      • Q:

        I have a 2006 Toyota Sienna XLE. I need a Bank 1, Sensor 1 oxygen sensor. How does this correspond to your teminology "downstream front"?

          I'm glad to assist, BW! Your 2006 Toyota Sienna XLE is indicating that the oxygen sensor that has failed is in the exhaust stream from cylinders 1, 3 and 5 which are on the side of the engine closest to the cabin. Sensor 1 indicates that it is an upstream sensor that has failed (pre-catalytic converter). This Denso Oxygen Sensor - Direct Fit (Part No. 234-4168), if failing, will provide a diagnostic trouble code indicating Bank 2, Sensor 2. You would want to look for an upstream rear indication like Denso Air Fuel Sensor - Direct Fit (Part No. 234-9012)
