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: o2 sensors in a 97 gmc 1500 with 5.7 liter

bank 1 is the drivers side bank, so b1s1 would be the drivers side closest to the engine. if the truck is equipped with several 02 sensors then bank 2 or b2s1 would be passenger side closest to the engine. those are called upstream o2 sensors and the others downstream b1s2 and b1s2 b= bank 1= drivers side s=sensor 2=downstream. hope this helps.

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.

Where is the oxygen sensor on a 2008 chevy uplander?


they are located in the exhaust system. if you follow the exhaust pipe from the manifold you will come across the sensor/s and it will have an electrical connector. there is more than one sensor in the system so it depends which sensor your after. bank 1 sensor 1 is on the side cylinder 1 is on and its the first sensor you come to on that exhaust pipe bank 2 sensor 1 is on the opposite exhaust side and the first sensor you come to.

What place is the bank 1 censor 3 on a s10 98 located


  • Bank 1 is referring to the side of the motor with cylinder 1, usually the driver side. And it would be the 3rd sensor back. Its probably not dual exhaust so its just referring to the rear o2 sensor located after the catylitic converter. Hope this helps.

Locate o2 sensor bank 2 sensor 2


Depending on what type exhaust you have ( dual or single) you will have several oxygen sensors. The bank # XXXXX means it is one of the o2 sensors on drivers side. The sensors are located screwed directly into the exhaust pipe at different spots. See below. You will have say sensor 1/1 which means sensor 1 / bank 1 etc..

NEED TO KNOW THE LOCATION OF BANK 1 SENSOR 2 ON A 2001 TOYOTA AVALON


If single exhaust pipe, look for the bank 1 sensor 2 oxygen sensor to be either stuck into the side of the catalytic converter or just downstream of it.

If dual exhaust pipes, look for the bank 1 sensor 2 oxygen sensor to be just downstream of the catalytic converter for the bank of cylinders that contain cylinder 1.

Whats the difference between up and downstream sensor on a chevy s10 1997, what exact sensors do i need for bank 1 and bank 2 sensor1


Well upstream from the Catalatic Converter means towards the engine and that would be the location for Sensor #1 on both sides of the engine. And Downstream would be away from the engine past the Catalatic Converter For Sensor #2 on both sides of the engine. Bank 1 or Bank 2 would indicate which side of the engine the trouble is on. ( Bank #1 is the side of the engine that contains #1 Cylinder. Please remember if you are going to change one 02 Sensor then you should change all of them and be sure to clear all codes after all repairs are finished. that will turn the check engine light off. Good Luck and have a good XMASS.
