Where is the oxygen sensor on 2007 Dodge Caliber?

The oxygen sensor on a 2007 Dodge Caliber is typically located in the exhaust system. There are usually two sensors: one upstream (pre-catalytic converter) and one downstream (post-catalytic converter). The upstream sensor is positioned near the engine, while the downstream sensor is located further along the exhaust pipe, after the catalytic converter. To access them, you may need to lift the vehicle and work underneath it.
