O2 sensor how to change it out


There is a special socket with a slot. I don't have one so I use an open end wrench. If that doesn't work, I use a vice grip. If you have line wrenches, those are best next to the special tool. Do you know which one you're going for? Here is the procedure from autozone.com:


REMOVAL & INSTALLATION WARNING
The oxygen sensors each use a permanently attached pigtail and connector. This pigtail should not be removed from the oxygen sensor. Damage or removal of the pigtail or connector could affect proper operation of the oxygen sensor.
NOTE Take care when handling an oxygen sensor. The in-line electrical connector and louvered end must be kept free of grease, dirt or other contaminants. Avoid using cleaning solvents of any type. DO NOT drop or roughly handle any oxygen sensor. GM says, "A dropped sensor is a bad sensor." A special anti-seize compound is used on the oxygen sensor threads. The compound consists of graphite suspended in fluid and glass beads. The graphite will burn away, but the glass beads will remain, hopefully making the sensor easier to remove. New or service sensors will already have the compound applied to the threads. If a sensor is removed from an engine and if for any reason is to be reinstalled, the threads must have anti-seize compound applied before reinstallation.

WARNING The heated oxygen sensor may be difficult to remove when the engine temperature is less than 120°F. Excessive force may damage the threads in the exhaust manifold or the exhaust pipe.

  1. Disconnect the negative battery cable.
  2. Raise and safely support the vehicle.
  3. If working on the HO2S 1, remove the intermediate exhaust pipe and the heat shield.
9a007ee.gif

Fig. Note this special socket with a cutaway slot to accommodate the oxygen sensor's wire harness (pigtail)

  1. Detach the electrical connector and carefully remove the oxygen sensor. Because the permanently attached pigtail may be difficult to work around, note that there are special wrench sockets made with the side removed to accommodate the pigtail.
To install:
  1. Coat the threads of the oxygen sensor with a suitable anti-seize compound, if necessary.
  2. Install the sensor and torque to 30 ft. lbs. (41 Nm).
  3. Install the remainder of the components in the reverse order of removal.
  4. Connect the negative battery cable.

Where is the O2 sensor located on the 2003 V6 All Wheel Santa Fe and how dificult is it to replace?


Hyundai Santa Fe 2001-05
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
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.

REPLACING OXYGEN SENSORS


    Remove the Oxygen Sensor
  1. Step 1 Start the engine and let it idle for four minutes to raise the exhaust system temperature. This will make removal of the oxygen sensor much easier and prevent damage to threads on the exhaust pipe.
  2. Step 2 Turn off the engine.
  3. Step 3 Detach the ground battery cable using a wrench.
  4. Step 4 Locate the oxygen sensor or sensors you need to replace. The sensors are threaded into the exhaust pipes before and after the catalytic converter. The oxygen sensor has a cylindrical body and the approximate size of a spark plugmag-glass_10x10.gif.
  5. Step 5 Raise the front of your vehicle using a floor jack and support it on two jack stands. This will help you gain access to the sensor or sensors if necessary. If you need to work under the vehicle, wear safety goggles.
  6. Step 6 Unplug the sensor electrical connector.
  7. Step 7 Unscrew the oxygen sensor using a box-end wrench or a ratchet and oxygen sensor socket.
  8. Step 8 Remove the sensor or sensors from the vehicle.
  9. Install the New Oxygen Sensor
  10. Step 1 Apply a light coat of electrically conductive anti-seize compound to the threads of the new oxygen sensor.
  11. Step 2 Thread the oxygen sensor into the exhaust pipe by hand first.
  12. Step 3 Finish tightening the sensor using the box-end wrench or ratchet and oxygen sensor socket.
  13. Step 4 Plug the sensor electrical connector.
  14. Step 5 Lower the vehicle.
  15. Step 6 Attach the ground, battery cable using the wren

O2 Sensor on a 1996 Cadillac Eldorado


Hello mrsalbert, my name is JShreader. Thank you for choosing fixya.com

Depending on which oxygen sensor you are looking for...there are several of them throughout the Exhaust System. I will start out by giving you a brief description of what and oxygen sensor is, and they're general purpose.

DESCRIPTION
Four Heated Oxygen Sensors (HO2S) are mounted in the exhaust system where they monitor the oxygen content in the exhaust stream. There is an oxygen sensor mounted in each exhaust manifold and one on each end of the catalytic converter. the oxygen sensor located in the front exhaust manifold is the Bank 2 Sensor 1 (Front) sensor. The oxygen sensor located in the rear exhaust manifold is the Bank 1 Sensor 1 (Rear) sensor. The oxygen sensor located in the Y-pipe ahead of the catalytic converter is the Bank 1 Sensor 2 (Pre-converter) sensor. The oxygen sensor located in the catalytic converter outlet is the Bank 1 Sensor 3 (Post-converter) sensor.

OPERATION
An oxygen sensor acts like a battery because it creates its own signal voltage once it reaches operating temperature. This voltage is produced when the oxygen content in the exhaust stream is different than the oxygen content in the atmosphere. A lean condition (high oxygen content in exhaust) will produce a low voltage (near 0 volts) and a rich condition (low oxygen content in exhaust) will produce a high voltage (near one volt). The PCM provides a reference signal voltage (0.45 volt) and a ground to the sensor. The PCM reference voltage is necessary because the oxygen sensors do not provide their own voltage until they reach operating temperature.

HEATING ELEMENT
the oxygen sensors also incorporate a heating element inside of the sensor housing. This heating element is energized with the ignition On and allows the sensors to reach operating temperatures quickly. The PCM can then use oxygen sensor information sooner after engine start-up.

PCM INPUTS
The PCM uses oxygen sensor information during Closed Loop operation to constantly adjust fuel control to reduce exhaust emissions. Because the oxygen sensors provide information sooner after engine start-up, exhaust emissions are reduced. Faulty oxygen sensors will cause various driveability conditions and will set a DTC.

That being said...I uploaded a .pdf for you of pictures showing the locations of ALL the oxygen Sensors on your Vehicle. You can download it by clicking HERE.

I hope this helps you. If you have any more questions or need any more diagrams, please don't hesitate to ask...Thanks again, JShreader!
