Delphi PS20066 Manifold Absolute Pressure Sensor

Delphi PS20066 Manifold Absolute Pressure Sensor

The Delphi PS20066 is a standard replacement manifold absolute pressure sensor built for accurate voltage-based pressure readings. It is engineered for vehicles that rely on precise intake manifold pressure data to support engine management, including Toyota Tacoma, Toyota Tundra, Toyota 4Runner, Toyota Sequoia, Lexus GX470, Lexus LX470, and Toyota Land Cruiser applications.

Key Features

• Manifold Absolute Pressure Sensor for emission control and engine management systems
• Voltage-type sensor with a 3-terminal, pin-style connection
• 1 connector, rectangular shape, male connector and terminal design
• Bolt-on mount with 1 port for straightforward OE-style replacement
• Black plastic housing and black connector color
• OE-standard testing and calibration for accurate readings
• Maximum pressure reading: 2.0 / 22.0

Detailed Description

Delphi PS20066 is a MAP sensor designed as a standard replacement part for a wide range of Toyota and Lexus vehicles. Delphi validates and calibrates its sensors to OE standards, helping ensure the sensor reports manifold pressure accurately to the engine control system. That accuracy matters for fuel delivery, ignition timing, and overall drivability on applications such as the Toyota Tacoma, Toyota Tundra, and Toyota 4Runner. This part cross-references DENSO Auto Parts 198-1003 for the same application.

What It Helps Address

• Erratic idle caused by incorrect manifold pressure readings
• Hesitation or poor throttle response during acceleration
• Check engine light related to MAP sensor performance
• Rough running from inaccurate engine load input
• Fuel mixture issues tied to faulty pressure signal data

Installation Notes

Verify connector style, terminal count, and bolt-on mounting before installation. This sensor uses a single rectangular male connector with 3 terminals and a black housing, so matching the OE connector and port layout is important. Confirm vehicle application by year and model before ordering; this part is listed for 2004-2023 Toyota and Lexus applications, including 2005-2023 Toyota Tacoma and 2004-2009 Toyota 4Runner.

Quality Assurance

Delphi backs this sensor with OE development and product validation methods. Each unit is tested and calibrated to OE standards to support accurate signal output and reduce repeat repairs.
