If u know u have a bad o2. I guess u must have used a scanner or equivalent. There are 4 o2s on LHS. The way u can tell the difference is by the # sequence that the failure code is giving u. For example the o2s on the right side are even # on the left odd #. Pre cat is 1 after cat is 2. So if u have bad 2/2 Than u know it's right rear or a bad 1/1 is left front ect ect. First make sure u have the right code. With out a scanner. it can be done with a volt meter or a vantage, but it's a heck of a lot easier pulling the codes.

Where is the oxygen sensor located for nissan sentra lec


this is from the web, yahoo answers I think




Best Answer: That was the dumbest answer. On a four cylinder engine a o2 sensor is reading the air fuel ratio from the exhaust of all four cylinders. There is a o2 sensor before and after the catalytic converter. Bank 2 is refering to the o2 sensor after the cat. When u replace it you need to inspect the cat and make sure its not coming apart from the inside. If it is you need a new one. If u cant afford one then i would just hollow out the cat with a large screwdriver. If u hollow it out ur car wont pass emission testing.

I have a 1997 ford explorer sport we have put on several different computers said oxygen se?ors bank one and 2 bad my mechanic put in turn check engine light on came right back on after I drove 30 sec...


You need to take it to someone who knows what's up . Can have a problem that sets a o2 sensor code an be something else ! Need to put on a scan tool an see if O2 sensor is rich or lean ! What code did it set ? Did your mechanic check fuel trims ? Could have vacuum leak , leaking fuel injector . You never go by just the codes , usually they point you in a direction to test ! An it's real nice to have the scanner like this guy uses ! Ford O2 Sensor Testing

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.

    Removal & Installation

    3.5L

    WARNING When disconnecting the sensor electrical connector, do not pull directly on wire going into sensor.

    1. Disconnect the negative battery cable.
    2. Disconnect the heated oxygen sensor electrical connector.
    3. Use a socket such as a crowfoot wrench to remove oxygen sensor.

    To Install:

    NOTE When replacing an O2 Sensor, the PCM RAM memory must be cleared, either by disconnecting the PCM C-1 connector or momentarily disconnecting the Battery negative terminal. The NGC learns the characteristics of each O2 heater element and these old values should be cleared when installing a new O2 sensor. The customer may experience driveability issues if this is not performed.
    1. After removing the sensor, the threads must be cleaned with an 18 mm X 1.5 + 6E tap. If reusing the original sensor, coat the sensor threads with an anti-seize compound such as Loctite 771- 64 or equivalent. New sensors have compound on the threads and do not require an additional coating. Tighten the sensor to 28 Nm (20 ft. lbs.) torque.
    2. Connect the heated oxygen sensor electrical connector.
    3. Install the wiring clip to the heat shield.
    4. Connect the negative battery cable.

    3.8L Downstream Sensor

    WARNING When disconnecting the sensor electrical connector, do not pull directly on wire going into sensor.
    1. Disconnect negative battery cable.
    2. Raise and support vehicle.
    3. Disconnect the electrical connector.
    4. Use a socket such as a crowfoot wrench to remove oxygen sensor.

    3.8L Upstream & Downstream Sensors

    NOTE When replacing an O2 Sensor, the PCM RAM memory must be cleared, either by disconnecting the PCM C-1 connector or momentarily disconnecting the Battery negative terminal. The NGC learns the characteristics of each O2 heater element and these old values should be cleared when installing a new O2 sensor. The customer may experience driveability issues if this is not performed.

    2. Connect the heated oxygen sensor electrical connector.
    3. Connect the negative battery cable.

    3.8L Upstream Sensor

    WARNING When disconnecting the sensor electrical connector, do not pull directly on wire going into sensor.
    1. Disconnect negative battery cable.
    2. Disconnect the upper O2 sensor connector.
    3. Use a socket such as a crowfoot wrench to remove oxygen sensor.

