hey yall.. about 4 days ago i bought 2 o2 senors.. both bank 2. replaced them both. went to autozone the next day and ran it. said that one of the senors i put in had low voltage but the other was fine. went out the next day and bought a another sensor for bank 1 sensor 1. ( this was also bad)ok.. went to autozone tonight and it said bank 2 sensor 2 was no activity, bank 1 sensor 2 was no activity and there were 2 other ones that said oxygen sensor circuit was no activity. or something like that.. basic story is that i replaced 2 bad 02 sensors in bank 2. had it checked, 1 of the ones i replaced was good. changed another sensor in another bank.. now they are all screwed.. wtf is going on? any help would be awesome. thanks you all. also, the scanner said i had %26quot; random multiple misfires%26quot; is this all the same problem?
I think o2 sensors bad and misfire?
take it to the dealer to have the pcm programming updated with software for 02 sensor failures and replace the fouled plugs. also may have intake gaskets leaking vacumm

check main fuses under hood sounds like computer is not getting signal
The o2 sencer get the blame for alot of things that goes wrong with the car. remember those sencers are at the end of all the rest. you need to look a little farthere in to all the sencers the ramdom miss fires could be the coil packs if you have them or the dist. if you don't. Some thing is telling the computer the wrong info. and this is what you got to find. the sencer may still work but giving the wrong info like the engine is cold and it really warmed up so you won't get a code for that.
Fix the multiple missfire code first. Bet it cures all your problems. Just because you have an o2 sensor code don't mean the sensor is bad. Just means it has read rich or lean for too long to suit the computer. the missfire can cause it to read rich because the fuel is not burning in the cylinder and dumping raw fuel in the exhaust. So the 02 sensor reads that as a rich burn and sets the code.

I need an oxygen sensor on my 99 ford ranger xlt. Is it hard to get to or is it inside the manifold?
It's a 4 wheel drive, 4.0 litre, 6 cylinder. If it's easy to change I'll do it myself. If not, I'll take it to a mechanic.
I need an oxygen sensor on my 99 ford ranger xlt. Is it hard to get to or is it inside the manifold?
It depends on which one one. There are FOUR. The only tool you need, is either an O2 sensor socket, or an open end 7/8%26quot; or 22mm size wrench. Hope this helps.

Well, Rakel is right (like always) but why are you changing the 02 sensor? If it due to an autozone diag, just go throw the money in the street. There are many, many things that can cause a 02 to read wrong, and until it is diagnosed correctly, you might just be wasting $80.00 at a time till you get the correct one replaced, not to mention the skin that will have to grow back. And I would recommend to do it on a cool engine, the pipes can be very unforgiving.
Hope it helps....
pretty much agree with the other two except I own a 2 foot long screw driver so I can depress the o2 sensor locks on the connector if it's ones buried in there... most I use a 7/8 inch wrench with no problems to remove
Take it to a mechanic,4.0 lt engines are not easy to work on,been ther done that.Good luck

Best Check Engine Light Scanner for 1999 Ford Explorer?
I been checking my codes with the Auto Zone OBD scanner and I was told that it does not provide the exact codes for my 1999 Ford Explorer. I had oxygen sensors codes show up when I used the Autozone scanner and I've changed the sensors twice. Would anyone know which Check Engine light scanner is best for my 1999 Ford Explorer? Also, I've only found three sensors under my car two near the engine Bank 1 and bank 2. and the other before the Catalyst converter. I was not able to locate the fourth bank 1 oxygen sensor. can someone tell me where its at?
Best Check Engine Light Scanner for 1999 Ford Explorer?
On a V-6 or V-8 engine youshould only have three O2 sensors. One on each pipe or exhaust manifold coming out of the engine and one after the catalytic convertor.
Most O2 sensors will outlast an enigne or go 100K-200K miles. There are many things that can give a false reading to make it read an O2 sensor.
If you do not stay on top of oil changes or tune ups or there is significant oil usage from wear and tear these mechanical and chemical changes (dirty nasty oil) will give false O2 sensor readings.
Best ot have a full engine diagnostic to get the whole picture before spending anymore money on parts you don't need.
Good Luck!

YOU SHOULD GET THE VEHICLES COMPUTER SCANNED AND CHECK FOR ANY PROBLEMS AS WELL AS CODES AND THEN YOU WILL HAVE A GOOD IDEA ON WHAT THE PROBLEM TRULY IS.
TRY FINDING AN INDEPENDENT SHOP INSTEAD OF THE DEALER OR A CHAIN STORE BECAUSE YOU WILL BE OVERALL MORE PLEASED WITH THE FINDINGS AND THE SERVICE.
LEAVE IT THERE WITH THEM SO THAT THEY CAN FIND THE PROBLEM FOR YOU, IT WILL BE A LOT BETTER THAN JUST REPLACING PART AFTER PART AND NOT DOING ANY GOOD.

