Manifold Absolute Pressure Sensors
Overview

The manifold absolute pressure (MAP) sensor determines the intake manifold pressure or vacuum. These sensors are a major contributor to fuel injector pulse width and ignition and valve

timing, reporting engine load to the engine’s computer

Purpose

The manifold absolute pressure (MAP) sensor determines the intake manifold pressure or vacuum

Function

  • Sends voltage signal to the ECM which changes with the varying pressure/vacuum within the intake manifold
  • ECM uses signal to determine engine load and ensure proper air/fuel ratio

Position

Intake manifold, throttle body or remote mounted under bonnet

Cause for replacement

  • Check engine lamp illumination
  • Engine hesitation
  • Poor fuel economy
  • Failed emissions test
  • Engine stalling
  • Extended crank time

Anatomy and Construction

The NTK Difference

  • High strength thermoplastic is resistant to temperature, moisture and chemicals
  • Properly sized grommet/o-ring is pre-installed (where applicable)
