The Delphi PS20120 is a standard replacement manifold absolute pressure sensor built for accurate engine load and intake pressure readings. It uses a 5-volt voltage signal, a 3-pin male terminal layout, and an oval black connector for a direct-fit style replacement on select Toyota and Lexus applications.

Key Features

• Manifold Absolute Pressure Sensor for emission control and engine management systems
• 5-volt voltage type sensor with 3 terminals
• Black oval connector with 1 connector and male terminal design
• Bolt-on mount type with black plastic housing
• Standard replacement grade for select Toyota and Lexus vehicles
• Package contents: manifold absolute pressure sensor

Detailed Description

Delphi PS20120 is engineered for vehicles that rely on precise manifold pressure input to help the engine control module calculate load, fueling, and timing. Delphi validates its sensors to OE standards and calibrates them for accurate readings, which supports consistent drivability and helps reduce repeat repairs. This part cross-references Standard Ignition AS689 for the same application. Common fitment includes 2018-2023 Toyota Camry, 2019-2023 Toyota RAV4, and 2018-2023 Lexus LS500, along with additional Toyota and Lexus hybrid and gas models.

What It Helps Address

• Incorrect manifold pressure readings
• Check engine light concerns related to MAP sensor performance
• Rough idle or unstable engine response caused by faulty sensor input
• Fuel trim and drivability issues tied to inaccurate load data
• Sensor replacement needs on select Toyota and Lexus vehicles

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. The PS20120 uses a bolt-on design with a black oval connector and 3 male terminals, so confirm the original sensor matches these details. For fitment, this part is listed for applications such as Fits 2018-2023 Toyota Camry, N/A; Fits 2019-2023 Toyota RAV4, N/A; and Fits 2018-2023 Lexus LS500, N/A.