Where is the Oxygen Sensor on a 1995 Buick Skylark GS?
After 104,000 miles, my %26quot;Service Engine Soon%26quot; light is coming on intermittantly and I suspect it's the oxygen sensor which has never been replaced. If I can change this myself, I will. I'm having a problem finding it though. This car has a 3.1 V-6. Thanks.
Where is the Oxygen Sensor on a 1995 Buick Skylark GS?
i mechanic for a living,,and it sort of towards the back on this one ,its not out in plain site like most of them,,you can do better ,getting this one from the bottom of the car,,if you get in under it you,ll see it, it mounts right before the header pipe connects to the cat,on it,,be sure and soak it with with some wd-40 this will help bring it out,good luck,hope this help,s
Where is the Oxygen Sensor on a 1995 Buick Skylark GS?
Usually between the engine and catalytic convertor.
just beneath the headlights to the right of the do-hickey thingy and kitty korner from the widgity whatsamacallit.
On any engine the oxygen sensor or sensors are always on the exhaust between the manifold and the cat converter. You have a V6 so you're gonna have two of them. They're easy to spot because they look kinda like a spark plug only with a regular looking wire coming off of it. Dodge Man is right though. Soak them with a penetrant to loosen them.
It's most likely on one side of the engine exhaust manifolds. It might be covered with a heat shield. Or if not, it probably would then be towards the center of the exhaust system further down from the engine under the car screwed into the exhaust pipe.
But I would have the engine codes read first to determine what the computer is saying the problem is. Remember that the computer uses the o2 sensor to detect problems, so if the computer indicates that the o2 sensor is detecting a lean or rich condition it's probably another part on the car that would be making the exhaust not meet the requirements of the emission control system. (most auto parts sales people like to sell o2 sensors to people who know nothing about the car because it's easy to convince you that you need one, and for 50 or more dollars it might be worth looking further into the problem)

Oxygen sensor for a 98-99 toyota avalon?
I have a 99 toyota avalon and the check engine light just came on, I have no idea what is wrong, but the engine is fine. My friends told me that it might be my oxygen sensor. I read on some sights that my car has 2 sensors. I am kind of low on cash and I just want to change the one that is broken, how do I test it and where is this stupid sensor. Do shops tests check engine lights for free, since I might be doing that, also is it hard to fix?
Oxygen sensor for a 98-99 toyota avalon?
Hello and good question...
First off you will need to find out what the actual codes are that turned on the Check Engine Light. No point in waisting time and money fixing things that you or your friend might think is the problem.
All Check Engine Lights come on for multiple reasons and you will need to figure out WHY it came on. By having the codes you are narrowing down the location of the problem, so that you can use correct judgment and diagnostics to correct it with lower cost to you.
Go to your local auto parts store barrow their Code Scanner - now you will get a code or codes that lead you to the direction of the problem BUT may still not be the right solution.
Once you get the codes and you have an idea where to start your diagnostics , you will still need perhaps tools to do this.
I for one would do this, since you are not able to correct the problem without tools and/or/ scanner - I would go to the Dealer have them run diagnostics , get the info they give you fix the problem yourself. This way you have correct information on why the light is coming on and they have done all the diagnostics for you. You will pay something for this diagnostics but you can be sure that you will get the problem fixed.
Good Luck

Don't go guessing %26amp; replacing parts your car may not need. See if there is an auto-zone or pep-boys shop around, usually they will pull the code(s) from your computer for free, with the thought that they can sell you the part right then and there. However do not buy the part just because there is a code stored for it, there may be a wiring issue causing the code. There a probably about 160 different items that can make your check engine light come on, even a loose or missing gas cap will do that. Have the code pulled, go to alldata-diy.com, you can buy a subscription to all the technical data for your vehicle there so that you can acess the manufacuturers test for the specific code and/or a possbile service bulliten issued from the factory relating to your problem. It will also contain the nec. repair info once you determine the cause of failure.I think the subscription will run you about $ 25.00 for the year. Good Luck!
Before you do anything, take the car out and put the petal to the metal. I mean really floor it getting onto the freeway. Many times an O2 sensor will show bad because of carbon build-up. Most people occasionally put the petal to the metal a few times during the year, but with gas prices being high I have seen a lot more of these because people just don't run the car hard enough or often enough to keep it clean.
If this works for you be sure to give me best answer because I'll never get it in the voting!

Is air fuel sensor oxygen sensor?
we changed the primary oxygen sensor for Honda accord LX 2000, and the engine light came one again, this time the error code read%26quot; air fuel sensor%26quot; is this air fuel sensor the secondary oxygen sensor by the catalyst converter?
Is air fuel sensor oxygen sensor?
the air/fuel sensor can also be referred to as the oxygen sensor.
the LX 2000 has 2 opxygen sensors.
one is before the catalytic converter and the other is after.
a code scanner would narrow down which one is acting up.
However, replacing both is usually a good rule of thumb.
OR.. you have another problem, like maybe a broken vacuum line, which is allowing air into the system without the computer's knowledge and that could be affecting the o2 sensor's readings.
Is air fuel sensor oxygen sensor?
With a four cylinder engine, the code definition should have read: B1S1 (for the upstream sensor responsible for fuel/air ratio monitoring) or B1S2 (for the sensor downstream of the catalytic converter, which only monitors that part). If you changed the front (S1) sensor and you still have a code for it, save your old sensor as there may be nothing wrong with it. If the code is for the O2 sensor heater, check your fuses. If not, the code is probably a symptom of another problem, such as a misfire, restricted fuel filter or intake air leak. Is this the same code you got previously? Did you install a direct-fit replacement or a universal sensor that had to be configured for your honda's wiring connector?
May help you a little
there's should be two of them before and after the catalyst converter

Where is the Oxygen Sensor located in 97 Honda Accord?
The Check engine light came on and we had it checked out and they guy said we need to replace the o2 sensor..We have a 97 honda accord. Where would the sensor be located on my car and how do we change them? Is it something simple we can do or do we have to take it to the shop?
Where is the Oxygen Sensor located in 97 Honda Accord?
There are two (on 4 cyl) - one before, and one after catalytic converter. You need a special socket to replace it but first I suggest you determine which one is bad by checking the code number.
Oh, those parts store guys that tell you that an O2 sensor is bad but don't mention that there are more than one. Don't get me started!
