Where is the oxygen sensor on a 2006 jeep Cherokee?

On a 2006 Jeep Cherokee, the oxygen sensor is typically located in the exhaust system. There are usually two sensors: one before the catalytic converter (upstream) and one after it (downstream). The upstream sensor is generally found on the exhaust manifold or just after it, while the downstream sensor is located further along the exhaust pipe, near the catalytic converter. For precise location, it's best to refer to the vehicle's service manual or consult a mechanic.
