As you look over the engine compartment, you will find your Pontiac air mass meter usually mounted adjacent to the air filter assembly. This device, which is also sometimes referred to as air flow meter, is used to determine the airflow that is being delivered into your vehicle's engine. It does that by sending an electronic signal to your Pontiac's ECU, which then sends the necessary commands to the fuel injectors that regulate the amount of fuel that is delivered to the engine. The ECU also makes adjustment on the air intake system according to the need. When you have one, before you clean the engine compartment of your Pontiac auto unit, make sure that there would be no water or degreaser on or around the Pontiac air mass meter because the latter is easily damaged even by water and lubricant. Another thing is when the vehicle shows poor idling or hesitation on acceleration, you are probably keeping a bad air mass meter. You can check the computer diagnostic codes to determine whether you need a Pontiac air mass meter replacement already or not. Its failure can be attributed to the result of water or dirt particles that enter the intake tube. When it happens, a regular clean-up or replacement of the air filter is necessary.
