the mass air flow sensor is located under the top plastic engine cover. to remove this un screw the oil filler tube by hand and remove the top cover. its just to the right of center engine. unplug this sensor. next it has two screws to take this off. It is not standard screws so look at it. remove them and replace sensor. After install go to autozone and have the warning code removed. This is done free. 2000 buick lesabre

SOURCE: Mass Air Flow problem
The M.A.S. is in the top of the metal tube between the air filter box and the intake manifold. It will have a wire connected to it and it is held in by 2 screws. This is an easy replacement and should take no more than 5 to 10 minutes, assuming you are taking your time.

yes your right. it is a low circuit input code for a mass air flow sensor. you can try taking the mass air off and cleaning it good. sometimes it will help but normally they are just bad.

It is inline with the air intake .They are typically held in the tubing with hose clamps and a 2 or 3 wire connection. Make sure you check for direction of air flow.
