The "bank" or head considered number two in your vehicle will be closest to the front of the vehicle. The O2/AF Sensor
labeled 1st from that bank will be between the engine and the fan assembly. Pop the hood look down between the engine and
the bumper and you should see a thick wire (several actually just wrapped to look like one) going from the right side of
the engine to the exhaust pipe. It will end at a conical sensor with a Hex base.
Three. Bank 1, Bank2, and a down stream.
Where is the bank2 sensor 1 located on a 2001 subaru outback 3.0
The bank 2 pre cat O2 sensor is in the rear exhaust manifold, the bank2 post cat O2 sensor is under the car after the catalytic converter, P/S nest to transmission.
The Bank1 sensor is located just above the front driveline, driverside The Bank2 sensor is located on the pass side exhaust behind the cat.
I had a similar problem with my RX300 2002. I just replaced the bank 1 sensor 1 and bank2 sensor. These are Air Fuel ratio sensors which are found before the catalytics converters. Hope it will solve your problem

There is an upstream and downstream O2 sensor (bank1 and bank2). Upstream is located close to the engine bay in FRONT of the cat converter, and 2 is located behind the converter.
Bank 2 is the drivers side of the engine in a Ford Explorer ( V6 and V8 )
oxygen sensor bank2 sensor 1 faulty
That is the downstream O2 senosr and it located after the catalytic converter on the passenger side
its connected to Muffler & Exhaust
