Follow the driver side exhaust pipe from the manifold back to the second CAT. After the second CAT is the #2 oxygen sensor. A 7/8 wrench and a tap with a hammer on the side of the wrench should get it out. After all that work, never put an old sensor back in.

SOURCE: where is the bank 2 sensor 1 located.

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.

Most GM engines have #1 cylinder located on the left bank, (or Driver's Side) of the engine,

So, the answer to your question would be that you are looking for the sensor located before the catalytic converter on the right (or Passenger Side) of the truck.

SOURCE: where is the bank 1 sensor 2 o2 sensor for a 96

Oxygen sensors are numbered by which bank of cylinders they serve. Bank 1 is the left or drivers side bank of cylinders on the 4.3L which has the odd numbered cylinders 1,3, and 5. Bank 2 is the right or passenger side bank of cylinders numbered 2, 4, and 6. The Bank 1 Sensor 1 would be the sensor for the left hand side of the engine AHEAD of the converter. Bank 1 Sensor 2 is the sensor for the left hand side bank of cylinders BEHIND the converter.

Are there two oxygen sensors on a chevy suburban or four its a wheel drive with a v-8 our


Hi, if the suburban is 1996, or newer, you will have 4 O2 sensors. The sensor mounted before the catalytic converter, is sensor 1, and the sensor after the cat, sensor 2. These can also be referred to as pre, or post. The driver, or left side of the engine, is bank 1, as the passenger, or right hand is bank 2. years prior to this, use 1 O2 sensor. Good luck...Coop
