ACDelco GM OE Mass Air Flow Sensor Assembly

The ACDelco GM OE Mass Air Flow Sensor Assembly (MAF sensor) is a genuine GM original equipment part. It measures the amount of air entering the engine and sends that data to the engine control module. The module uses it to calculate fuel delivery and keep the air-fuel ratio correct, which supports smooth running, good fuel economy and controlled emissions.

Key Features:

• Genuine GM original equipment design from ACDelco, GM's official parts brand
• Supplied as a complete assembly for direct replacement of the original unit
• Gives the engine control module accurate airflow readings
• Helps restore driveability and fuel efficiency when a worn or contaminated sensor causes problems
• Built to GM specifications for fit, function and reliability

Common signs of a failing mass air flow sensor:

• Check engine light
• Rough idle or hesitation
• Stalling
• Poor fuel economy
• Reduced power

Replacing a faulty sensor with a GM OE mass air flow sensor from ACDelco helps restore the engine's airflow measurement and performance.
