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.

Where is the oxygen sensor on a 1991 dodge dynasty?
It threads into the exhaust manifold on the back of the engine.
First the answer to your second question. "Generally" the stated life of the O2 sensor is 100K. When one goes bad, the 'check engine light' should come on and the diagnostics from that should tell you which one is bad. If your vehicle has at least 100K, then you get into the "might as well as" area-if one is bad, could the others be far behind?
Replacement on your vehicle does not normally require the special socket for O2 sendors.
The number one upstream sensor is located between the motor and firewall, the number two upstream sensor is located between the motor and radiator, and the downsteam is located under the car. Replacing number one upstream and the downsteam sensor both require jacking up the vehicle to work from underneath. Replacement of the number 2 upstream sendor can be done with just the hood up.
First, unplug the sensor from the wiring harness.
Second, remove with a 22mm boxed or open end wrench.
Third, compare your purchase with the sensor that has been removed.
Replacement is the opposite of removal, install with 22 mm wrench and plug in.
You may have to disconnect the battery to clear the check engine dash lite and code.
How do you replace the oxygen sensor on a ford expedition?
Oxygen Sensor There are actually (4) O2 sensors on your truck. If you look inside the wheel wells behind the fender liner, right about where the frame is one O2 sensor, the other is underneath the truck about half way back in relation to the transmission. If you see where the exhaust joints together, you went about 6" too far.
When you start looking at the O2 sensors, they are normally numbered something like "Bank 1 Sensor 1" Bank 1 is on the passenger side; Bank 2 is on the driver's side. Sensor 1 is the upstream sensor (near the frame, between the block and the cat) and Sensor 2 is near the Y-pipe (downstream of the cat).
Normally it is the upstream sensors (sensor 1) that go first. They see the harshest conditions. You will need; Oxygen Sensor Socket Anti-Seized Penetrating Oil Sometimes it will take 15 minutes or take a few hours it depends on your luck…
What does it mean when the hold light comes on in a kia sportage 1997?
The button on the side of gear shift has been depressed! This holds transmission in lower gear and should not be used under normal driving!
What to do when the vehicle produces black smoke?
Black smoke is a indication that the air/fuel mixture is overly rich. Seek professional help to solve the problem.
Are after-market oxygen sensors as good as Factory?
on some vehicles the universal aftermarkets are ok to use, however on dodge, Chrysler and jeep vehicles they don't work the cel will cme back on the dealer part in this case is actually better.
My 1992 sentra has a low rough idle and the number 4 spark plug is oil soaked?
Your valve cover gasket is likely leaking, there are o-ring gasket around the spark plug holes that will cause oil to leak into the spark plug hole.
How do you bypass an o2 sensor?
Try an EFIE. You could Google search "EFIE". Should be some on the first page that comes up. ElectoronicFuelInjectionEnhancer (EFIE). Works good with those Hydroxy boosters everyone is talking about. So I've heard at least. Hope this helps.
Where is the oxygen sensor on a 2001 Dodge Caravan?
There are two, in the exhaust behind the engine.
There are two, in the exhaust behind the engine.
How do you can a Chevy S-10 O2 sensor?
go to a electronics store and try to find a restore that you can connect to the plug. that is the best way i know how to get rid of any sensor
Where is egr flow sensor located in 2001 ford focus se zetek engine?
It is a small black box about 1 1/2" x 1 1/2" x 1/4" under the air intake hose and behind the spark plug wire coil pack. It has an electrical connection and has two air ports labeled REF and HI. Photo of the '01 replacement DPFE Sensor (thanks to Jaspo from the FocalJet forums):
Where is the O2 sensor located on a 1997 Nissan Sentra?
o2 sensors are in the exhaust
Usually in front of the catalytic converter near or in the exhaust manifold.
Where is the o2 sensor bank 2 sensor 1 location on a 2003 ford f-150?
Bank 2 is the driver side of the engine on your Ford and sensor 1 is close to the engine
in the exhaust before the exhaust enters the catalytic converter ( upstream )
Where is Location of oxygen sensors on 1997 Chrysler LHS?
On each of the exhuast manifolds right behind the convertor
How do you repair or replace sensors with fault codes p0105 p0130 p0150 p1445?
p0105 MAF sensor circuit
p0130 02 Circuit malfunction bank 1 Sensor 1
p0150 02 Circuit malfunction bank 2 sensor 1
p1445 not a generic code need vehicle info to gues
All these codes are faulty Circuit codes. So more likly a bad wire, fuse or computer than all the sensors.
Looking at the list I am going to make a guesses starting from most to least likely:
1stThere is a problem with a damaged or broken wiring harnes at the computer. Get a wiring diagram and prove the wiring is good on all the wires to all the sensors on the list
The ECM that runs all this stuff is bad.. Prove the sensors are not bad before replacing an expensive computer.
Next: All these sensors are faulty, crash or used parts or vandalized?
Is the Speed Sensor and the Speedo Head the same thing for a 95 Ford Taurus?
No. The speed sensor is located on the transmission, and is what drives the speedometer cable, which drives the speedo head. The speedo head is another name for the the speedometer, which is the display gauge that you see while sitting in the car.
Where is the oxygen sensor in a 1992 Honda Prelude and how do you change it?
Oxygen sensor or lambda sensor is situated in the exhaust pipe in front of the catalyst. Disconnect from loom and unscrew with large spanner.

You will need;
Oxygen Sensor Socket
Anti-Seized
Penetrating Oil
I have even used a small plumbers propane tank and heat it up and it help get them free.
Sometimes it will take 15 minutes or take a few hours it depends on your luck…
Which o2 sensor do you replace for DTC too lean bank 1 and 2 - Taurus - Sable?
Question: if your child has a temperature, do you replace the thermometer that told you the temperature, or work to find out WHY the kid has a fever?
A DTC (diagnostic trouble code) reporting a *lean* condition is telling you there's more AIR in the fuel mix than the computer was expecting.
In other words, air is sneaking / leaking into the engine - for example, a vacuum leak or leaking intake valve seals (which is common on Windstars).
A little more research into the 171 and 174 codes specific to the Taurus/Sables will avoid unnecessary 02 sensor replacements...
Also highly unlikely that both sides would have a failed O2 sensor at the same time, just common sense....... many things can cause a lean condition , even a weak fuel pump or plugged fuel filter , MAF sensor, injector seals and on, and on.

Buy the item and the nice person behind the register will take it off for you. Simple.
How can you tell if a catalytic converter is bad?
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 emissions are fine, then so is everything else.
