Your question was truncated. I see that the bad sensor is on bank 1, but I can not see if it is the upstream (sensor 1) or downstream (sensor 2) sensor. The upstream sensors are mounted in the exhaust manifolds (look sort of like spark plugs) and have wires going to them.
You will need a 7/8" or 22mm wrench to remove the sensor (after disconnecting the wires). If your car has over 70,000 miles I STRONGLY suggest that you replace BOTH upstream sensors. One in each exhaust manifold.

I'm sorry you replaced the parts without testing first. Codes only give mechanics a suggested area to test, not which components to replace.
Since you replaced the O2 sensor for the first two codes, a mechanic will need to check to see if it is working by reading the data flow from the sensor with a scanner while the engine is warming up. The catalytic converter will also need to be tested to troubleshoot code 431.
Code 455 is for a leak in the evap system which is what vents the gas tank to the vapor canister. The system will need to be pressure checked for leaks and then repaired.
Keep in mind, once the repairs are made and the codes erased, the car will need to be driven at least 100 miles in various conditions before you re-test.

How to Diagnose a P0135 -Heater
Performance Bank 1 Sensor 1 (GM 3.5L)
January 31, 2012 Updated: October 29, 2014 Written by: Abraham Torres-Arredondo Article Id: 371

image_1.gifIf your check engine light is on and you have a diagnostic trouble code P0135 stored in the PCM's memory... then you've come to the right place to test and troubleshoot the upstream oxygen sensor.
A P0135 DTC says: HO2S Heater Performance Bank 1 Sensor 1... and this means that the PCM (Powertrain Control Module = Fuel Injection Computer) has detected a problem with the front oxygen sensor's heater element or a problem in the heater's circuit (wires).
In this tutorial, I'll show you how to check the oxygen (O2) sensor's heater element and the two circuits that feed it with power (10 to 12 Volts) and ground with a multimeter.
In case you're wondering, where the oxygen (O2) sensor that the code P0135 is accusing of being BAD is... this bad boy is located on the exhaust manifold and before the catalytic converter.
To help you navigate this article, here are its main points:

  2. What Tools Do I Need to Test Code P0135?
  3. What Does the Heater Inside the Oxygen Sensor Do?
  4. Circuit Descriptions of the Downstream Oxygen Sensor.
  5. Start Here.
  6. TEST 1: Oxygen Sensor Bank 1 Sensor 1 Test.
  7. TEST 2: Checking 12 Volts to O2 Heater.
  8. TEST 3: Checking the O2 Heater's Ground Circuit.
  9. TEST 4: Ohming the O2 Heater Element.

    Given that most of the trouble codes are for the O2 sensor, I think I would change it. The multiple misfires could be because of improper fuel/air mixture caused by a bad sensor. Disconnect the negative(-) battery terminal then change the sensor. Disconnecting the negative(-) should reset the computer and allow the fuel/air mixture to return to default allowing the engine to start.

    I got code P1135 in 01 toy 4runner. I have replaced the o2 bank 1 sensor (A/F sensor) and also the map sensor. On my scanner I read a 3.298 volts at all times! I even unplugged the sensor and it still...


    P1135=Air-Fuel Sensor Heater Circuit Response Malfunction,
    This code does not identify a particular o2 sensor,
    did you get a code that showed a fault leading to the one you replaced?
    Have you checked the voltage in the other o2 sensors to compare.

    P0155?


    P0155 OBDII code refers to HO2S heater circuit - bank 2 sensor 1 , not knowing your engine size and engine vin code thats about as far as we can go with our answer . we can say bank 2 sensor 1 is the passenger side upstream oxygen sensor has a heater circuit problem , could possibly be a bad oxygen sensor . you ask what is that - thats what it is ... cheers .
