On a 2007 Chrysler Pacifica, the oxygen sensors are located in two primary areas: upstream (pre-catalytic converter) and downstream (post-catalytic converter). The upstream sensor is typically found near the exhaust manifold, while the downstream sensor is located further along the exhaust system, after the catalytic converter. Accessing these sensors may require lifting the vehicle for better visibility and reach.
