plug it in it will die if the car is running. If you unplug the mass air flow sensor the car will start. If you try to plug it in while it's running the car will die.
What brand MAF sensor is best?
Best Air Flow SensorDelphi Mass Air Flow Sensor. Delphi AF10043 Mass Air Flow Sensor. ... Denso Mass Air Flow Sensor. Denso 197-6030 Mass Air Flow Sensor. ... GM Genuine Parts Mass Air Flow Sensor. ... Hitachi Mass Air Flow Sensor. ... JDMON Mass Air flow Sensor.
Can I upgrade my MAF sensor?
If you've already modded your engine to increase air flow, you should upgrade your MAF. Your stock unit is probably not equipped to gauge a bigger volume of air, and this will entirely throw off its signals.
How do you calibrate a MAF sensor?
MAF Calibration 101Step 1 - Health Check. ... Step 2 - Cleaning the MAF Sensor. ... Step 3 - Clear the Fuel Trims. ... Step 4 - Drive the Car. ... Step 5 – Analyze the Logs. ... Step 6 – Modify the MAF table in VersaTuner. ... Step 7 – Flash the Modified MAF Table.
What happens when MAF sensor malfunctions in Chevy Traverse?
If the MAF sensor is defective or dirty, it does not send correct measured values to the control unit of Traverse. The optimal amount of fuel can no longer be calculated which results in either too little or too much fuel injected into the combustion chambers. The engine runs too “lean” or too “rich”.
What causes MAF sensor to fail in Traverse?
The most common cause of a malfunctioning MAF sensor in Chevy Traverse is dirt and grime accumulation on the sensor. Air filters are effective at cleaning the air to a certain extent. When the vehicle is running, dirt and other airborne particles that escape from the air filter can settle on the sensor.
How to check if the MAF sensor is bad in Chevy Traverse?
Reading out the fault codes using a diagnostic device is relatively reliable. If you see P0100, P0101, P0102, P0103 or P0104 code in the OBD2 scanner, it indicates a problem with the mass air flow sensor. However, it can happen that there are no error codes. In case of doubt, the sensor may have to be replaced.
Cleaning dirty MAF sensor in Chevy Traverse
Cleaning the mass air flow sensor can help the sensor measure the correct values again, but only if the erroneous readings are caused by dirt accumulation. However, caution is advised here, as the sensor parts are very sensitive to touch.
Use OBD2 scanner for diagnosis
Since Chevy Traverse is equipped with on-board diagnostics (OBD), a fault diagnosis can provide initial indications of where the malfunction is located.
Conclusion
There are many reasons why MAF sensor is malfunctioning in your Chevy Traverse. When looking for the reason, you should always start with the most obvious cause, dirty MAF sensor that only needs cleaning.

What does a bad mass airflow sensor do on a Chevy Traverse?
A bad mass airflow sensor can leave your Chevy Traverse’s engine running rough, or even inoperable. A MAF sensor measures the density of the air entering the intake manifold. It passes this information onto your Traverse’s ECU.
How to tell if MAF sensor is bad?
Here are the most common symptoms of a bad or failing MAF sensor: Idle Issues – Your Traverse may run rich or lean when idling, or it may also idle erratically. A rich condition is when there is not enough air relative to the fuel in the air/fuel mixture. The exhaust color is usually darker when running rich.
How to clean a MAF sensor?
Cleaning the Mass Airflow Sensor 1 Locate the MAF Sensor – It’ll be in between the air filter and the throttle body. 2 Remove the Sensor- Take care not to damage the wiring harness or the connector pins that receive the harness in the MAF. Simple hand tools will be all that you need to complete the job. 3 Clean the Sensor – Now that you’ve removed your Traverse’s MAF sensor, it’s time to clean it. You’ll need the MAF cleaner. You are not scrubbing anything. Let the chemicals do their job. About a dozen small bursts will be all that you need. 4 Replace the Sensor
What happens if a MAF sensor goes bad?
