One is on one side of the engine two is on the other.
Bank one is slightly offset to the front. (about the thickness of a connecting rod give or take.)
As I really don't know why you are asking it is difficult to give an appropriate answer
Bank 1 is usually on the driver side of the motor and bank 2 is the passenger, sensor 1 is the one on the header and sensor 2 would be after the catalytic converters Bank 1 is the same side as cylinder #1. Bank 2 is the other side.
Cylinder 1 is located in Cylinder Bank One. A V6 or V8 will have 2 banks of cylinders. A 4 cylinder only has 1 bank of cylinders.
Bank 1 sensor 1 is upstream bank 1 sensor 2 is downstream
Bank 1 is the same side of the engine that cylinder 1 is onBank 1 is the same side of the engine that cylinder 1 is on
bank 1 is the bank that cylinder 1 is on
Bank 1 is the bank of cylinders that contain cylinder 1. The O2 Sensor 1 is the O2 sensor located in the exhaust system between the cylinder head and the catalytic converter, also known as the "upstream" O2 sensor.
cylinder #1 is the first cylinder from the passenger's side on the rear bank.
bank one is the side that ncludes cylinder number 1. the location of cylinder 1 varies depending on manufacterer
Bank 1 is the same side of the engine as cylinder #1.
A cylinder has 3 faces, a cone 2. A cylinder has 2 edges, a cone 1. A cylinder consists of 2 circles and 1 rectangle, a cone consists of 1 circle and 1 semicircle.
Bank 1 is the bank of cylinders that contain the number 1 cylinder. O2 sensor 1 is the first O2 sensor in the exhaust system between the engine and the catalytic converter.
Bank 1 would be the bank of cylinders that contains the number 1 cylinder. Bank 1 sensor 1 would be the first O2 sensor in the exhaust leaving the bank 1 cylinder head and before the bank 1 catalytic converter.
