Spectra MP178 Manifold Absolute Pressure Sensor

Spectra MP178 Manifold Absolute Pressure Sensor

The Spectra MP178 manifold absolute pressure sensor is built for direct replacement use in emission control systems. It is engineered to meet or exceed OE specifications for fit, form, and function, with a black plastic housing, black connector, and a 3-pin male terminal layout.

Compatible With 2013-2018 Nissan Altima and 2017-2020 Nissan Rogue, this MAP sensor supports accurate intake manifold pressure readings for proper engine management. The Spectra MP178 is a practical OE-style replacement for Nissan Altima and Nissan Rogue applications that require a rectangular, single-port sensor design.

Key Features

• Manifold absolute pressure sensor for emission control and engine management systems
• OE-style fit, form, and function specification
• Black plastic housing with black connector
• 1 rectangular connector with 3 male terminals
• 1-port sensor design
• Direct replacement format for select Nissan applications

Detailed Description

The Spectra MP178 is a manifold absolute pressure sensor designed for vehicles that rely on precise manifold pressure input for fuel and ignition control. Its rectangular connector, male terminal configuration, and single-port layout support a straightforward OE-style replacement on select Nissan models. This part cross-references Delphi PS20116 for the same application. It also cross-references Standard Ignition AS665 for the same application.

Fits 2013-2018 Nissan Altima, N/A. Fits 2017-2020 Nissan Rogue, N/A. The MP178 part number is a useful reference when matching the sensor to the original unit during service on Nissan Altima and Nissan Rogue vehicles.

Common Issues This Sensor May Address

• Incorrect manifold pressure signal to the engine control module
• Rough idle caused by a faulty MAP sensor
• Hard starting related to inaccurate air-load readings
• Reduced drivability from inconsistent sensor output
• Check engine light triggered by MAP sensor faults

Installation Notes and Tips

Verify connector shape, terminal count, and port layout before installation. Confirm the vehicle application against the original sensor part number, including MP178, before replacement. Inspect the connector and wiring for corrosion, bent pins, or damaged terminals so the new sensor can seat and communicate properly with the engine control system.

Quality Assurance

Spectra states that this sensor is engineered to meet or exceed OE specifications for fit, form, and function. That makes the MP178 a direct-fit replacement option for technicians and DIY repairs focused on restoring accurate manifold pressure input.
