Walker 225-1563 Manifold Absolute Pressure Sensor

OE Replacement MAP Sensor for Hyundai and Kia

Walker 225-1563 is a manifold absolute pressure sensor built for OE replacement use on select Hyundai and Kia applications. It measures intake manifold pressure and sends that signal to the ECM so the engine can calculate load, adjust fuel delivery, and set ignition timing with the correct response.

With a black oval female connector, 4 blade terminals, and a plug-in fitment, this Walker Sensor Only MAP sensor is built for direct electrical and connector compatibility on the listed vehicles. It is a practical replacement for drivability concerns tied to inaccurate manifold pressure readings.

Key Features

• Manifold Absolute Pressure sensor for engine management systems
• OE replacement design for electrical output, pressure range, and connector fit
• Black oval connector with 1 connector, 4 terminals, and female terminal gender
• Plug-in installation style with plastic body construction
• Built for gasoline and diesel engine management environments
• Walker 225-1563 for select Hyundai and Kia fitments

Product Details

Walker Products Sensor Only MAP sensors are engineered to restore accurate manifold pressure feedback to the ECM. That signal is used to calculate engine load and support fuel injection and ignition timing control, which affects power delivery, fuel economy, and emissions performance. This part number, 225-1563, is listed for 2020-2026 Hyundai Sonata, 2021-2026 Hyundai Elantra, 2022-2026 Hyundai Kona, 2022-2026 Hyundai Santa Cruz, 2022-2026 Hyundai Tucson, 2021-2023 Hyundai Santa Fe, 2021-2024 Kia Sorento, 2023-2024 Kia Sportage, and 2023-2024 Kia Niro.

This part cross-references Hyundai/Kia OE number 393002S000 for the same application.

Common Uses

• Check engine light related to MAP sensor signal faults
• Rough idle or unstable engine load readings
• Hesitation, poor throttle response, or drivability complaints
• Incorrect fuel trim behavior caused by inaccurate manifold pressure data
• Emissions performance issues tied to sensor output errors

Installation Notes

Verify connector shape, terminal count, and vehicle application before installation. This Walker MAP sensor uses a plug-in connection with a female oval connector and 4 blade terminals, so the existing harness should match the listed configuration. Confirm the vehicle year, make, and model against the fitment data for the exact application.

Quality Assurance

Walker MAP sensors are built to OE specifications for electrical output, pressure range, and connector fit, then tested for accuracy, responsiveness, and long-term reliability. The design is intended to withstand engine bay heat, vibration, and intake air contaminants while maintaining consistent signal performance.
