Delphi AF10237 Mass Air Flow Sensor Probe OE Replacement MAF

The Delphi AF10237 is a new (not remanufactured) mass air flow sensor probe engineered to deliver the same precise airflow measurements as the original equipment part. Also known as an air meter or MAF sensor, this sensor measures the volume and density of air entering the engine and transmits that data to the engine control module (ECM/ECU).

The ECM uses this signal to precisely schedule fuel injection and maintain an optimal air-fuel ratio, directly impacting engine performance, fuel economy, and emissions output. A failed or contaminated MAF sensor can cause rough idling, sluggish performance, stalling, increased fuel consumption, and an illuminated check engine light.

Key Features:

• 100% new construction — no remanufactured or reconditioned components
• Probe-only design — replaces only the failed sensing element, eliminating the need to replace the entire housing assembly
• OE-calibrated and tested — all units tested to OE specifications using OE-grade equipment for accurate airflow readings
• High-quality sensing elements — engineered for consistent performance across a wide range of ambient temperatures
• Direct OE replacement — matches original fit, form, and function; 4-terminal blade-type connector, bolt-on mounting
• Protective packaging — ships in a plastic clamshell to protect sensitive sensing elements from damage prior to installation
