Oxygen Sensors

Also called as the lambda sensor, an oxygen sensor measures the proportion of oxygen in liquid or gas. Scientists use this electronic device in measuring respiration or production of oxygen. Oxygen sensors are also used in automobiles.
  == oxygen sensors ==   The Ford Focus has two Oxygen sensors, one before the catilitic converter, one after. The one before the catilitic converter is easy to see. When you open the hood, its all the way foreward in the center.
  == Answer ==   Have vehicle scanned to determine problem and reset
It is screwed into the exhaust manifold behind the engine.
The only real way is to take it to a garage and get them to check the exhaust emissions. This only takes about 5 minutes and my local garage didn't charge me for this when I did this.If the emissions are NOT OK, then this could point to problems with the fuel injection system as well. If the...
They are screewed into the exhaust pipes. There will not be any after the muffler.
that is the oxygen sensor on the exhause manifold.
 == Answer ==   Some modern cars like the maxima even have four O2 sensors. The reason some cars have more than one O2 sensor is to be able to moniter the level of unburnt hydrocarbons that are present before the catalytic converter and the level present after the catalytic converter, this is...
How many oxygen sensor on your 1999 3.5 rl?
You really shouldn't have to reflash it. Reflashing is a process that basically erases everything on the computer, and then reprograms it. In order to reset the "Service Engine" light, you should be able to disconnect the negative side of the battery for 15-20 minutes and then reconnect it.
  In the exhaust manifold or downpipe
Unplug the sensor and unscrew it from the exhaust pipe. You'll probably need a special socket to do it without damaging the wires.
It will usually come on. The speed sensor on my transmission died and it displayed the check engine light.
    == Answer ==     In 2004, the Dodge Cummins Diesel was not equipped with an oxygen sensor. The 2007.5 and newer Cummins 6.7 liter Bluetec diesels have an O2 sensor in the downpipe. Typically, only particulate filter equipped diesels have O2 sensors.
It threads into the exhaust manifold on the back of the engine.
A 7/8" combination wrench. Unplug wire harness to sensor, cut wires off at sensor, slip 7/8"box end over sensor, turn counterclockwise and remove. Install using the open end of 7/8" combination wrench, reconnect harness.
Get a special cut out socket that allows the wire to stick out without damage.
  == Answer ==   only the engines with computers and electronic controls  
Unbolt from the block & take the nuts off studs to exhaust flange. You will need a new gasket for the block & a new one for the flange.
  == Answer ==   They are screwed into the exhaust system.
%DETAILS%    == Answer ==   Have you replaced any tail light or turn signal bulbs lately? It is a common mistake to replace a combinaton turn signal/tail light bulb with the wrong one. I ran into this problem on an older buick. I replaced a bad turn/tail bulb with the wrong bulb. The new...
  == Answer ==   There is an oxygen sensor right on the exhaust manifold, directly behind the radiator and fan. Follow the spark plug wires down from the top of the motor. From where those wires plug into the coils, go left (assuming you're standing in front of the car ;P). The sensor is the...
I would say the air has the highest level of oxygen but it depends how high up you are.
  == Answer ==     It all depends on the size of the engine, but there should only be one.
Bank one is the drivers side of the engine. Sensor 2 will be the second sensor that's screewed into the exhaust pipe away from the engineon that side.
Answer . After the exhaust manifold but before the catalytic converter on the exhaust tube.
A thread chaser. Your local auto parts store can sell you one.
Oxygen, on earth, is a gas because it is in a gaseous state. On mars, it is liquid. The physical state of any element like hydrogen, nitrogen, oxygen, sodium, sulfur, etc depends on the ambient temperature and pressure. The earth's atmosphere doesn't pressurize oxygen enough for it to turn into a...
  == Answer ==   I just got told there were 2 sensors by shop fixing my 2001 VW Jetta V6, one in front and one behind the engine.     Shop said they cost $80 a piece. Apparantly this is cheaper than a lot of other sensors for foreign cars ($200+ for BMW and Audi?) because the VW...
  == Answer to Oxygen sensors question ==   Mercury Mystique with V6 engine has two oxygen sensors. First one located between radiator and engine, second - behind the engine, near the coil pack (below). It's not very difficult to replace them.
  follow the battery negative cable to it's other end and, voila, there is your ground.
Bank 1 is the passenger side of your engine , sensor 1 is before the catalyticconverter ( upstream ) on your Ford F-150
They should be in the exhaust system close to the engine ( either in the exhaustmanifold outlets or theexhaust pipe ) before the exhaust enters the catalytic convertersBank 1 is the passenger side of the engine and sensor 1 is the upstream sensorBank 2 is the driver side of the engine and sensor 1...
