Delphi AF10538 Mass Air Flow Sensor MAF Probe

The Delphi AF10538 is a direct-fit, all-new mass air flow (MAF) sensor probe engineered to deliver the same accurate airflow readings as the original equipment part. As a probe-only replacement, it targets the component that fails the vast majority of the time, eliminating the unnecessary cost and waste of replacing the entire flow tube housing.

How It Works:

A mass air flow sensor — also commonly called an air meter — measures the volume and velocity of air entering the engine's intake system and transmits that data to the engine control module (ECM). The ECM uses this signal to precisely calculate fuel injection timing and duration, maintaining an optimal air-fuel ratio for improved fuel economy, reduced emissions, and responsive drivability.

Key Features:

• Always new, never remanufactured — built with all-new calibrated components, not cleaned or refurbished cores
• OE-calibrated performance — tested and calibrated using highly accurate OE equipment to match original specifications
• Probe-only design — replaces just the failed electronics, reducing repair time and eliminating unnecessary parts replacement
• Fast response time — typically less than 15 milliseconds to 90% of flow change for accurate, real-time ECM communication
• Wide temperature range — high-quality sensing elements deliver consistent performance across a broad range of ambient temperatures
• Dual heated elements — allows integration into virtually any air/fuel system regardless of ducting assembly configuration
• Includes hardware — ships with a driver bit and installation screws for a straightforward install
• Protective packaging — delivered in a plastic clamshell sealed with a factory sticker to protect sensitive sensing elements in transit

Delphi has been a manufacturer of OE mass air flow sensors since their introduction over 30 years ago. Every AF10538 sensor is designed and tested to meet or exceed OE requirements, ensuring reliable, comeback-free performance.
