In 2014, the Jeep Patriot is equipped with two oxygen sensors that serve distinct purposes. The upstream and downstream oxygen sensors perform specific functions, making them non-interchangeable components. One sensor is located under the hood, just past the exhaust manifold, while the other can be found beneath the vehicle on the exhaust pipe near the catalytic converter. Although replacing oxygen sensors is a straightforward and cost-effective task, neglecting to do so when necessary can result in catalytic converter failure – and that's definitely not good. If the catalytic converter fails, you could be facing a repair bill of over a thousand dollars, making knowledge of the oxygen sensor locations crucial.
