It depends on the engine/manufacturer. For example, Chev 350: #1 is left bank front, #2 is right bank front. Answer The above is true, but in addition there is a visual way to tell as well. If you look at the engine block you should be able to see one of the cylinder heads, or the forward part of the casting in the block is ahead of the other side (this is because if you look at the internal components of the engine you will see 2 connecting rods will be on a single journal of the crankshaft of any V configured motor one piston is slightly ahead of the other, modern maching and casting of engine blocks will have a slight setback on one side; I am not sure but this may not be the case on very old engine blocks due to far less sophisticated casting and machining prior to the end of WWII ?) In every case that I have seen the forward most cylinder is the #1 cylinder. Additionaly Chevy does number there cylinders alternating like described above, Ford will number 1-4 on one bank 5-8 on the other in either case the forward most cylinder is the 1# cylinder.
Bank # 1 is the passenger side of the engine
On the exhaust pipe It is before the catalytic converter on the same side as cylinder #1.
Bank 1 is the passenger side of the engine , bank 2 is the drivers side of the engine
Bank 1 would be the bank of cylinders that contain cylinder number 1. Bank 1 on the 3.9 would be the bank of cylinders located on the drivers side of the engine. Bank 1 sensor 2 would be the O2 sensor located after the catalytic converter.
Bank 1 is the drivers side of the motor, making bank 2 the passenger side of the engine. Bank 1 Sensor 1 will be located before the Catalytic converter, Bank 1 Sensor 2 would be located after the Cat. This is of course assuming your vehicle is equipped with the California emissions having a total of 4 O2 sensors.
Bank 1 would be the bank of cylinders that contain the number 1 cylinder. If it is a 4 cylinder engine there is only one bank. So, bank 1 sensor 1 would be the first sensor you come to in the exhaust system leaving bank 1 of the engine.
Bank 1 is the bank of the engine that contains #1 cylinder. Bank 2 is the other bank. Sensor 1 is located before the catalytic converter. Sensor 2 is located after the cat converter.
Assuming this is a 4.3L engine, bank 2 sensor 1 would be the first O2 sensor located in the exhaust header pipe on the passenger side of the engine.
Bank 1 = The side of the engine the Number 1 cylinder is on Sensor 1 = between engine and catalitic converter Sensor 2 = After cat...
On a Ford Mustang ( V6 and V8 ) Bank 1 is the passenger side of the engine
Bank 2, Sensor 1 is located on the front of the engine(radiator side), before the first catalytic converter.
: Research shows that bank #1 is the side of the engine where number 1 cylinder is located. On a 2001 Nissan Maxima that is on the back side or firewall side of the engine. That makes bank #2 the front or radiator side. == ==
Bank 1 sensor 1 is screwed into the exhaust manifold on the back of the engine. Bank 1 sensor 2 is screwed into the catalytic converter.Bank 1 sensor 1 is screwed into the exhaust manifold on the back of the engine. Bank 1 sensor 2 is screwed into the catalytic converter.
the bank 1 sensor one is located up steream on the exhaust manifold eo next to the engine
Bank one is the side of the engine with cylinder #1. Sensor two is after the catalytic converter.
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
passenger side is bank 1 the closest to the engine is sensor 1 of the 2 on each side
Bank 1 is the drivers side of the engine and sensor 1 will be the closest O2 sensor thats in the exhaust pipe where it bolts to the engine exhaust manifold.
the 02 sensors are located in the exhaust system. bank one stands for the same side as the number 1 cylinder. sensor 1 is the first sensor in the bank, (closest to the engine or upstream) Bank 1, Sensor 1 is on the right side of the engine (fire wall side) before the cat.
Bank 1 is the same side of the engine that cylinder 1 is on.
Same side of engine as cylinder 1.
Bank 1 is the drivers side of the engine.
bank 1 should be the left exhaust manifold.
Bank 1 on that Town car would be the passenger side of the engine. Bank 1 Sensor 1 would be the first O2 sensor in the passenger side exhaust after the engine but before the catalytic converter.
Bank 1 is the passenger side of the engine in your E-150 Sensor 1 is between the engine and the catalytic converter ( upstream sensor )
