Bank One and Bank Two are usually a standard layout. Look at the engine and stand with the belts and pulleys nearest to you. You will probably be standing in front of the vehicle looking towards the rear of the car. Bank One is the Left side of the engine. Bank Two is the Right side of the engine. Cylinder One will be the cylinder on the Left (Bank One), and nearest to you. Please use the attached image for reference. The front of the engine is also the front of the vehicle.

SOURCE: How about when u have 2 catalytic converters in the same bank 1.?

If you have more than 60K miles start by replacing the Oxygen sensor(s) that is(are) installed after the catalytic converter(s). 
P0421: Warm up catalyst efficiency below threshold. This code means that the computer is detecting the catalyst not warming up to full function quickly enough based on information from the post cat O2 sensor. 

Good luck and hope this helps.

Bank 2 is the bank that is farther back than the other when looking at eng from the front you will see that one cyl head is farther forward (closer to radiator than the other. this is #1 Bank) #2 is the opposite and sensor #2 is the one after the Catyliac Convertor towards the muffler. #1 sensor is between head and Cat.

Warm up catalyst efficiency below threshold bank1 on galant 02 v6: someone pls tell what is this ? and where is bank1 located on this car ?


unfortunately you will need to replace your catalytic converter. Bank one is the bank which contains the number one cylinder. If you locate the number one cylinder you can determine which catalytic converter needs to be replaced. Hope this helps

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).

Hi, I need to take my 2001 Mazda 626 4cyln for SMOG check in CA. But its check engine light is on, diagnosed as code P0421. Appreciate your help to fix this problem, or just to pass the check. Thank you.


CODE P0421. DEFINITION-CATALYST EFFICIENCY LOW-BANK 1. EXPLANATION-THE OXYGEN SENSORS MONITOR THE CATALYTIC CONVERTERS ABILITY TO STORE OXYGEN. PROBLEM CAUSES- 1. CATALYTIC CONVERTER DEFECTIVE (FAILURE POSSIBLY DUE TO #2,3, OR 4) 2. ENGINE MISFIRE OR RUNNING CONDITION. 3. LARGE VACCUM LEAK 4. ENGINE OIL LEAKAGE INTO EXHAUST-VALVE GUIDE SEALS, PISTON RINGS. THE PCM HAS DETERMINED THAT THE WARM UP CATALYST EFFICIENCY FOR BANK 1 IS BELOW TRESHOLD FOR THE CURRENT ENGINE OPERATING CONDITION. (BANK 1 IDENTIFIES THE LOCATION OF CYLINDER #1, WHILE BANK 2 IDENTIFIES THE CYLINDERS ON THE OPPOSITE BANK).

replace O2 sensors, or your Catalytic Converter.

Need to pass emissions test, dianostic test - Catalyst efficiency blow threshold (bank 1) tried to order part - now I need to know if it pre or post, left or right Oxygen sensor, can it be determined by...


Yes it can be determined by the DTC (Data Trouble code). If the DTC is P0420 (catalyst system efficiency below threshold Bank-1) then the side of the engine with the #1 spark plug and cylinder is always Bank-1, and the O2 sensor that monitors the catalyst efficiency is usually after or (post) of the catalytic converter.

The #1 cylinder is located at the front spark plug on the right or the passenger side of the vehicle, so Bank-1 is on the right side of the vehicle, and the O2 sensor that monitors the catalyst efficiency should be located after or (post) of the catalytic converter. It would be the post right O2 sensor.

There is also the possibility that the catalytic converter is actually starting to fail, and if changing the O2 sensor and clearing the DTC does not solve the problem them the catalytic converter is most likely faulty.

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.

How do I fix a bank2, 02 sensor?


just a quick note: bank 2 is LEFT side (drivers) on a rear wheel drive vehicle ,on front wheel drive vehicles it would be the front side when looking down from the front of the vehicle ,Sensor 2 is after the cat converter! if you replace that sensor, clear the codes or have someone clear them for you and you should be all set.
the 2 of bank 2 is the 2nd oxygen sensor that is located after the catalytic converter.usually closer to the tailend of the header pipe.
The sensor I believe you are looking for is in the exhaust pipe or exhaust manifold, usually the right bank which is on the right side of the car (driver is left), or close to the firewall if engine is mounted sideways. Some cars are equipped with a sensor behind the catalytic converter that tells the computer the HEALTH of the converter only. It has nothing to do with running of the engine per say.
Bank 1 is which ever side has cylinder 1. It could be left or right. Bank 2 would be the other side. Bank 1 sensor 1 would be before the catalytic converter. Bank 1 sensor 2 would be after the converter. The same applies with bank 2.

I need to know the location of sensor 2 bank 2 on a 2001 maxima


this sensor would be in the right bank as you face the ngine from under the hood, it is the sensor before the catalytic converter in the exhaust pipe, u will need a 7/8" wrench or special O2 sensor socket to replace it, the tool type depends on how hard it is to remove, spray the threads with WD 40 before trying to remove. go to the link to see the oreintation of your engines cylinder banks, bank 2 has cylinder numbers 2, 4 ,6 in it.
