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.

H2o bank 2 sensor 1 location


Bank and sensor location. Bank 1 refers to the back of cylinders that contain cylinder #1. Bank two refers to the other bank of cylinders that do not contain cylinder #1. Sensor 1 refers to the upstream O2 sensor or the O2 sensor before the catalytic convertor. Sensor 2 refers to the downstream O2 sensor or the sensor located after the Catalytic convertor. I hope that helps, let me know if you have any other questions, good luck.

This is Bank 1 (closer to the dash panel) Sensor 2 (located after the catalytic converter).

Note: A malfunctioning front oxygen sensor may cause fuel trim codes to set.
  1. Several Diagnostic Trouble Codes use specific terminology to refer to sensor location. The illustration and key below explain the following terms:
  2. Engine BANK Bank 1 is closer to the dash panel, (also referred to as RH or right hand). Bank 2 is closer to the radiator, (also referred to as LH or left hand).
  3. UP Refers to Sensor 1 or "front sensor". It is located closer to the exhaust manifold and before the catalytic converter.
  4. DOWN Refers to Sensor 2 or "rear sensor." It is located after the catalytic converter.
  5. The following examples show how to interpret oxygen sensor terminology:
  6. B1/S1 = Bank 1/Sensor 1 = Dash panel side, BEFORE the catalyst or "upstream"
  7. B2/S2 = Bank 2/Sensor 2 = Radiator side, AFTER the catalyst or "downstream"

How many oxygen sensors are in my 95 oldsmobile aurora? and where are they located?


LOCATIONS There are different locations in the exhaust system where O2S sensors are positioned. The locations have been given numbers and will be used in the accompanying charts to identify the positions of O2S sensors in most vehicles. Due to mid-year production changes or factory inconsistencies, all models may not be covered. If a vehicle being serviced is not covered in the charts, inspect the exhaust system (while cold!) in the general locations to find the applicable O2S sensors. NOTE: If equipped with dual exhaust systems, there may be up to 4 or 5 O2S sensors in the exhaust system. Be sure to locate all of them before commencing with any testing or service. Fig. 1: Location No. 1 — down pipe or exhaust manifold 79248g01.gif
Fig. 2: Location No. 1 — typical O2S sensor located in the exhaust manifold 79248g04.gif
Fig. 3: Location No. 2 — left and right banks of a V-type engine 79248g02.gif
Fig. 4: Location No. 3 — exhaust collector (where more than one pipe joins together) 79248g05.gif

WHERE IS MY OXYGEN SENSOR LOCATED


On almost every car, there is an O2 sensor located in the front, on the exhaust pipe, or manifold, and there is an O2 sensor located after the Catalytic converter. The front O2 sensor is the most important because it monitors the air/fuel ratio. The rear O2 sensor checks your Cat converter for proper operation and filtering.

O2 sensor?


The O2 sensor is located in the exhaust pipe prior to the catalytic converter. You'll have to get under the vehicle to see it or replace it.
