Bank one, sensor two is a specific sensor within a car. This sensor will be on a car with either six or eight cylinders. The sensor detects oxygen and will let you know that your engine is running well and at the capacity that it should be. This will warn you if there are issues with the sensor and when you need to get the engine looked at, to prevent any damage to the car. These are seen as a warning when they first go off, not a sign of severe damage to the engine.
These are located in different place on different makes and models of car but there is logic to where they are located. The bank is either the left or right hand row of cylinders, your manual should tell you which bank is numbered one and which is numbered two. In a V6 there will be 3 cylinders in each bank and in a V8 there will be 4.
The sensor number refers to whether the sensor is before or after the converter. This will depend on make and model and you should have a look at your manual for this information.
This should now point to where bank one, cylinder one is.
If you have a warning light on this, you will have a problem with your engine. Do not leave it. This will cause lower efficiency, lower acceleration force and higher emitions. Your car will work at a rate of 20% less and use 20% more gas.
Go and have this looked at and it should be an easy problem to fix. It could just be that the sensor is getting old and breaking it could mean that there is anti freeze contamination, high oil usage or silicone in the engine.
