On most ford vehicle you will find the air sensor or the air pressure valve on the rear of the engine closest to the windscreen side.
some have the air lamda attached to its exhaust system this will control the O2 mix

Where is the 02 Oxygen Sensor before the cadalic converter on a 2006 Hyundai Santa Fe


Usually these are located on the exhaust manifold or just below the exhaust manifold and you should be able to see it in the engine bay. On V6 engines there will be one sensor on each of the 2 exhaust banks.
You will probably need to remove the engine cover to see the sensors on your exhaust.

If someone told you to replace these because you got a particular fault code I would be wary. A decent scan tool and basic diagnostics can show if the 02 sensor is working or not. Some faults often blamed on an 02 sensor are not due to faulty sensors.

How to change upstream o2 sensor on 2008 chevy uplander 3.9l ?


  • 1 Warm up the engine for about four minutes to bring it to operating temperature. Then turn off the engine. This will avoid damage to the exhaust pipe threads if that sensor has seized to the pipe.
  • 2 Find the oxygen sensor or sensors you need to replace. The upstream sensor is located near the exhaust manifold and the downstream sensor on the back exhaust pipe, close to the catalytic converter.
  • 3 Disconnect the oxygen sensor electrical connector. Depending on your particular Chevy model, both sensors may be disconnected from the engine compartment.
  • 4 Lift the front of your Chevy model to reach the sensor you need to change, if necessary. Use a floor jack and two jack stands to support it.
  • 5 Remove the oxygen sensor using a box-end wrench or a ratchet and oxygen-sensor socket.

    Where do i find all my oxygen sensors on my april 1993 isuzu rodeo?


    The O2 sensors are located in the exhaust pipe just off the exhaust manifold. Here is a picture of your particular O2 sensor, some are slightly different looking it depends on the manufacturer. You will need to get under the truck to replace the sensor it takes a special 7/8" O2 sensor socket, about $5 from Autozone.

    Were on exaust is oxygen sensor in 1999 subaru impreza auto sport


    On the SOHC engine the front (A/F) oxygen sensor is located in the front section of the front catalytic converter. The rear oxygen sensor is located in the rear section of the front catalytic converter. On the DOHC engine the front oxygen sensor is located in the front section of the exhaust system, just past the crossover pipe. The rear oxygen sensor is located in the front section of the catalytic converter.

    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!
