What is the purpose of the Manifold Absolute Pressure (MAP) sensor for Chevrolet Colorado and GMC Canyon?

The Manifold Absolute Pressure (MAP) sensor is a device for monitoring the pressure variations in the intake manifold that occur due to changes in engine load and speed and then converting this into voltage. The PCM gets its information as a varied voltage signal from closed throttle (high vacuum) to wide open throttle (low vacuum). The PCM utilizes the MAP sensor in controlling fuel delivery as well as ignition timing. To swap the MAP sensor, start by disconnecting its electrical connector. This can be achieved by unplugging the electrical connector of map sensor, squeezing together the retainer tabs and removing it, then pulling up on the sensor until it comes out vertically from its mounting flange on top of intake manifold. Thereafter, inwardly squeeze retainer tabs of the sensor so as to detach it from manifold's mounting flange. At last, raise straightaway sensor for detaching it away. Finally, put everything back where you found it during removal.
