SOURCE: o2 sensor bank1 sensor 1

usually bank 1 sensor one is closest to the motor(guess) but you can look it up in a manual and just changing the 02 sensor is gonna fix it they are anywhere from 40 to 100 dollars hope it helps

SOURCE: 2003 VW Golf - O2 Sensor?

Honestly it is not very expensive to replace, but it is not extremely important. What it does is measure the oxygen/fuel level coming out of the engine. This tells the computer that the engine is either using the right air/fuel mixture or allows the computer to change the mixture slightly to allow the car to run properly. You could pull the sensor out and clean the terminal as it usually has alot of carbon build up due to its location, but this is normally a temporary fix. I hope this helps you with your problem.

SOURCE: location of the bank 1 sensor 2 O2 sensor on a 2001 ford escape

B1 means the sensor is located on the same bank of the engine that has the #1 cylinder. B2 is located on the opposite bank.
S1 means the sensor is located BEFORE the catalytic converter
S2 means the sensor is located AFTER the catalytic converter

You didn't say which engine you have, so I've included the diagrams of both 4 cyl and 6 cyl so you can see the banks

I would check the O2 sensor, and if it checks bad, replace it, and clear the trouble codes. If the light comes back on, you may need to check further. .

Hi, I am getting Faulty codes P0036, P0056, P0141, P0161 in reference Bank 1 and Bank 2 for sensors 2 on 2003 CTS.I was told the sensors where changed but codes still appear?


If the sensors were replaced an DTC'S come back has to be a wiring problem or PCM ,
The ECM detects that the HO2S heater low control circuit voltage is between 2.6-4.6 volts when the heater is commanded OFF, indicating an open HO2S heater circuit.
Is the fuse open?
All four codes refer to the heating element circuit ! there is a relay in the under hood fuse box that supplies B+ voltage to the O2 sensor heating elements . I would change that or test the relay , videos on you tube on testing relays .

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.

    Is p0052 a fuse problem or a o 2 sensor


    P0052 DTC trouble code may be caused by one or more of the following:
    A short in the heater circuit in the sensor.
    A failed O2 sensor heater.
    Wiring/connectors broken/frayed leading to sensor and/or relay.
    Failed PCM/ECM.

    Can't by pass as oxygen sensors control your fuel

    I suspect your exhaust converter has failed & the car has
    been running rich for years & ruined it

    Wouldn't your repair guy be able to solve all your issues,
    after all you were at a shop for some work

    Sounds like they sold some service instead of diagnosing
    the reason you were there

    The code is for the heater in the O2 sensor bank one sensor two. That would be the sensor after the catalytic converter on bank one.
    It could be the sensor itself or the power supply for the heater.

    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


    Hope this helps (remember to rate this answer)..

    Subaru wrx impreza showing fault code p0037. how do i fix this fault which sensor is it and where is the sensor located?


    http://helpforcars.net/obd_codes/codes.php?code=P0037

    It's an O2 sensor according to the above link, and it is bank 1 sensor 2 low, the 2 meaning that it is downstream past the catalytic converter but not on the manifold.

    - Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit open shorted to ground
    - Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit poor electrical connection
    - Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit
    - Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit fuse
    - Faulty Engine Control Module (ECM) Possible Solution Tech Notes The code means that there is a problem with the heater element circuit of the heated oxygen sensor. Water getting inside the heated oxygen sensor connector can caused the heated oxygen sensor fuse to blow, which is a very common problem for this type codes. Before replacing the sensor, check for the condition of the heated oxygen sensor fuse and connectors.
    Good luck on this repair.

    The check engine light produced codes p1150 and p1155 on a 2000 toyota avalon xls.


    All cars sold in the US after 1995 use the same on board diagnotics called OBD-II. The codes are the same. Search OBM-II error codes and you'll get a listing.

    P1150 Air/Fuel Sensor Circuit Range/Performance. (cylinder bank 1 Sensor 2)

    P1150 may mean that one or more of the following has happened:
    water or corrosion in the O2 sensor connector, loose terminals in the connector, wiring burnt on exhaust components, open or short in the wiring due to rubbing on engine components, holes in exhaust allowing unmetered oxygen into exhaust system, unmetered vacuum leak at the engine, bad O2 sensor or bad PCM.

    P1155 Air/Fuel Sensor Heater Circuit. (cylinder bank 1 Sensor 2)
    P1155 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 or O2 heater circuit wiring high resistance

    Solution :Replace oxygen sensor and see if the problem goes away.
