Walker 225-1103 Manifold Absolute Pressure Sensor

Walker Sensor Only MAP Sensor 225-1103

Walker 225-1103 is a manifold absolute pressure sensor built as an OE replacement for precise intake manifold pressure measurement. It sends pressure data to the ECM so fuel delivery and ignition timing can be adjusted for stable drivability, fuel economy, and emissions control.

The Sensor Only line from Walker focuses on direct-fit replacement sensors engineered for electrical output, pressure range, and connector fit that match OE requirements. This Walker MAP sensor is a practical choice for 1998-2001 Chevrolet Metro and 1998-2001 Suzuki Swift applications when restoring engine management performance.

Key Features

• Manifold Absolute Pressure (MAP) sensor for engine load calculation
• OE replacement design for direct integration with the factory system
• Black plastic housing with oval female connector
• 3 blade terminals, plug-in fitting, 1-port design
• Built for high engine bay temperatures, vibration, and intake air exposure
• Walker 225-1103 cross-references Standard Ignition AS102 for the same application

Product Details

Walker Products MAP sensors measure pressure inside the intake manifold and report that signal to the ECM. On vehicles such as the Chevrolet Metro and Suzuki Swift, accurate MAP sensor input helps the engine computer manage load calculations, fuel injection, and spark timing. The result is consistent throttle response and emissions-system operation when the original sensor is no longer reading correctly. Part number 225-1103 is engineered to meet OE expectations for fit and signal output, making it a direct replacement for select 1998-2001 Chevrolet Metro and 1998-2001 Suzuki Swift models.

Common Issues This Part Can Address

• Check engine light related to MAP sensor performance
• Rough idle or unstable engine speed
• Hesitation during acceleration
• Poor fuel economy from incorrect load readings
• Driveability problems caused by inaccurate manifold pressure data

Installation Notes

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. Confirm the vehicle application by year, make, and model before replacing the original unit on a Chevrolet Metro or Suzuki Swift.

Quality Assurance

Walker Products engineers 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 dependable engine management performance.
