if it is a V8 bank 2 is on the right (passenger side). sensor 1 is before the catalytic converter (sensor 2 is after)

The P1135 is set when the Engine Control Module detects a heated oxygen sensor heater circuit malfunction. This could be caused by a faulty air-fuel ratio sensor or a faulty engine control module.
P0141 is heated oxygen sensor circuit malfunction you need to check the supply voltages to the sensor.
Heated Oxygen Sensor (HO2S) Circuit Low Voltage Bank 1, Sencor 2
it means that the heated circuit decreases time that is needed to enter. When the O2 heater reaches it's right temperature the oxygen sensor commmunicates by switching according to exygen content of the exhaust that surrounds it.
Many toyota models offer heated seats
p0050 is related to an O2 sensor heated circuit problem p0125 is related to a coolant temp sensor not reading the spec. temp in a certain time limit
There is no such thing as a "circuit fault bank." That was the terminology your scan tool used to tell you that there is a fault in the downstream heated oxygen sensor circuit. There are three sensors screwed directly into the exaust system. Two you will see under the hood, screwed into exaust manifolds. Those are the upstream oxygen sensors. Now get under the truck. Find the lone sensor that looks like the other two, screwed into the exaust sytem after the catalytic converter. That is the downstream oxygen sensor. The downstream oxygen sensor circuit that there is a fault in, includes that sensor, and all the wiring in that circuit all the way back to the PCM (computer), and includes the PCM itself.
P1131 code does not show up in the book. There is a code for P0131 which is the heated 02 sensor or circuit fail.
Bank 2 sensor 2 refers to the oxygen sensor on the passenger side of the exhaust system and after the catalytic converter. heater circuit is the oxygen sensor or the wiring going to it, it is what is called a heated oxygen sensor. Google image search oxygen sensor and that is what it looks like, and they can be a bear to get out.
