Walker 225-1329 Manifold Absolute Pressure Sensor

Walker Sensor Only MAP Sensor 225-1329

Walker 225-1329 is a manifold absolute pressure sensor built as an OE replacement for vehicles that rely on accurate intake manifold pressure data for engine control. It communicates pressure readings to the ECM so fuel delivery and ignition timing can be adjusted for proper drivability, fuel economy, and emissions performance.

The Sensor Only line from Walker focuses on direct-fit replacement sensors engineered to match OE electrical output, pressure range, and connector fit. For Acura Integra, MDX, RDX, and TLX, as well as Honda Civic, CR-V, and Accord applications, this MAP sensor supports precise engine load calculation in modern gasoline and diesel management systems.

Key Features

• OE replacement manifold absolute pressure sensor
• Measures intake manifold pressure and sends data to the ECM
• Engineered to OE specifications for output, range, and connector fit
• Black plastic body with oblong female connector
• 3-terminal male spade design with 1 connector
• Built for high engine bay temperatures, vibration, and intake air contaminants
• Walker part number 225-1329 for direct replacement searches

Detailed Description

Walker Products 225-1329 is designed for vehicles that depend on accurate MAP sensor input to calculate engine load. By reporting manifold pressure to the ECM, the sensor helps the engine management system maintain correct air-fuel control and ignition timing. This makes it a practical replacement when restoring factory drivability on a Honda Civic or Honda CR-V, or on Acura models such as the RDX and TLX.

This Walker Sensor Only MAP sensor is built to match OE-style connector geometry and electrical characteristics for straightforward integration with the existing harness. The black plastic housing, oblong connector shape, and 3-terminal layout support a direct-fit replacement approach for the listed applications. Part number 225-1329 also cross-references Standard Ignition AS636 for the same application.

What It Helps Fix

• Check engine light related to MAP sensor performance
• Rough idle or unstable engine operation
• Hesitation during acceleration
• Poor fuel economy caused by incorrect load calculation
• Emissions performance issues tied to inaccurate manifold pressure readings

Installation Notes and Tips

Verify connector shape, terminal count, and sensor style before installation. This is a sensor-only replacement, so confirm the existing mounting location and harness connection on the vehicle before ordering. Clear diagnostic trouble codes after installation and confirm that live data readings respond normally during engine start and throttle changes.
