Heated Oxygen Sensor (H02S): The sensors are located in the exhaust system. On some
vehicles, one sensor is located up at the exhaust manifold(s) and the
other sensor is located down at the catalytic converter. On other
vehicles, both sensors are located down at the catalytic converter.
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

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.
