The mass airflow sensor is always on the air intake tube....it has wires plugged into it and when you look inside it ,it has either 3 or 4 thin strips of metal or a honey comb look,thats want you clean....bty cleaning it usually doesn't help.

Where is the mass airflow sensor located on a 1997 Buick Skylark 2.4 liter


Right off the air box its the first sensor on the vehicle .
The air is sucked through the air filter then goes through the mass air sensor so its in the air duct .
They have a spray can cleaner you have to remove the clamps and connections and remove it .Spray it with the cleaner some times it works .
Its a rather expensive part but its vary important because it is the first sensor that the computer reads to adjust all engine controls .
Also don't through it away you will get a lot for the re core value.

Do you know where the mass airflow sensor is located

How to troubleshoot air fuel mixture problem on 1989 lesabre


If your car has a MAF sensor, it is in the air intake hose between the intake and the air filter.
If the check engine light is on, you would need a scanner to read the computer data coming from the sensors to diagnose the problem.

In my '98 Century I am having serious hesitation while accelerating... Only happens sometimes, but frequency is increasing. When the problem occurs, I will drive for a bit, and when put in park, idle...


P0101 Mass Air Flow, P0300 random misfire, Your problem is the Mass air flow, the P300 is the result of the mass air flow range, Mass air flow is a hot wire sensor they fail when contaiminated, as for the P300 that the engine detecting the condition when the mass airflow range is out, but here is another problem 1998 Buick used a back up its called a map sensor its on the top of intake plenum, make sure its seated and wire connection are there, Now you are going to fix the problem yourself if you ever taken out ,a airfilter and replaced it, then all you need to do is purchase a MAF cleaner mass airflow cleaner or brake cleaner or electrical cleaner clean the inside of your mass airflow you dont have to replace it the code is range performance the hot wire cant clean itself, so someone has to do it

Dose the buick park avenue use a map sensor or a mass air flow sensor. or are they the same thing


They are different types of sensors, but in your car the MAP (manifold absolute pressure) sensor, along with the BAROmetric sensor are used to estimate the required fuel flow through the throttle body injectors. These sensors measure pressures inside and outside the engine to estimate airflow. You do not have a MAF sensor. These are more common in later vehices with mulit-port fuel injection. A MAF sensor actually measures the airflow into the engine using a hot wire anemometer. You are correct in believing the sensors serve the same purpose, that is to calculate the fuel flow required for stoichiametric combustion. The oxygen sensor also feeds back to the computer to further refine the fuel charge by measuring oxygen in the combustion products. If excess oxygen is detected, the fuel charge is increased. This is known as closed-loop operation. Closed loop operation is not started until the engine is at operating temperature. If you have more questions, please let me know. I have pasted the location of the MAP sensor below. The sensor is mounted to the air cleaner, but it has a vacuum hose that leads to the throttle body, which is where the pressure must be measured.

Need to know what MAF means.


MAF stands for mass air flow sensor, this is used to tell the computer how much air is entering the engine, check the air filter,and clean the sensor with CRC mass air flow cleaner, with engine off. hope this helps,let me know Ray
