Delphi AF10703 Mass Air Flow Sensor MAF Sensor

The Delphi AF10703 is a direct-fit, all-new mass air flow (MAF) sensor engineered to OE specifications. As a critical component in your engine management system, the MAF sensor continuously measures the volume and velocity of air entering the engine and transmits that data to the engine control module (ECM), which uses it to precisely schedule fuel injection and maintain an optimal air-fuel ratio — resulting in better fuel economy, reduced emissions, and consistent drivability.

Key Features:

• All-new construction — never remanufactured; built with calibrated, all-new components free from debris or contamination
• OE-grade sensing elements — delivers highly accurate airflow readings across a wide range of ambient temperatures, down to -50°C cold sealing
• Dual heated elements — Delphi is the only manufacturer offering dual heated elements, allowing integration into any air/fuel system regardless of ducting assembly
• Fast response time — typically less than 15 milliseconds to 90% of flow change for precise, real-time ECM communication
• Multiple sensing elements — eliminates sensitivity to supply voltage fluctuations and power ground line noise
• Probe-style design (where applicable) — reduces repair time by eliminating the need to replace the entire flow tube
• Tested and calibrated to OE standards using highly accurate OE equipment to ensure accurate readings and reduce comebacks
• Packaged in a protective clamshell and includes a driver bit and screws for installation

A failed MAF sensor commonly causes sluggish performance, rough idling, stalling, or increased fuel consumption. The Delphi AF10703 restores precise air measurement and is backed by Delphi's decades of OE sensor manufacturing expertise.
