Here are the reasons for that code:

HO2S no. 1 heater circut is open or shorted
HO2S no. 1 is defective
Defective ECM

Using a scan tool, read freeze frame data. Freeze fram data records engine conditions when a malfunction is detected.

Access ECM behind glove box. Turn ignition on. Using DVOM, backprobe ECM harness connector. If DTC P0135 is set, measure voltage between ground and terminal No. 3 (Blue/Black wire) at ECM harness connector E10. If DTC P0155 is set, measure voltage between ground and terminal No. 4 (Yellow/Red wire) at ECM harness E10. Voltage should be 9-14 volts at each terminal. If voltage is as specified, replace ECM.

If not, Disconnect suspect HO2S No. 1 harness connector. Measure resistance between terminals B+ (Black/Yellow wire) and HT (Blue/Black wire on bank No. 1 ; Yellow/Red wire on bank No. 2) at HO2S connector (component side). Resistance should be 11-16 ohms at 68 degrees F and 23-32 ohms at 1472 degrees F. If resistance are not specified, replace appropriate HO2S. If resistance are specified, Repair wiring between ECM and appropriate HO2S, or between appropriate HO2S and EFI main relay (Black/Yellow wire at HO2S and Red wire at EFI main relay)

SOURCE: diagnostic code p0135

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.
Buying a Digital Multimeter for Automotive Diagnostic Testing (found at: easyautodiagnostics.com).

    1. Don't have one?... check out my recommendation: Abe's Scan Tool Recommendation.
  • Wire Piercing Probe.
    1. Although this tool is not an absolute must, if you do buy one, you'll realize just how easy it makes testing the voltages inside the wires.
    2. If you need to see what this tool looks like, you can see it here:Wire Piercing Probe.

    P0135 diagnostic code


    code P0135 is : O2 sensor heater circuit bank 1 sensor 1
    yes if sensor tell pcm that air/fuel mixture is lean and the pcm try to make it richer. At max it could stall engine .
    but think if there is more to it like spark plug, injectors clean

    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.
