The 2001 Dodge Ram 1500 bank 1 sensor 1 location is one of the four oxygen sensors on the car. The oxygen sensor is in charge of making sure that the car has enough intake to facilitate combustion. If the sensor is not working right then You will need to get it fixed sooner rather than later. If You don't then You will find the car is running rich or lean, meaning the air to fuel mixture is not correct. This can make it harder for Your engine to work and will do damage to it over time. Sensors are very cheap to replace, so there is no reason the ignore them for a long time.
