Delphi AF10777 Mass Air Flow Sensor

Overview

Delphi AF10777 is a specific-fit mass air flow sensor built as a complete assembly with a gasket or seal included. It uses a 5.0-volt, 4-terminal design with a rectangular connector and bolt-on mounting for a direct replacement approach.

Compatible With Nissan Altima, Rogue, Sentra, Pathfinder, and Infiniti QX50, QX55, and QX60 applications, this Delphi AF10777 sensor is engineered to meet or exceed OE requirements using all-new components. It is not remanufactured and is built for consistent airflow signal accuracy in supported applications.

Key Features

• Specific-fit mass air flow sensor for confirmed vehicle applications
• Complete assembly with gasket or seal included
• 5.0-volt sensor with 4 terminals and a rectangular connector
• Bolt-on mounting with 2 mounting holes
• Standard replacement grade with premium item grade
• Delphi AF10777 part number for easy identification

Detailed Description

The Delphi AF10777 mass air flow sensor is built for vehicles that require a direct-fit replacement sensor with OE-style electrical and mounting characteristics. Its pin-style terminals, male connector, and bolt-on design support a clean installation in the listed Nissan and Infiniti applications, while the included seal helps complete the assembly. Delphi manufactures this sensor with calibrated, all-new components and tests it to meet or exceed OE requirements. The AF10777 is a practical choice for restoring accurate airflow measurement on a Nissan Altima, Rogue, or Sentra, as well as supported Infiniti QX50, QX55, and QX60 models. This part cross-references Standard Ignition MAS0508 for the same application.

What It Is Used For

• Restoring accurate mass airflow signal output
• Addressing drivability issues tied to incorrect air metering
• Replacing a worn or failed OE-style sensor assembly
• Correcting sensor-related fault codes in supported applications
• Improving engine management response when the original sensor is no longer reliable

Installation Notes

Verify connector shape, terminal count, and mounting style before installation. The Delphi AF10777 uses a bolt-on design with a rectangular connector, 4 terminals, and a gasket or seal included. Confirm vehicle application by year, make, and model before ordering, and compare the existing sensor to the part number AF10777 for proper fitment.

Quality Assurance

Delphi states that this mass air flow sensor is manufactured with calibrated, all-new components and is designed and tested to meet or exceed OE requirements. The AF10777 is not remanufactured.
