Spectra MP176 Manifold Absolute Pressure Sensor

Manifold Absolute Pressure Sensor Overview

The Spectra MP176 manifold absolute pressure sensor is built to meet or exceed OE specifications for fit, form, and function. It is a direct replacement style sensor for Mazda applications that need accurate intake manifold pressure input for engine management.

Key Features

• OE-spec fit, form, and function for straightforward replacement.
• Black plastic housing with a rectangular connector design.
• 4-pin male terminal layout with a single connector and single port.
• Designed for Mazda 3, Mazda 3 Sport, CX-5, MX-5 Miata, Mazda 6, and CX-3 applications.
• Part number MP176 for easy identification and ordering.

Detailed Description

The Spectra MP176 MAP sensor is engineered as a replacement for vehicles that rely on manifold pressure data to help the engine control system calculate load and adjust fueling and timing. With a black plastic body, one connector, and a 4-terminal male pin configuration, it is built to match the original sensor layout used in the listed Mazda applications. This part number, MP176, is a practical choice when replacing a worn or faulty manifold absolute pressure sensor on a Mazda 3, Mazda CX-5, or Mazda 6.

This part cross-references Standard Ignition AS486 for the same application.

Common Problems It Can Address

• Rough idle caused by inaccurate manifold pressure readings.
• Hard starting or extended cranking related to sensor signal issues.
• Check engine light concerns tied to MAP sensor performance.
• Poor throttle response from incorrect engine load data.
• Fuel trim and drivability problems linked to a failing sensor.

Installation Notes and Tips

Verify connector shape, terminal count, and port layout against the original part before installation. Confirm the vehicle application by year, make, and model, since MP176 is used across multiple Mazda platforms. Inspect the intake connection point and wiring connector for damage or contamination before installing the new sensor.
