This code is most often caused by a failure in the heater element of the oxygen sensor itself. Bank 1 is the engine side that has the #1 cylinder in it...typically the rear bank on a V6 and the only bank on a four cylinder. You also need to know if it's sensor 1 or 2...if memory serves, P0135 is the sensor 1 or sensor on the engine manifold ahead of the catalytic converter. Careful when removing, they like to seize in the manifold, and if you damage the threads you'll have to replace it as well.

If it is saying that the heater circuit has failed then this O2 sensor has failed. The o2 sensors have tip heaters in them. These are irreplaceable. Replace the whole sensor. This particular sensor is located on the driver's side exhaust in front of the Catalytic Convertor.

It is the one on the passenger side behind the catalytic converter
There are 2 catalytic converters on a V8 2002 Toyota Tundra. Bank 1 is the manifold and cat on the drivers side and bank 2 is the manifold and cat on the passenger side. Sensor 1 is the sensor on the exhaust manifold before the catalytic converter. Sensor 2 is the sensor located after the cat converter. Bank 2 Sensor 2 is the sensor located after the catalytic coverter on the passenger side.

The O2 sensor heater circuit helps warm up the O2 sensor. The purpose of this is to allow O2 sensor to get to normal operating temperature without having to wait for exhaust pipes to warm up so it can give accurate readings. It is built into O2 sensor.
9 time out of 10, the heater circuit internal to the sensor has failed. Replace the sensor.
