Walker 225-1574 Manifold Absolute Pressure Sensor

Walker MAP Sensor for Genesis Applications

Walker Products Part Number 225-1574 is a manifold absolute pressure sensor built as an OE replacement for modern engine management systems. It measures intake manifold pressure and sends that data to the ECM so fuel delivery and ignition timing can be adjusted for accurate engine load control.

Compatible With 2021-2026 Genesis G80, 2023-2026 Genesis G90, 2022-2026 Genesis GV70, 2021-2026 Genesis GV80, and 2025-2026 Genesis GV80 Coupe, this Walker Sensor Only MAP sensor supports direct-fit service on gasoline and diesel platforms where the listed application calls for a plug-in, 3-terminal sensor.

Key Features

• OE replacement manifold absolute pressure sensor for engine load measurement
• Black plastic housing with oval female connector
• 1 connector, 3 blade terminals, plug-in fitting type
• Built for accurate electrical output, pressure range, and connector fit
• Engine bay durability for heat, vibration, and intake air exposure
• Walker 225-1574 for direct replacement service on listed Genesis models

Detailed Product Overview

Walker Sensor Only focuses on replacement sensors that match OE-style fit and signal behavior. This MAP sensor is engineered to communicate manifold pressure data to the ECM, helping the engine management system calculate load and maintain proper fuel injection and ignition timing. The result is stable drivability and emissions control when the original sensor is no longer performing correctly. Part number 225-1574 is specified for Genesis G80, G90, GV70, GV80, and GV80 Coupe applications listed above.

Common Issues This Sensor Can Address

• Check engine light related to manifold pressure sensor performance
• Rough idle or inconsistent throttle response
• Incorrect fuel trim or load calculation concerns
• Reduced power output caused by inaccurate manifold pressure data
• Emissions performance issues tied to faulty sensor readings

Installation Notes and Tips

Verify connector shape, terminal count, and port layout before installation. This sensor uses a black oval female connector with 3 male blade terminals and a plug-in fitment, so the replacement should match the vehicle’s original electrical connection and mounting style. Confirm the vehicle year and model against the listed fitment for Genesis G80, G90, GV70, GV80, or GV80 Coupe before service. Walker 225-1574 is a sensor-only replacement.

Quality Assurance

Walker Products manufactures this MAP sensor to OE specifications for electrical output, pressure range, and connector fit. Each unit is tested for accuracy, responsiveness, and long-term reliability to support consistent engine control performance in the listed Genesis applications.
