    Further searching the Internet, I came up with the same conclusion. Thanks for confirming the location of the sensor. Apparently when Midas changed the muffler from the front manifold connection last week they may have used heat to loosen the bolts and the heat damage the sensor. I will buy a sensor tomorrow and replace it. Thanks once again.

What engine is in this vehicle? I assume the avalon would be a 3.0L or similar V6 engine. Bank 1 sensor one indicates one of the primary O 2 sensor controlling a/f ratio. Sensor one bank one would be the sensor located in the Front manifold, closest to the engine. Hope this solves your issue. I would first check the conector at this sensor for corrison before buying a new sensor.

Have a Ford fusion 06 Have p0141 code I fix the oxygen sensor but the codes still comes on?


Did you replace the right one ? This code does not necessarily mean the O2 sensor is bad . The code description say O2 heater " CIRCUIT " bank 1 sensor 2 Did you check the wiring , the fuse ?
P0141 - O2 Heater Circuit (Bank 1, Sensor 2) Description: See the description for DTC P0135. Possible Causes: See the possible causes for DTC P0135. Diagnostic Aids: See the diagnostic aids for DTC P0135. Application Key On Engine Off Key On Engine Running Continuous Memory All GO to Pinpoint Test DW . P0135 - O2 Heater Circuit (Bank 1, Sensor 1) Description: During testing the heated oxygen sensor (HO2S) heaters are checked for open and short circuits and excessive current draw. The test fails when the current draw exceeds a calibrated limit or an open or short circuit is detected. Possible Causes:
  • Vacuum hose disconnected on exhaust gas recirculation (EGR) system module (ESM) applications
  • Short to VPWR in the harness or HO2S
  • Water in the harness connector
  • Open VPWR circuit
  • Open GND circuit
  • Low battery voltage
  • Corrosion or incorrect harness connections
  • Damaged HO2S heater
Diagnostic Aids: Check the HO2S electrical connector for damage, corrosion, and water intrusion.

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.

    What is diagnostic procedures for DTC p0135 & p0141


    Oxygen Sensor problems... P0135 (Bank 1, Sensor 1) and P0141 (Bank 1, Sensor 2)

    P0135 - Oxygen O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)
    This code refers to the front oxygen sensor on Bank 1. The heated circuit in the oxygen sensor decreases time needed to enter closed loop. As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it.

    The ECM tracks how long it takes for the oxygen sensor to begin switching. It the ECM determines (based on coolant temp) that too much time elapsed before the oxygen sensor began operating properly, it will set P0135.

    Symptoms: You will likely notice poor fuel economy the illumination of the MIL.

    Causes: A code P0135 may mean that one or more of the following has happened:
    O2 Heater element resistance is high
    Internal short or open in the heater element
    O2 heater circuit wiring high resistance
    open or short to ground in the wiring harness

    Possible Solutions:
    Repair short or open or high resistance in wiring harness or harness connectors
    Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)



    P0141 - O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)
    This code means that the heated circuit in the oxygen sensor on bank 1 decreases time needed to enter closed loop. As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it. The ECM tracks how long it takes for the oxygen sensor to begin switching. It the ECM determines (based on coolant temp) that too much time elapsed before the oxygen sensor began operating properly, it will set P0141.

    Symptoms: You will likely notice poor fuel economy the illumination of the Check Engine Light.

    Causes: A code P0141 may mean that one or more of the following has happened:
    open or short to ground in the wiring harness
    O2 heater circuit wiring high resistance
    O2 heater element resistance is high
    Internal short or open in the heater element

    Note: Typically a failed catalytic converter does not cause this code. You're more likely to see a P0420 code for a failed converter.

    Possible Solutions:
    Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)
    Repair short or open or high resistance in wiring harness or harness connectors

    I'm thinking about buying a 2002 range rover. It has a service/check engine codes of 134,135,155. Is it likely to be more than oxygen sensor problems? Please reply , Mel


    with those codes showing, it could be either bad O2 sensors or there is a problem with the wiring to those sensors. Also, the wrong sensors may be installed. I'm assuming codes P0134, P0135, P0155.

    For others viewing this:

    P0134 = O2 sensor circuit-no activity detected (bank 1 sensor 1)

    P0135 = O2 sensor heater circuit malfunction (bank 1 sensor 1)

    P0155 = O2 sensor heater circuit malfunction (bank 2 sensor 1)

    I have a gmc envoy & the trouble codes are p0107,p0130,p0135 & p0171 can you tell me what the problem can be.


    P0107 Manifold Absolute Pressure/Barometric Pressure Circuit Low Input

    P0130 02 Sensor Circuit Malfunction (Bank I Sensor 1)

    P0135 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)

    P0171 System too Lean (Bank 1)

    Check your Manifold Absolute Pressure Sensor, and it might be a good time to install a new Upstream O2 Sensor.

    It might also be beneficial to have your fuel pressure checked if the engine is really running Lean, but this may be caused by a faulty O2 sensor.
