The sensor is attached to the rear of the upper intake manifold on 1999 through 2005 engines, while on 2006 and later V6 models, it is located at the rear of the engine and connected to the upper intake manifold by a vacuum hose. Notably, 2006 through 2010 four-cylinder engines do not utilize a MAP sensor. To begin, disconnect the cable from the negative battery terminal. Next, disconnect the vacuum hose from the sensor on 2006 and later models. After that, remove the mounting screw(s) and detach the sensor, with installation being the reverse of removal.