    Testing


    NOTE Allow the O2 Sensor to cool down before conducting the test. The O2 Sensor voltage should stabilize at 5.0 volts. Raising the hood may help in reducing under hood temps quicker.

    1. Turn the ignition on, engine not running. With the scan tool, actuate the O2 Heater Test.
    2. With the scan tool, monitor O2 Sensor voltage for at least 2 minutes. Does the O2 Sensor voltage stay above 4.5 volts- If so, sensor is normal.
    3. If voltage does not stay above 4.5v as indicated, check wiring and connectors. Check O2 sensor for contamination.
    4. If wiring from the O2 sensor is damaged, DO NOT repair it; replace the O2 sensor.
    5. Turn the ignition off. Allow the O2 sensor to cool down to room temperature.
    6. Disconnect the O2 Sensor harness connector.
    7. Measure the resistance across the O2 Sensor Heater element component side. Resistance for either O2 Sensor should be 2.1-2.7 ohms.
    8. If the O2 Sensor is not within range, turn the ignition off.
    9. Disconnect the O2 Sensor harness connector. Turn the ignition to ON; engine not running.
    10. With the proper scan tool, actuate the O2 Heater Test.
    11. Using a 12-volt test light connected to ground, probe the O2 Heater Control circuit in the O2 Sensor harness connector.
    12. If the test light illuminates brightly and flashes on and off, replace the O2 Sensor.
    13. Confirm the repair with the appropriate Verification Test.
    14. Turn the ignition off.
    15. Disconnect the O2 Sensor harness connector.
    16. Disconnect the PCM harness connector.
    17. Measure the resistance between ground and the O2 Heater Control circuit in the O2 Sensor harness connector.
    18. Is the resistance below 5.0 ohms- If yes, repair the short to ground in the O2 Sensor Heater Control circuit. If resistance is okay, go to step 20.
    19. Confirm the repair.
    20. If resistance was okay when measured in step 17, check the PCM harness connector terminals for corrosion, damage, or terminal push out. Repair as necessary.
    21. If the resistance is still not within specified range, replace and program the Powertrain Control Module in accordance with the service information.
    22. Confirm the repair.

    How do you know which o2 sensor is bank 1 sensor1


    sure do. the bank 1 sensor 1 oxygen sensor is located in the exhaust pipe on the same side as the number 1 cylinder. So if the number 1 cylinder is on the driver's side, then the bank 1 sensor will be the forward most oxygen sensor on the drivers side, then next one in line will be the bank 1 sensor 2. Obviously, the other side will be bank 2, sensor 1 and bank 2 sensor 2.....good luck!

    Replacing oxygen sensor


    the sensor can be tested but it requires a very expensive electronic system scanner, what code do u have, most O2 codes are not a fualty sensor but a problem in the fuel injection system, the sensor just reads the problem(s)

    Oxygen sensor replacement


    It's something you can with simple tools, you have four O2 sensors. Your going to have to get the truck rescanned or if you have the DTC code, you can find out which O2 sensor has gone bad so you can replace it. Your going to have Two upstream O2 sensors on each exhaust bank, one O2 sensor before the Catalytic Converter, and the last one after the Catalytic Converter. Its like replacing a Spark plug and you can pick up the O2 sensor at any large Auto Parts store with a can of WD 40. Just unclip the wire leads to the O2 sensor and then with a O2 sensor socket or hint close end wrench and hammer, you can remove the O2 sensor from the exhaust pipe. Good luck and be safe.

    I am having problems with the oxygen sensor on my 1997 chevy silverado ? I cant seem to find the sensor ?? Does anyone know where it is at and how to change it out ? Also will the oxygen sensor cause the...


    your o2 sensor is located on your exaust. You have either two or four, I think their is only two on a 99 chevy if I remember correctly, pre catalyst and post catalyst. This means one before your catalytic converter and one after. The pre is usualy the culprit but they will not stop your truck from cranking over. This sounds more like a battery,battery cable, or starter problem. Hope this helps, Clay
