    This air fuel sensor fixed the error code P0051 on my '09 Sienna.

    This air fuel sensor fixed the error code P0051 on my '09 Sienna and is the correct part for the bank 2, sensor 1 part which is located on the front exhaust manifold upstream of the catalytic converter. Some parts stores call it the left upstream sensor.

    I only gave this part 4 stars because the store recommended purchasing part 234-4512 to replace the Bank 2, Sensor 1 part based upon the error code. I've been burned before so I decided to remove the bad sensor in order to see what it looked like before ordering. Good thing I did as it looked nothing like 234-4512. Do your homework before ordering any sensor. Waiting another 3 days to get the right part is aggravating.

    Installation was fine after running a M18x1.5 tap through the bung. I buggered up the threads taking it off while it was still hot. You might have success using a thread chaser, available at Autozone, but I opted for an actual tap which cost around $16 at Ace Hardware. I was very surprised they had one this size but it is a common size for spark plugs.

    I would recommend getting the oxygen sensor loaner tool. The socket I bought from Harbor Freight was so loose on the sensor that it nearly stripped the head on the sensor. The loaner tool had a much smaller slot for the wires and therefore made much better contact with the bolt head on the sensor. Finally, don't forget the anti-seize. It comes with the sensor which was nice.

    Pros: Sensor comes with anti-seize

    Cons: Not an in-stock part
