Denso MAP Sensor for Toyota and Lexus
Denso 198-1002 is a manifold absolute pressure sensor built for precise intake manifold pressure measurement in select Toyota and Lexus applications. It uses compact sensing technology with a simplified connection design to support accurate fuel injection control, reliable signal output, and lower emissions.
Key Features
- Manifold Absolute Pressure Sensor for emission control systems
- Pin terminal type with 1 rectangular female connector
- 4 male terminals for OE-style electrical connection
- Compact, lightweight sensor design
- High detection accuracy for precise fuel delivery control
- Designed to reduce connection complexity and improve reliability
- OE cross-reference: Toyota/Lexus 89421-47010
Product Details
The Denso Manifold Absolute Pressure Sensor, part number 198-1002, measures manifold pressure so the engine control system can calculate load and adjust fuel injection more accurately. This sensor line is engineered for direct-fit service on select Lexus GX460, LC500h, LS500h, RX450h, RX450hL, GS450h, CT200h and Toyota Highlander, Prius, Prius C, Prius V, Prius Plug-In, Tundra, and Sequoia applications. If you are replacing a Toyota MAP sensor or Lexus MAP sensor, 198-1002 is an OE-style option built around the original connector and terminal layout.
Denso’s MAP sensor design focuses on accurate detection, compact packaging, and fewer connection points to support stable operation in emission control systems. This helps the engine management system respond to changing intake conditions with better precision. Part number 198-1002 also cross-references Toyota/Lexus 89421-47010 for the same application.
What It Helps Address
- Check engine light related to manifold pressure signal faults
- Rough idle caused by inaccurate intake load readings
- Hard starting or poor throttle response from incorrect fuel calculation
- Elevated emissions from unstable air-fuel control
- Driveability issues tied to a failing MAP sensor
Installation Notes and Tips
Verify connector shape, terminal count, and OE part number before installation. This sensor uses a rectangular female connector with 4 male terminals, so the harness should match the original configuration. Confirm the vehicle application by year, make, and model before replacing the sensor, especially on Toyota Prius, Tundra, and Lexus RX450h platforms.
Quality Assurance
Denso manufactures this MAP sensor to OE-level specifications for accurate signal detection and dependable operation in emission control service. The compact design and reduced connection count are intended to support long-term reliability in the original vehicle application.
