Cardone 74-7539 Mass Air Flow Sensor

Remanufactured MAF Sensor for Buick and Oldsmobile

Cardone 74-7539 is a remanufactured mass air flow sensor built to restore accurate airflow feedback to the engine control system. It is engineered to track original equipment output curves and maintain tight tolerances for reliable scan tool readings and smooth vehicle performance.

The Cardone Mass Air Flow Sensor line focuses on OE-style fit and electrical consistency. This remanufactured approach includes full re-soldering of critical components to improve connection quality and reduce intermittent electrical faults in daily driving conditions.

Key Features

• Remanufactured OE-style mass air flow sensor for precise airflow measurement
• Tracks original equipment output curves for accurate engine management feedback
• 100% re-soldering of critical components for stronger electrical connections
• Automated computer testing for functionality and reliability
• Plastic black housing with bolt-on mounting and 2 mounting holes
• Includes sensor and instruction sheet
• Earth-friendly remanufacturing process reduces raw material and energy use versus new part production

Detailed Description

Cardone 74-7539 is a remanufactured Mass Air Flow Sensor for select Buick Century and Oldsmobile Cutlass Ciera, Cutlass Cruiser, and 98 applications. It is built to maintain the output curve and tolerance levels expected by the engine control system, helping the vehicle read incoming air correctly and maintain stable operation. This part cross-references Buick and Oldsmobile OE numbers 25007539 and 25007872 for the same application.

Fits 1985-1988 Buick Century, N/A. Fits 1985-1988 Oldsmobile Cutlass Ciera, N/A. Fits 1987-1988 Oldsmobile Cutlass Cruiser, N/A. Fits 1985 Oldsmobile 98, N/A, with WF4 Drivability Option.

What It Helps Solve

• Hesitation during acceleration
• Stalling or rough idle conditions
• Poor fuel economy caused by incorrect airflow readings
• Poor engine performance and drivability issues
• Intermittent sensor operation from worn electrical connections

Installation Notes and Tips

Before installing Cardone 74-7539, inspect the air filter, intake ducts, connectors, and wiring for dirt, debris, cracks, looseness, or moisture intrusion. Check for over-voltage sources, shorted wiring, and air intake obstructions, since these conditions can damage the replacement sensor. If the original unit showed signs of burnt components, cracked boards, or intermittent operation, verify the root cause has been corrected before installation.

Quality Assurance

Each sensor is tested with automated computer equipment to confirm function and reliability, and on-car validation routines are used to verify form, fit, durability, and performance requirements. The remanufacturing process is designed to meet OE-style specifications while reducing material and energy use.
