Description
Is your Duramax hesitating, running rough, or throwing airflow‑related codes because it can’t measure incoming air accurately? The Walker Mass Air Flow Sensor delivers precise intake airflow data to your ECM, enabling it to balance fuel delivery and combustion correctly. When a MAF sensor fails, your truck may exhibit poor throttle response, reduced fuel economy, a rough idle, or a check engine light. This direct‑fit replacement helps restore smooth power delivery, improved efficiency, and dependable performance, whether you’re cruising the highway or towing heavy loads. Built to meet or exceed OEM specifications, this sensor features high‑quality internal components and a rugged housing designed to handle heat, vibration, and contaminants in the intake tract. It installs as a direct replacement in the air intake path and provides a consistent, accurate signal output for precise engine control. Engineered and tested for long service life, it helps eliminate airflow‑related trouble codes and keeps your Duramax diesel running at its best mile after mile
