Delphi PS20071 Manifold Absolute Pressure Sensor

Delphi PS20071 MAP Sensor Overview

Delphi PS20071 is a manifold absolute pressure sensor built for accurate voltage-based pressure readings in emission control systems. It is a standard replacement MAP sensor with a 3-pin male terminal design, bolt-on mounting, and a single rectangular connector for a direct-fit style service replacement.

Compatible With Nissan Altima, Sentra, Rogue, 370Z and select INFINITI applications, this Delphi MAP sensor supports OE-style calibration and consistent signal output. The PS20071 part number is also referenced in cross applications where the same sensor design is specified.

Detailed Description

Delphi PS20071 is engineered as a manifold absolute pressure sensor for vehicles that rely on precise intake manifold pressure data for fuel and engine control. Delphi validates and calibrates its sensors to OE standards, helping maintain accurate readings and stable system performance. The PS20071 uses a black plastic housing, a single rectangular connector, and a 3-terminal male interface for straightforward replacement in the correct application.

This part fits 2019-2023 Nissan Altima, 2020-2022 Nissan Sentra, 2021 Nissan Rogue, 2009-2020 Nissan 370Z, 2014-2019 INFINITI QX80, 2014-2018 INFINITI Q70, 2015-2018 INFINITI Q70L, 2014-2017 INFINITI Q50, 2014-2017 INFINITI QX50, 2014-2017 INFINITI QX70, 2015 INFINITI Q40, 2014-2015 INFINITI Q60, and 2011-2013 INFINITI QX56. This part cross-references Hitachi Automotive PRS0002 for the same application.

What It Helps Address

• Incorrect manifold pressure signal readings
• Driveability concerns tied to MAP sensor output
• Engine control issues caused by a failing pressure sensor
• Emission control faults related to intake pressure data
• Replacement needs for worn or damaged OE-style MAP sensors

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. Confirm the vehicle application by year, make, and model, since the PS20071 is used across multiple Nissan and INFINITI platforms. Inspect the port and electrical connection for contamination or damage before installing the new sensor.

Quality Assurance

Delphi sensors are developed and validated using OE-level methods, with testing and calibration performed to support accurate readings and consistent replacement performance. That process helps reduce repeat repairs when the correct application is selected.
