Do you know which cylinder on the engine is number 1? Bank 1 is always the side where the number 1 cylinder is located. Bank 2 would be the opposite side. Sensor 1 is always the oxygen sensor nearest to the engine. Sensor 2 is the sensor after the catalytic converter.

SOURCE: location of a o2 sensor 2001 nissan maxima

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: 2002 Pontac Grand Prix GTP P0171 code engine stumbling at times

Bank 1 is the frt side exhaust manifold (did they say bank 1 sensor 1?),you can start by replacing that sensor,i would check the intake for leaks ,the gm 6cly. are known for bad intake gaskets,you will see oil coming out form the frt or rear of the intake,also check your atifreeze overflow bottle for bronwish sludge,which means that the oil is mixing with the antifreeze.A leaking intake could cause that lean condition.

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

SOURCE: need to locate o2 sensor location bank 1 sensor 2

You need to check two things.

First, there is a heat shield on top of the front of the motor where the o2 sensor you already replaced is. It's got (4) 12mm bolts. Remove it and check the exhaust manifold (big thing you put the o2 sensor into) for cracks. If there are any cracks, you'll get o2 sensor codes. Replace the manifold.

Second, if the manifold is fine start the car and listen to the exhaust pipe under the engine for leaks. Or if you already know the exhaust is loud... that's gonna do it too. A leaking exhaust pipe on an Accent will set secondary o2 sensor codes.

SHOULD you try to change it yourself, you will need a 7/8" wrench, and a new o2 sensor, or flex pipe, or manifold depending on what's broke. Do NOT touch the tip of the new or old o2 sensor to ANYTHING when you take it out or install it or it will be ruined permanently. Run the car until it's at it's normal operating temperature. Raise the vehicle, and take the o2 sensor out of the car (see below to understand which one) using the 7/8" wrench or if you got fancy and bought an 02 sensor tool... use it.

Replace whatever parts are bad (manifold or pipe) or just replace the sensor you need. Then restart the car and take it to a parts store and have them clear the code. The code (and check engine light) won't return right away, it usually takes a few days. If you did everything right you should be good. If not, it's not a terribly expensive job to have done and by now you should be able to explain to them what's wrong based on what you found when you looked at the car. Just tell them everything you checked and what you saw.

Education: I'm not sure where that half baked answer about o2 sensor 1 being near cylinder one came from but here's the real deal.

Sensor 1 is always BEFORE the catalytic converter
Sensor 2 is always AFTER the catalytic converter

Bank 1 and Bank 2 refer to which SIDE of the exhaust on 6 and 8 cylinder engines. Bank 1 is usually left side, Bank 2 is usually right side.

So... O2 sensor B1S1 refers to the O2 sensor BEFORE the converter on the LEFT side of the motor.

Where's the bank 1 sensor 1 located at my toyota sienna 2007, i know there are 3 sensors in bank 1 and 1 sensor in bank 2 if you can give me the image or view where they are located i really appreciate...


O2 sensors location is broken down like this. The bank refers to which side of the motor the sensor is on. Bank 1 is the same side of the engine as the number one cylinder. Bank 2 is the other side of the motor. Sensor refers to either before the cat or after the cat.

Bank 1 sensor 1 would be the O2 on the side of the motor that the number one cylinder is on and before the cat.

The number one cylinder is on the back side of the motor (the side closest to the firewall). The O2 sensor will be in the exhaust pipe near the exhaust manifold.

Where is o2 sensor 1 located on a 2002 aztek any help would be greatly appreciated


Which one? Your vehicle is equipped with 2. One is in the exhaust manifold on the left bank and the other is in the exhaust pipe after the catalytic converter.

NOTE: Most O2 sensor codes do not mean that the O2 sensor should be replaced. Most of the time, the O2 sensor is only reporting the failure of one of the other system components. To save time and money, I personally recommend having the vehicle diagnosed by a qualified service technician. I have seen many people spend hundreds of dollars on O2 sensors only to find out that the problem was caused by something else. Case in point: One man spent nearly $500 replacing all 4 of the O2 sensors on his Ford F-150 Pickup only to have the O2 Sensor code return 2 days later. He brought the vehicle to me and I fixed it with 50 Cents worth of vacuum tubing. O2 sensors do fail, but about 70% of all the O2 sensors that get replaced do not fix the problem that caused the O2 Sensor fault code. Fault codes Never tell you what parts to replace. They only tell you which of the many parameters monitored by the computer is out of specification. Proper diagnosis is required to find out why.

CODE PO155 BANK2 SENSOR 1 WHERE IS THIS SENSOR LOCATED?


A code P0155 may mean that one or more of the following has happened:
* O2 Heater element resistance is high
* Internal short or open in the heater element
* O2 heater circuit wiring high resistance
* open or short to ground in the wiring harness

Possible Solutions:
* Repair short or open or high resistance in wiring harness or harness connectors
* Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)


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 have a saturn Ion and need to know where the O2 sensor is located. It is a 2006 4cyl 2.0. I am not sure if it is before the converter or in the rear of the converter.


There will be an O2 sensor before the catalytic convert and one after the catalytic converter.

On a four cylinder the one before the cat will be Bank 1 Sensor 1. The one after the cat will be Bank 1 Sensor 2.

Do you have a trouble code for an O2 sensor?

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"

Bank one is toward the front of the vehicle. Sounds like the heated oxygen sensors have gone bad. The Oxygen Sensors are located in the exhaust pipe and require a special socket to remove and replace.
