AF sensor malfunction bank 2 sensor 1

Common problem, this bank and sensor are located in front by the radiator, if you are the one to perform the repair, when you crack the sensor open spray w40, then continue getting it loose, some times jams and damage threads in the exhaust manifold.

Often when the vehicle has lots of miles, there is a need to replace both af sensors, if you replace af bank 1 today, the computer sees a healthy signal and compares the readings to the other old sensor, then sees the difference and sets a code for the other sensor.

P0051 code, where is the sensor located, where is bank 2 sensor 1 located on truck, 2003 4.7 engine, tundra truck

Bank 2 is passenger side, sensor 1 is the one up closest to the exhaust manifold. Plug in type (just remove old and plug back into the wiring harness connector) is about $90 at Autozone. You can get a cheaper one that you splice but it's confusing to understand which wires to splice together. Don't forget to buy the special socket, $10, to remove and install the sensor. It's split up the side for the wires. Forget trying to use an open end wrench, socket is best.
