You state that it is number 2, so I am assuming that it is the sensor after the catalyst. Unplug defective sensor, use proper sized wrench and unscrew sensor from pipe, install replacement sensor, connect plug in, clear computer codes and road test for driveabality and your done.

Seems easy enough except for clearing the computer code. I do not have any automotive equipent. Do I need to go to the Toyota dealer (or some other garage that has a computer which can be connected?

Try a parts store, autozone, pep boys, someplace like that, they may be able to clear them for you. Or you can try disconnecting the battery overnight, but this will cause you to lose radio memory and could trigger anti theft of the radio.

Disconnecting the battery for only a minute will clear any error codes and the check engine light. If there is still a problem, the check engine light will turn on again the next time you drive the truck. I typically get the check engine due to the gas cap. This time it was the #1 Bank 1 sensor or the one near the engine manifold. I may have to buy a special tool to take that on off.
