#17 of 17 O2 sensor location late model Sable/Taurus by rogerb34 Aug 23, 2009 (10:57 am)
Upstream sensors are critical as they are primary in fuel injection timing. Downstream sensors verify that emissions are within tolerance. Upstream sensors are located on the front and rear exhaust manifolds where the cylinders converge. Looks like a large spark plug but is aluminum with 4 wires and a connector. The rear bank same but not easy to see. Disconnect the front bank sensor first. Squeeze to release catch. Do it with left hand. Takes some tries to unplug. Reason left hand is the rear bank connector is accessible left hand unless removal of the upper air intake manifold. I've done it on a 05 Duratec without removal. Use a 1/2 inch O2 sensor socket and rachet. Inexpensive deep socket with wire slot at auto store. Try cold w/o using max force. If it doesn't break, warm engine for 30 sec and apply a penetrant. Rear use a penetrant soaked sponge. High mileage engines can pose a removal problem. I've replaced several without a problem but. Add a little anti sieze to the new sensor threads. Make sure not on the tip. Snug tight like a spark plug and connect the plug. Bosch is my preference and OEM electrical connection. O2 sensor is primary for proper fuel and MPG. Those cars with Upstream sensors have a cat built into the exhaust pipe just below the sensor. Drive with a check engine warning light on due to fuel mixture beyond specs will burn out the cat. Extremely expensive to replace the upstream cat as it is cast into the exhaust pipe. In comparison, the upstream sensors are $50 - $80 each depending on the car.
