bank 1 refers to the side of the engine that #1 cylinder is on , and sensor 2 refers to downstream , after the catalytic converter. , this link shows bank 1 on a 2001 nissan maxima V6 being on the firewall side . if you had a 4 cylinder it would be downstream after the catalytic converter .

SOURCE: location of the bank 1 sensor 2 O2 sensor on a 2001 ford escape

B1 means the sensor is located on the same bank of the engine that has the #1 cylinder. B2 is located on the opposite bank.
S1 means the sensor is located BEFORE the catalytic converter
S2 means the sensor is located AFTER the catalytic converter

You didn't say which engine you have, so I've included the diagrams of both 4 cyl and 6 cyl so you can see the banks

2008 kia spectra 4 cylinder heater circuit sensor 1 bank 1 location


It is the first O2 sensor you come to on the exhaust system. Usually in the exhaust manifold or catalytic converter. Heater circuits are 99% of the time the O2 sensor...1% is wiring on the harness side..

1998 bmw 328i 02 sensors connectors


bank 2 sensor 1 is a heated oxygen sensor in the manifold or exhaust before the cat converter
it is not an o2 sensor which is oxygen sensor after the cat converter for bank 2
two completely different sensors
the fuel trim code appears because of the problem sensors
the fuel trim is cpu program in the computer in the ECM setting a optimum fuel /air ratio after a period of driving
if the sensors both HO2s and O2 sensors are faulty then the cpu cannot set the fuel trim

Thanks for choosing FixYa and welcome. You need to change the 02 sensor. This is the sensor in the back. It is called a oxygen sensor. It is located on the exhaust system.

Where is fuel trim bank 2 located on bmw 2000 740i bmw


Are you getting the code P0173 That would mean that the ECU was unable to set the correct mixture for cylinders 4-6 (bank 2). I'd guess that the most likely culprit for that failure would be a failing pre-cat O2 sensor based on the code alone.The pre-cat O2 sensors are a critical part of the feedback loop for mixture control. When an O2 sensor ages enough it no longer delivers a valid signal to the ECU, which can cause this fault. The only other component that will affect only bank 2 is the catalytic converter for that bank. Given relative costs of O2 sensors and catalytic converters I'd change out both pre-cat O2 sensors and see if that helps. FYI: O2 sensors are usually staring to fail at 80-90K.

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"

My 99 gmc sierra 2500hd has a bad o2 sensor sensor 1 bank 2 is that pass side front


bank 1 always refers to the bank that the No.1 cylinder is located and bank 2 is the other bank. Senspr 1 refers to the upstream oxygen sensor ( before the catalytic converter) sensor 2 refers to the downstream o2 sensor(after the cat) So if your No.1 cylinder is on the left side(drivers side) then your assumption is correct.
