Walker 225-1392 Manifold Absolute Pressure Sensor

Walker MAP Sensor for Honda and Acura

Walker Products Part Number 225-1392 is a sensor-only manifold absolute pressure sensor built for OE replacement use. It measures intake manifold pressure and sends that data to the ECM so the engine can calculate load, fuel delivery, and ignition timing with the correct inputs.

Compatible With 2017-2021 Honda Civic, N/A; 2023-2025 Honda Civic, N/A; and 2024-2025 Acura Integra, N/A. This Walker MAP sensor is also cross-referenced to Bosch 0261230435 for the same application.

Key Features

• Manifold Absolute Pressure (MAP) sensor for engine management
• OE replacement design for electrical output, pressure range, and connector fit
• Black plastic body with oval female connector
• 4 blade terminals, plug-in fitting, 1 port
• Built for high engine-bay temperatures, vibration, and intake air contaminants
• Walker Part Number 225-1392 for direct catalog lookup

Product Details

Walker Sensor Only MAP sensors are engineered to restore accurate manifold pressure readings for gasoline and diesel engine control systems. On Honda Civic and Acura Integra applications, the sensor helps the ECM maintain proper fuel injection and ignition timing by reporting real-time intake manifold pressure. The result is stable drivability data for the engine control strategy, with connector and output characteristics matched to OE specifications. Part number 225-1392 is a practical replacement choice when the original sensor is failing or sending incorrect pressure signals.

Common Issues This Part Can Address

• Check engine light related to MAP sensor performance
• Rough idle or inconsistent throttle response
• Incorrect fuel trim or load calculation
• Hesitation during acceleration
• Reduced fuel economy caused by inaccurate manifold pressure readings

Installation Notes

Verify connector shape, terminal count, and port layout before installation. This sensor uses a plug-in, female oval connector with 4 blade terminals and a single port, so matching the OE-style electrical connection is important for proper operation. Confirm vehicle application by year and model before ordering, especially for 2017-2021 Honda Civic, 2023-2025 Honda Civic, and 2024-2025 Acura Integra.

Quality Assurance

Walker Products designs this MAP sensor to meet OE specifications for fit, electrical output, and pressure range. Each unit is tested for accuracy, responsiveness, and long-term reliability to support consistent engine management performance.
