Overtime the factory MAF sensor can fail or accumulate dirt and oil, which can cause running issues or activation of the CEL (Check Engine Light).

If your vehicle is running rough, hesitating after starting, or experiencing poor fuel economy, then you may have a problem with your mass air flow sensor.

The MAF Sensor can be easily located beside the air intake box inside the engine bay.
