In a 2005 Lexus ES330, there are a total of four oxygen sensors. The first sensor in Bank 1 is located on the front header assembly right before the downpipe connection. The second sensor in Bank 2 is situated on the top of the rear header where the first and second outlets converge. Moving on to the third sensor in Bank 1, it can be found on the Y-pipe midway between the catalytic converter and the headers. Lastly, the fourth sensor in Bank 1 is positioned just after the catalytic converter, facing the passenger side of the vehicle. To access these last two sensors, you will need to go under the vehicle. It's recommended to use a special oxygen sensor socket to remove the sensors properly without causing any damage.
