On 2007 and earlier BL and 3.6L V6 models, as well as all 6.2L V8 engines, the sensor is located on the left side of the intake manifold, while on 2010 and later 3.0L engines, it is positioned on top of the air filter housing. Begin by disconnecting the electrical connector from the sensor, then remove the sensor mounting fasteners and take out the sensor from the intake manifold or air filter housing. To install, follow the reverse order of removal.
