The engine light on my 2016 ES350 came on. So I took it in to the dealership to find out what was the issue. They came back with the Oxygen Sensor Bank 2, Sensor 2 was needing to be replaced. They wanted around $750 to replace it. I am fairly handy wanted to but the parts and replace it my self but am having a hard time finding a diagram of the oxygen sensors for this generation of ES's. Any idea as to where I can find a diagram for the 6th generation of Lexus ES350?

Thanks in advance.

 

Try the online Lexus parts, they usually have diagrams for all the parts.

 

how many miles. i thought o2 sensor last a while.

 

Do you know the codes that came up? That's a pretty steep price. If you do need it replaced, at least the downstream sensor is a lot cheaper than sensor 1. It is not too hard a job if you can get under the car, although some can be difficult to break loose. This might help.

>Oxygen Sensor Bank 2, Sensor 2

Just a thought, that could be the rear bank (i.e., firewall side), and everything over there is *itch to get to ...