2 one by the oil filter (upstream) and the other is on the cat converter, best price is on E Bay, Bosch 13550 thin k is the part number for the one up frnt
  == Answer ==     you have to pull the entire toliet up. Then hopefully the bolts are all that are rusted. the metal (or plastic) flange the toliet carriage head style bolts run into, may be bad also. If this is the case, you will need a plumber, or elevate yourself to a higher degree...
there are 2 oxygen sensors on this car. the first is on the front of engine where it is mounted in the exhaust monifold. the second one is on the exhuast pipe right next to the cat. converter. you can't miss em, they stick out about 2 inches, and there is a wire connected.
where is bank 2 sensor 1 in a 2001 ford taurus ses 6 cyl
read the manual of the sensor kit.. how hard could it be
    == Answer ==       Check to see if the thermostat is stuck open also check for binding brakes.dirty or clogged fuel injectors.   == Answer ==     Also check the air filter.
It is installed on the top of the back side exhaust manifold.
  == Answer ==   There are two oxygen sensors.  One located on the exhaust manifold and one located after the catalytic converter.
NO. there 2 different things / sensors.
%DETAILS%    == Answer ==   actuall, it may depend on the engine you have. on the 3.3 there are 4! one on each side, fairly easy to get to, in the collecter area of the exhast manifold. another on each side after the small catalytic convertor, and before the two pipes come together.these are...
Answer . \nThere is no such thing as an "odometer sensor." There is a vehicle speed sensor that is located on the output shaft housing of the transmission. That sends info to the speedometer. From there, the speedometer and the odometer are both operated internally, so if your speedo is working,...
I don't know the cost of the sensor but it is just a mamtter of unplugging the old one, unscrewing it and installing the new one. GoodluckJoe
I have a 1996 Firebird and it has 4. Two in the manifolds and one before the catalytic converter and one after.
Answerbuy a new oneIf your D4 button is blinking along with your speedometer not working then it might be your VSS (vehicle speed sensor) that is out. You can get another one from the junk yard fairly cheap however this is a common problem so I would highly suggest you purchase a new one to avoid...
Oxygen Sensors? Well, up to four.....2 on the manifolds, and at least 1 on the straight exhaust pipe. Very expensive....Parts $2700Who in their right mind (or left for that matter) would spend $2700 for 4 oxygen sensors????? Try goint to advance auto online and put the 4 O2 sensors in your cart. Use...
The O2 sensor bank 1, sensor 2, on a Dodge Ram 1500 pickup truck,  can be changed by first removing the air intake line. Next, remove  the retaining screws. Reverse the process to install the new  sensor.
it refers to the location of the oxygen (o2) sensors relative to the engine. The upstream sensor is the one closest to the engine. The downstream sensor is furthest from the engine. Think of it as the way a stream of water, or in this case, a stream of exhaust flows.... From the engine To the...
  == Answer ==     The catalytic converter is probably doing all the work. There may be no need to recirculate the exhaust gases.     ed724
You need a special socket that can bought at Murray's or a similar auto parts. The wiring fits through it so you can get to the bolt. The socket cost about $8.
There is 2, one before and one after the catalytic converter.
Exhaust system. Usually manifold near port(s).
  go under your car and there you should see the exhaust pipes running towards the back. they are both next to each other, and the oxygen sensors are screwed directly into the exhaust pipes. usually there is 4 of then. on both pipes, one is for the upward oxygen flow and the other for the...
The 02 sensors are in the exhaust pipes but don't know about the updraft sensors.
Yes as long as you use the right on for your emissions, California or federal
  == Answer ==   hey dude call up advance auto parts and give them the code and they will look the code number up in the book. i know it because i work there and use the book everyday. goodluck   Answer    I own an 89 Dodge Dakota and from my experiences and research the reason that...
Upstream oxygen sensors send a signal to the PCM which adjusts the fuelmixture ( air / fuel ratio )
On 1990, 302 V8 model, the sensors are located just aft of the exhaust headers and on a line where the gearbox joins to the rear of the engine and where the exhausts start to run down the body. You need to get under the car, they are just above the floor pan line. The two sensors have two white...
One, it is located usually just underneath the #5 spark plug, bolted into the exhaust manifold, it will have a "pigtail" wire that connects it to the wiring harness, be careful here, you may have to jack the car up to access the pigtail's connector, as it is usually easier to get to it from there. ...
There are many symptoms of a bad O2 sensor. Some are poor fuel  efficiency, flashing check engine light, the failure to pass a smog  test, and rough idling.
