Reprogram for MAP
Some owners of 2008 Buick Allure, LaCrosse and Lucerne vehicles equipped with the 3800 engine (VIN Code 2) may comment that the SES light is on.
Upon inspection with a Tech 2, you may find DTC P0106 (manifold absolute pressure sensor performance).
GM Engineering has developed a new ECM calibration to correct the concern. Reprogram the ECM with the latest calibration. There should be no need to replace the MAP sensor.
