If you don’t see any you can use a multimeter to test the wiring. Start by inspecting the wiring harness for obvious damage.

MAF Sensor Wiring– Make sure to check around the MAF sensor for opens or shorts.

Without knowing how much air is really getting into the engine, P0102 will be thrown.

Intake Manifold/Vacuum Leak– If there is a leak in the intake manifold, it will be impossible for the MAF sensor to get an accurate reading.

Just make sure you check to make sure it fits your year Impala before purchasing. If you do need one, they are pretty reasonable on Amazon.

The second is that it only takes a few minutes to test it with a multimeter. Here’s a video on how to test one without pulling it. MAF Sensor Failure– While it is very likely that the MAF sensor itself could be the problem, it’s absolutely necessary to test it before you replace it.Here’s a great article on exactly how to clean one from Family Handyman. They can be cleaned, but it’s easy to mess one up, and you don’t want to use a wire brush.

It should be considered a high priority to fix, as the MAF sensor not reading properly can really make an impact on the performance of the vehicle. We will cover exactly what that means and potential fixes for it below. It means the the Mass Air Flow (MAF) circuit is low, and that it is not performing within its specified operating range. P0102 is a very common trouble code in the Chevy Impala.
