The front/upper upstream sensor (1/1) is located in the exhaust downspout equal before the front mini-catalytic convertor.

The front/lower downstream sensor (1/2) is located in the exhaust downpipe just after the front mini-catalytic convertor, and before the main catalytic convertor.2. Second you must purchase your oxygen sensor either from a native automotive parts store or online. I recommend BOSCH oxygen sensors. All four oxygen sensors located in the Jeep Grand Cherokee are different prices and sizes. While you are purchasing your oxygen sensor, ask the store clerk or look online for an oxygen sensor socket. It has a split down the middle for the cable to fit.
3. Third, use the picture above for specific location on the oxygen sensor you need to replace. Use the socket to remove the bad oxygen sensor and replace it with the new one.
