Testimonial: "yep I saw that when I first googled for it's location... and wasn't even in the vicinity.. so I'm guessing that isn't a drawing for the rx300..lol"
SOURCE: Code P1135 for 2002 Toyota Rav4
its the sensor on the drivers side of the exhaust manifold........ it might be an air fuel ratio meter and not an o2 sensor.. good luck jimmy
SOURCE: location of the bank 1 sensor 2 O2 sensor on a 2001 ford escape
B1 means the sensor is located on the same bank of the engine that has the #1 cylinder. B2 is located on the opposite bank.
S1 means the sensor is located BEFORE the catalytic converter
S2 means the sensor is located AFTER the catalytic converter
You didn't say which engine you have, so I've included the diagrams of both 4 cyl and 6 cyl so you can see the banks

What was the code? lean mixture? If so make sure there is no leak in the exhaust. I have worked on a lexus suv, but it was an 89. It had a lean mixture code. After examination I noticed a exhaust leak which was not apparent at first, there is a section in the exhaust the is very thin, and prone to leakage, causing the lean mixture code.
SOURCE: where is the bank 2 sensor 1 located.
Oxygen sensors are always numbered like this:
Bank 1 sensor 1
Bank 2 sensor 1
Bank 1 sensor 2
Bank 2 sensor 2
some manufacturers use a kind of shorthand that reads different, but means the same thing:
Sensor 1/1 or O2s 1/1
Sensor 2/1 or O2s 2/1
Sensor 1/2 or O2s 1/2
Sensor 2/2 or O2s 2/2
Bank 1 is always the side of the engine where cylinder number 1 is located and, of coarse, Bank 2 is the opposite side.
On a 4 cylinder engine, there is only 1 bank and it is always referred to as Bank 1.
Sensor 1 is always the upstream sensor (The one located BEFORE the catalytic converter)
Sensor 2 is always the downstream sensor (the one that is located AFTER the catalytic converter.
Most GM engines have #1 cylinder located on the left bank, (or Driver's Side) of the engine,
So, the answer to your question would be that you are looking for the sensor located before the catalytic converter on the right (or Passenger Side) of the truck.
SOURCE: were bank 1 sensor 2 located on a 1997 tahoe
