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.

Where is bank 1 sensor 2 on 2000 Chevy Malibu 6 cyl Front Wheel Drive Automatic.


Bank #1 sensor #2 is the sensor located after the catalytic convertor. While sensor #1, which is located before the catalytic converter, is used to control the vehicle's fuel strategy, sensor #2 is used to monitor catalytic converter efficiency.

Location of the bank 1 sensor 2 on th engine?


"banks" refer to the sides of the engine. Bank 1 is always the same side of the engine as cylinder number one. Bank 2 is always the other side of the engine.

"Sensor" refers to upstream or downstream of the catalytic converter. Sensor 1 is upstream of the cat and sensor 2 is downstream of the cat.

Bank 1 sensor 2 would be the same side of the engine as cylinder number 1 and downstream of the catalytic converter.

Another o2 sensor ? bank 2 is the downstream but if you were looking at the front of the car what would sensor 2 be. is it right or left?


The "bank" references which side of the engine the O2 sensor is on. The "sensor" references if the O2 sensor is before the cat or after the cat.

Bank 1 is the same side of the engine as the number one cylinder. Bank 2 is the other side of the engine.

Sensor 1 is before the catalytic convert and sensor 2 is after the catalytic converter.

So bank 2 sensor 2 is the O2 sensor on the side of the engine opposite the number one cylinder and after the catalytic converter.

Need to know were the bank one , sencer one is on my buick century 2000 v6


Oxygen sensors are always numbered like this:
Bank 1 sensor 1
Bank 2 sensor 1
Bank 1 sensor 2
Bank 2 sensor 2

Some manufacturers use a kind of shorthand that reads different, but means the same thing:
Sensor 1/1 or O2s 1/1
Sensor 2/1 or O2s 2/1
Sensor 1/2 or O2s 1/2
Sensor 2/2 or O2s 2/2

Bank 1 is always the side of the engine where cylinder number 1 is located and, of coarse, Bank 2 is the opposite side.
On a 4 cylinder engine, there is only 1 bank and it is always referred to as Bank 1.

Sensor 1 is always the upstream sensor (The one located BEFORE the catalytic converter)
Sensor 2 is always the downstream sensor (the one that is located AFTER the catalytic converter.

Hope helps (remember to rate this).

I'm getting four different fault codes for my 2000 infiniti i30. I have canceled all the codes several times but they always come back within a month or two. The i30 runs fine in every respect. The codes...


Sensor 2(s) are those aft of the catalytic converter(s).
The pre-cat sensors typically fail more frequently than those post-cat.
The codes you cite are related to all sensors.
It is worth running a test of the sensors. Most garages can do the tests without any disassembly and for less than the cost of replacing any one of the four. Then you can replace the faulty unit with confidence.
