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:
  1. Symptoms of a BAD Oxygen Sensor Heater Element.
  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.
  10. P0135 O2 Sensor Heater Test Summary.

    Engine code 28


    Are you sure it is a code 28? I only ask because my book doesn't show a code 28 in regards to this problem. I show codes 25 and 26 that may relate to this problem. But before replacing o2 sensor, there are other probabilities for this code showing up. They would be: Injector or injector circuit, Coolant temp sensor or circuit, Air temp. sensor or circuit, Airflow meter, Cold start injector, ECM (Electronic Control Module- THE BRAIN) Or the o2 sensor of course. Plz save your money before purchasing o2 sensor and check possible related items first.You may find o2 sensor is not at fault. Hope this helps.

    Yeah, you could do that. Bank 1 is always the engine side where the number 1 cylinder is located. Sensor 1 is the first sensor in the exhaust system, nearest the engine. Sensor 2 is always located farther downstream in the exhaust.

    The code that comes up is p0141. the book says that it is a O2 sensor heater malfunction. But the book does not show me where the O2 sensor heater is located. I'm confused. I have located the 02 sensors. 4...


    P0141 is O2 Heater Circuit (Bank 1, Sensor 2) It will be the sensor AFTER the cat on the side that has #1 cylinder. On your car it's the PASSENGER side.

    Had o2 sensor bank 2 # 2 replaced , 1 week later engine light is back on . where is this sensor located and why does this one keep going bad?


    It is possible that the sensor was not bad to begin with. Some times another problem will cause the O2 sensor to show a condition when all it is doing is what it is supposed to and a lot of guys will change it. I ran into this myself. I had a code so I had it read. O2 sensor showed a lean condition so the guy suggested I change it. Except it didn`t say which one and there were 4 of them. Didin`t make much sense to me. Turned out I had a bad lower intake gasket which caused the lean fuel mixture because of the un-metered air. All the sensor did was tell me the truth. It did its job. I know this don`t answer your question but this is where a good mechanic comes in and the sensor is located in the exhaust pipe close to the catalytic converter.

    Why would you need a diagram?

    You simply need to educate yourself

    O2 Sensors have been on vehicles over 25 years,and in the same place

    Sensor 1--in exhaust pipe before converter or in converter
    Sensor 2 in outlet of converter
