O2 Sensor

Where is the bank 2 sensor to O2 sensor located on a 2009 Rav 4wheel drive automatic 6 cylinder? Would it be the one with the grommet on it going into the floor pan? Could anybody help me please??? Thanks!

There are two bank 2 sensors. The first is the "air fuel sensor" and the second (after cat) is the heated oxygen sensor.

02 sensors

Thank you for the diagram,should be a big help. I talked to a few mechanics at work and one of them said to (1) check for any corrosion at the connections,the one with the grommet going inside the floor pan gets bad cause its located under the rug,which is wet part of the time.(2)Check your fuses.(3)Look for exhaust leaks...I already replaced the bank 2 sensor 2 and engine light came back on.Thanks again Carbon

I might need it dumbed down even more for myself. Is it located in the front/rear, drivers side/passenger side?

B2S2 sensor is the heated sensor. It is at the bottom end of the front catalytic converter. It would be accessed from under the car. You might have to pull the plastic undershield off to get to it.

I believe all the O2 sensors are electrically heated, no?

There are two O2 sensors for each of two banks. The first is called the air/fuel sensor. It is also called the wideband sensor and the upstream sensor. No heater.

So far so good,had a code PO158 and replaced the 02 sensor in the front bottom of the Rav after the cat, left side of engine. Engine light did come back on and I rechecked my connection and tightened the sensor to make sure there is no exhaust leaks.Seems ok,so far
