I had to replace both o2 sensors on my 2002 Tundra after about 50K. Toyota recalled this problem afterwards and refunded my money. My solution to you is to not worry about which one is bad and go ahead and replace both, because I had one bad and before I could replace it the other went bad also. PS: You'll have to purchase a special socket to remove them and unless you pruchase the Toyota product ( I used O'Reilly parts), you have to cut and splice the wires with a waterproof splicing kit included with the sensors. Just follow the instructions, not a hard job.

That code will not affect the drivability of the vehicle. The heater does just that: it heats up the oxygen sensor to operating temperature. You can change it yourself, raise the vehicle up, the sensor is the one on the passenger side, right after the exhaust manifold.
Thanks for choosing FixYa for advice!

If you used the type you splice the wires, recheck the wires. Sensor 1 should have been the one up closest to the exhaust manifold. I prefer to pay $30 more and get the OEM plug-in type. You might try disconnecting the battery for a while.

In that particular engine the sensor that you have is the one in the driver side, but based in my experience you have to replace both, the same in tundras, the computer sees a fresh new, fast signal, from the new sensor and thinks that the sensor and the opposite bank fail.
