Hi.

The pressure sensors are located in the exhaust system. Most vehicles have two or more sensors per tail pipe.One sensor is located before the cat converter, on the engine side, and one sensor is located after the cat converter.
The sensor looks like a conic-shaped objecct protruding from the exhaust pipe.

The sensor is removed unscrewing it and pulling it out. Before removing the sensor, disconnect the wire connecting sensor to PCM wiring.

If the sensor does not come out, try heating the exhaust pipe with a blow-torch. Follow all safety prescription during the operation.

O2 sensors are classified with Bank and Sensor number, if you want to locate a determined sensor, refer to this article: O2 sensor location

Best regards.

Ginko.

  • Park the Expedition in a safe and level surface. Set the transmission to the neutral position.Open the hood, lift the front of the vehicle using a floor jack and safely support it on jack stands.Starting at the exhaust manifold at either side of the engine, follow the exhaust pipe down. Right before the pipe connects to the catalytic converter, you will see the first heated oxygen sensor threaded on to the exhaust pipe. And right after the catalytic converter, you will find the other sensor. Both exhaust pipes are configured the same way; depending on your engine model, you might have two or four of these sensors installed. Whatever sensor or sensors you need to replace, follow this same procedure.Unplug the electrical connector of the oxygen sensor you need to change. Do not pull the wires to unplug the sensor, always grab the plastic connector.Remove the sensor using a ratchet and an oxygen sensor socket.Compare the old sensor with the new one and make sure they match up.Apply a light coat of anti-seize compound to the threads of the new sensor and install it by hand first.Tighten the sensor using the ratchet and sensor socket, but do not over tighten or the sensor and threads may be damaged.Plug the oxygen sensor electrical connector. If you need to replace any one of the other sensors, follow steps 4 through 8; then lower

    Follow the exhaust pipe from the manifold and you will find your sensors sticking out at 90 degs from the pipe, follow the wire and disconnect from the terminal. you will need a ring spanner or special socket normally about a 22mm ( varies from sensors to sensor ) and unscrew anti clockwise, then just fit new in reverse order

    How to Replace an Oxygen Sensor
    Parts:
    1. Oxygen Sensor
    2. Oxygen Sensor

    Tools:
    1. 3/8 in. Drive Ratchet
    2. Multimeter
    3. Oxygen Sensor Socket
    4. Combination Wrench Set
    5. Crimp Tool
    6. Socket Set
    7. Scan Tool

    Steps:
    Step 1 * Park the vehicle on a level surface. Set the parking brake and open the hood.
    o Tip: Safety Tip:Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or safety shoes.
    o Tip: Always make sure the struts on the hood can fully support the weight of the hood so that it does not close on you while working. The use of a hood prop can securely hold it in place.

    Step 2 * With the engine off and cool, locate the defective oxygen sensor in the exhaust manifold or pipe. If necessary, lift the front of the vehicle and support it with jack stands.
    o Tip: Most vehicles have multiple oxygen sensors. How many sensors, depends on the model year and type of engine.

    Step 3 * Disconnect the wire connector at the defective oxygen sensor.

    Step 4 * Remove the oxygen sensor from the exhaust system.

    Step 5 * If you are installing a universal oxygen sensor, cut off the connector from the original sensor and splice the connector wires to the new oxygen sensor. Follow the manufacturer’s instructions supplied with the sensor.

    Step 6 * For threaded oxygen sensors, apply anti-seize compound to the threads and install the new sensor.

    Step 7 * For flange mounted oxygen sensors, install a new gasket and tighten the mounting bolts.

    Step 8 * Reattach the wire connector from the sensor.

    Step 9 * If necessary, connect the OBD I/II scanner and erase the fault code.

    Hope help with this (remember rated and commented this help) Good luck.
