    Default Help!!! Bank 2 sensor 1...where??

    Ok, so my O2 sensor went out a couple of weeks ago. I received a printout that said the sensor that was out was bank 2 sensor 1.
    I first go to PepBoys, since its by my house, and asked them.
    The guy looks up at the sky and goes, "Hum, lets see now. Bank 2, sensor 1, that is the driver's side behind the converter."
    I then go to Toyota dealer and he didn't ever know where to start. He said his computer only says 1,2,3, and 4.

    So I took the PpepBoys word and replaced the back left sensor...WRONG!! $130 later.

    WHERE IS BANK 2, SENSOR 1 PLEASE!!!

    That is the passenger side upstream oxygen sensor. It is locatedon the rear end of the exhaust manifold. The dealership should replace it free of charge.

    Ok, that is the third DIFFERENT location I have been told.

    Originally, it was back, driver's side...then yesterday I was told front, passenger side.

    I am going to need a little more re-assurance.

    nedjames is right. Passenger side, before the cat. Bank 1 is the drivers side, Bank 2 is the passenger side. Sensor 1 is upstrem, before the cat, sensor 2 is downstream, after the cat.

    - see attached - There is a Warranty Extension on these sensors to 7 years or 90,000 miles from the vehicle's in-service date, whichever occurs first.
