Denso 198-0001 Manifold Absolute Pressure Sensor

Denso MAP Sensor for Subaru Applications

The Denso 198-0001 manifold absolute pressure sensor is built for Subaru engines that need accurate intake manifold pressure readings for precise fuel control. It is a direct-fit emission control sensor for select Subaru Impreza, WRX, Forester, Legacy, and Outback applications.

Denso’s MAP sensor line focuses on compact construction, fewer connection points, and high detection accuracy to help maintain reliable engine management and lower emissions. This Denso 198-0001 MAP sensor is a practical OE-style replacement for Subaru vehicles that require stable manifold pressure input.

Key Features

• Manifold Absolute Pressure Sensor for emission control and engine management
• Pin terminal type with 3 terminals for a direct electrical connection
• 1 female oval connector for OE-style fitment
• Compact, lightweight sensor design
• High detection accuracy for consistent pressure signal output
• Designed to support precise fuel injection control

Detailed Product Information

The Denso 198-0001 is engineered as a manifold absolute pressure sensor that measures intake manifold pressure and sends that data to the engine control system. On Subaru Impreza, WRX, Forester, Legacy, and Outback models, accurate MAP sensor input is important for fuel delivery, drivability, and emissions performance. The sensor’s 3-pin layout, oval female connector, and male terminals match the OE-style electrical interface used in the listed applications.

This part cross-references Subaru 22012 AA220 for the same application. If you are replacing a failing Subaru MAP sensor, the Denso 198-0001 provides a direct replacement option for the specified model years, including 2014 Subaru Impreza, 2013-2014 Subaru WRX, 2009-2013 Subaru Forester, 2008-2013 Subaru Impreza, 2005-2012 Subaru Legacy, and 2005-2009 Subaru Outback.

Common Problems This Part Can Address

• Erratic manifold pressure readings
• Rough idle caused by incorrect air-fuel calculations
• Reduced throttle response from inaccurate sensor input
• Check engine light related to MAP sensor performance
• Emissions issues tied to poor fuel injection control

Installation Notes and Tips

Verify connector shape, terminal count, and sensor location before installation. Confirm the vehicle application against the listed Subaru fitment for your exact year and model, including 2014 Subaru Impreza, 2013-2014 Subaru WRX, 2009-2013 Subaru Forester, 2008-2013 Subaru Impreza, 2005-2012 Subaru Legacy, and 2005-2009 Subaru Outback. Clear diagnostic trouble codes after installation and inspect the intake system for vacuum leaks or related faults that can affect MAP sensor readings.

Quality Assurance

Denso manufactures this MAP sensor with a focus on accurate detection, compact packaging, and reliable electrical connection design. The sensor line is developed to support precise fuel injection control and reduced emissions in the listed Subaru applications.
