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

    1 of 1 people found this helpful

    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
