That's a code for the heater circuit for the bank 1 sensor 1 O2 sensor. Bank one is always the same side of the engine as the number 1 cylinder (V-6 engines). Sensor 1 is always before the catalytic converter.

Code 135 is for a faulty heater in the O2 sensor. Since you have replaced the sensor the problem is probably the circuit or the power source for the heater.
You'll need to check the heater circuit next.
