Denso 198-0002 Manifold Absolute Pressure Sensor

Denso MAP Sensor for Subaru Applications

Denso Manifold Absolute Pressure Sensor 198-0002 is built for precise intake manifold pressure measurement in Subaru Legacy, Outback, Tribeca, and B9 Tribeca applications. This OE-style sensor supports accurate fuel injection control and cleaner engine operation with a compact design and simplified connections.

Key Features

• Manifold Absolute Pressure Sensor for emission control systems
• Pin terminal type with 1 female oval connector
• 3 male terminals for direct electrical connection
• Compact, lightweight sensor design
• High detection accuracy for precise pressure signal input
• Helps support more accurate fuel delivery and lower emissions

Product Details

Denso 198-0002 is a MAP sensor engineered to measure manifold pressure and send reliable data to the engine control system. By improving signal accuracy, it helps the ECU manage fuel injection more precisely. The Denso MAP sensor line is known for compact packaging, fewer connection points, and dependable performance in OE replacement service. This part cross-references Standard Ignition AS351 and Wells SU7128 for the same application.

Compatible With Subaru Legacy and Subaru Outback models across multiple years, this sensor is also used on Subaru Tribeca and Subaru B9 Tribeca applications. If you are replacing a failing Subaru MAP sensor, Denso 198-0002 is a direct-fit option for the listed vehicles.

Common Issues This Part May Address

• Erratic idle caused by inaccurate manifold pressure readings
• Hard starting related to incorrect air-fuel calculations
• Reduced fuel economy from poor engine load input
• Check engine light concerns tied to MAP sensor faults
• Rough acceleration or hesitation during throttle changes

Installation Notes and Tips

Verify the connector shape, terminal count, and mounting location before installation. For best results, inspect the wiring harness and intake plumbing for damage, vacuum leaks, or corrosion that could affect sensor readings. Confirm fitment by year, make, and model before ordering, especially on Subaru Legacy, Outback, and Tribeca vehicles.

Quality Assurance

Denso MAP sensors are built with high detection accuracy and a simplified connector design to support reliable signal output and consistent operation in emission control systems.
