Keep the engine's air metering accurate with the Hitachi Astemo Mass Air Flow Sensor (MAF0129), a New unit that measures the amount and characteristics of air entering the engine so the ECM can trim fueling. It's a direct-fit replacement for the 2016-2025 Chevrolet Malibu [L4-1.5L], 2018-2022 Chevrolet Equinox [L4-1.5L], and 2018-2022 GMC Terrain [L4-1.5L].

Hitachi builds these sensors with precision elements and quality components, and each one is 100% air-flow tested and calibrated for its application to help the vehicle meet the manufacturer's emission standards.

  • New, OE-approved unit: a genuine Hitachi air flow sensor built to the OE performance and durability standards for this application.
  • Welded connections: connections are welded instead of soldered for dependable electrical continuity.
  • Contaminant bypass port (where applicable): designed to support reliable operation and longevity.
  • 8-pin terminal: eight pin-type terminals. Wiring harness and housing are not included.

If a failed mass air flow sensor is the cause of a rough idle, hesitation, or an airflow-related check engine code, this sensor replaces it. Diagnose the cause before replacing. Country of origin: Japan.