  Black smoke is overly rich fuel/air mixture.   Blue smoke is oil burning.   White smoke is coolant in the combustion chamber.   I have never seen green smoke coming from an auto exhaust. The only thing I would suspect is that this is coolant in the combustion chamber caused by a blown...
I added a link for you to check out. Your car has O2 sensors to monitor the catalytic converter efficiency....one will be before the cat, the other after. If you gutted the cat then yes, it will always set a code. I have no idea if this can be programmed around. I would put a good high flow cat(s)...
The proper way to check the alternator, would be best if you remove it and take it to your nearest auto parts store. Most of them test them for free. As far as outside controllers?   I'm not a mechanic but as far as I understand it there are no controllers as the alternator is always running,...

== Answer ==   the sensor is located in the differential housing on the back of the transmission.   (this is the speedomoter sensor, it is in the housing that the pass axle shaft slides into)   == Answer 2 ==   For the 3.3/3.8L, it is near the bell-housing facing the firewall, as it...
If you went to school for the mentally challenged would you be considered a genius or would you be right at home??
Yes, if the leak is in the manifold or collector before the 02  senor.
By the emissions label that states that the vehicle is certified for sale in California,or the label states that it conforms to California regulations. usually located under the hood, or the radiator support, or on the firewall of the vehicle.
%DETAILS%    == Answer ==   try looking for the overide switch or auto lights and turn the other direction 
well, it's cheaper to change the sensors. but that wont fix it. you need precats. check eBay for best prices. they ain't fun to change, and if you don't have a lift, god help you
Left and right oxygen sensor not working.Toyota camry 6 cyl,1999
yeah mine gets about 50-100k's less than it should to a tank of gas thanks to a faulty 02 sensor, Toyota part number 89465-19685
    two, all metros from 1996 and up use the obd2 which has two,,,  
They are round and about 3 to4 inches long with an electric wire in the end of them and there screewed into the exhaust pipe system.
  == Answer ==     I'm a little puzzled by the wording of the question. I suspect that whoever told you this didn't explain your problem right, or maybe they didn't know whta they were talking about to begin with. The reason is that you are asking about two completely unconnected and...
It is located on the exhaust piping on the underside of the car just past the transmission and such. It is on the "up" side of the piping, making it slightly difficult to find. It will look similar to a spark plug and have 1 wire leading up from it.
  == Answer ==   In the exaust pipe down past the manifold
Bank 1 is the drivers side of the engine and bank 2 is the other side. Sensor 1 will be the first sensor that's screewed into the exhaust pipe where it bolts to the exhaust manifold. sensor 2 will be further down the exhaust pipe towards the converter. There are 2 in the pipes on each side of the...
Three. Bank 1, Bank2, and a down stream.
They are screwed into the exhaust pipe/pipes.
Wher are the oxygen sensors located on a 2001 rx300 Lexus SUV
Your model has two oxygen sensors. The first, called the precatalytic converter oxygen sensor, or precat, is located at the end of the exhaust manifold. If you look down between the engine and the firewall, you'll see your exhaust. The small plug with a wire leading back to the engine is your precat...
There are 4 oxygen sensors on the 2001 ford f150 v6.
Answer . It is a sensor placed in the exhaust flow that indicates the level of unburned fuel in the exhaust so the computer can adjust the air- fuel ratio
upstream sensor will be located before the catdownstream sensor will be located on the cat itself
This is a bolt-on part. I suggest you take it to a shop if it's not obvious to you.
I have a 1999 Nissan maxmia, the check engine light came on and i went to get a check on it and the computer said, bad or weak o2 sensor, i was wonder where i was s it located at. how long do i have to ride on it
== Answer ==   Here is the low-down on oxygen sensors, and their location designations explained:   Oxygen sensors are screwed into the exhaust system at various points. Some people say that there are 4 oxygen sensors, but technically, that is not correct. Only the front 2 are considered...
A Nissan Primastar is a rebadged Renault Traffic or Vauxhall/Opel Vivaro. There are three on the 1.9DCi (Renault F9X Engine), one after the manifold, one before/on the Catalytic convertor and one post catalytic convertor. ODBC Diagnostics will tell you which sensor failed. Typically P0042 - HO2S...
Bank 2 is the driver side of the engine on your Ford and sensor 1 is close to the enginein the exhaust before the exhaust enters the catalytic converter ( upstream )
Generally a Bad Oxygen Sensor will cause the engine to run too Rich...too much gas mixed with not enough air. This will decrease Gas Mileage, and lower the engine's performance. Also the Check Engine light will come on!
