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.
Which one? Upstream or downstream?
In my opinon, your coil pack is probably not the problem. If your car runs then the coil is functioning, that is the spark plugs are firing. If the spark is not hot enough to burn all the fuel, I'd try new plug wires or hotter plugs. Could be an injector problem. check the resistance accros the...
wich one it has two one on the manifold and the other one on the exhaust pipe
As far as I know , the ( 2 ) oxygen sensors on a 1995 Ford Explorer are right in the outlets of the exhaust manifolds on both sides of the engine so they are both before the catalytic converter Bank 1 is the passenger side of the engine Bank 2 is the drivers side of the engine In a Ford...
Bank 1 is the drivers side head. The sensor you want will be screewed into the drivers side exhaust pipe and will be the 2ed one back towards the muffler in the drivers side exhaust pipe.
Answer . \nIMPORTANT: DO NOT DROP THE OXYGEN SENSOR. EXTREMELY FRAGILE!!!!\n. \nFirst figure out which one to replace. Buy a sensor for your model car or a univeral one. Should require four wires. Use a slotted socket or a wrench to remove the old sensor. Cut the wires approximately 3 inches...
Answer . There is no fuse. It means there is a problem in the catalyst moniter heater circuit bank #2, sensor #2. here is a brief description of why this code was set:\n. \nDuring testing the HO2S Heaters are checked for opens/shorts and excessive current draw. The test fails when current draw...
In a service manual at a dealer, parts store, or library.
With out knowing what code is stored in the computer, that cannot be answered.
There is NO right are left bank knock sensor. If you are smart you will replace BOTH of them while you have the intake off. You do have left and right bank oxygen senors, But not knock sensors.
Answer . their is a special socket made for o2 sensor removal and installation. their is a slit down one side so that the wire can come out. purchase that socket, raise vehicle safely, climb under, spray with penetrating catalyst, may need to heat up a little bit, unscrew old one, replace with...
It is built into the mass air flow sensor. That is right beside the air filter box in the air intake hose.
Answer . Simple, Remove air breather assembly then looking from the front of your tuck, behind the left side of the TBI you will see you EGR. Remove the EGR bolts(2), gasket, and line. Replace it with an OEM spec EGR and gasket, connect line and your done.
if you mean the lambda sensor it could either be located just after the turbo or it will be on the up pipe to the turbo its all according which model you have but just unplug it and unscrew it and replace it and then plug it back in.
in the exhaust pipes behind & in front of converters
May possibly be: Bad or clogged fuel injector, or needs tune-up. (Bad spark plug, ignition wires, cap and rotor), May need a new gas cap, may need new airfilter and PCV-valve. May need fuel system flush. May need fuel filter.
Answer . \nusually, at the age of your car, the oxygen senser goes bad and requires replacement when the check engine light comes on.. Answer . \nIt means the computer has detected a problem and a code has been set. Have the computer scanned and that will determine what needs to be done. Don't...
According to my Haynes repair manual : ( 3 ) for the V6 engine and ( 4 ) for the V8 engine
Advanced timing can cause that to happen
Maybe this will help . \nI wasn't aware that there was a middle oxygen sensor. I have a 1997 Villager that was vandalized and the catalytic converter and O2 sensors were stolen. From what my mechanic tells me and Auto Zone there are only 2 sensors, one in front of the catalytic converter and one...
Answer . can also be done with a open or boxed end wrench, but is harder to do but cheaper than buying a o2 sensor socket.. Answer . there are 2 o2 sensors on these ( i have one to) you need a special tool looks like a spark plug sockett with a space cut out on one side to accomadate the wires...
Bank 2 is the drivers side of the engine in a Ford Explorer Sensor 1 would be somewhere in the exhaust before the catalytic converter ( upstream )
there are 2 , the front one and the catalyst one.. Yes, there are two. Depending on which model you have depends on how many catalytic converters you have. On the California emissions model, the is an oxygen sensor directly above the first converter, which is immediately in front of the engine...
It is screewed into the exhaust pipe/pipes close to where the exhaust bolts to the engine.
Answer . \ni'm answering my own question. my haynes book said 3 which confused me. there are only 2. 1 is right past the cat. and the other is behind the intake manifold and is a pain to reach.
Yes, it is illegal to operate any vehicle that came equipped with a catalytic converter from the factory with it removed.
1996 and later gasoline engines are equipped with pre and post catalyst O2 sensors. The sensors are located in the exhaust mainfold one before the catalytic converter and one after.
NO...the '76 Duster's 360-cubic-inch engine (option code E58) was equipped with dual exhausts, an Air Injection Reactor (AIR) pump, and no catalytic converters. It was a "49 state" option, meaning that it was not offered for sale in California. Also, the 318 cubic inch V8 was available in all...
Answer . \nOn some models, like my 1997, there are computer updates that the dealer must do. I'm told (by the local dealer) that these updates often correct some problems and make the vehicle operate more efficiently. If you're lucky, this could solve the problem. If not?
Look under the hood, the front of the engine, on the exhaust manifold. It should be the only thing with wire/s on the manifold. You will need a special socket to remove it. The tool is available to "Borrow" from the folks at AutoZone. If you need any further info, just gimme a shout. Actually it...
Code P0136 is the code set for your O2 Sensor that is located after your Catalytic Converter.
on you exg. there is 2 02 sensors. upstream and downstream up is before the cat, downstrem is after. most 02 sensors are a bolt desing and hold themselfs in, so under the truck find the bolt with a black wire looking thing after the cat bolted into the exg., disconect it from the plug an play point ...
2, both are in the exhaust system .I am told the rear one usually is the one that need to be replaced . local Toyota dealer tells me they hardly ever replace the front one.
Answer . \nThere are four oxygen sensors on the 1997 Chrysler LHS. 2 before the catalytic converter and 2 after.
Locate the O2 sensor, it is the spark plug shaped thing near thetop of the Exhaust manifold. Unplug the old wire from the harness,find the correct size wrench (probably a 13/16") Remove the oldone. Find some O2 sensor approved RTV sealant or thread locker,apply it to the new threads. Screw in the...
Answer . I know one of them is under the front of the car right in the center. Just go over to the front your car get on the ground and look up it is right there. I here there is another one hidden in back, but I haven't seen it yet. Hope I could help alittle.
The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on,...
That would be located under the car just in front of the second catalytic converter.
Two,one in front of the catalytic converter & one behind it.
Yes. The oxygen sensor measure oxygen level in the exhaust. A knock sensor measure vibration in the engine to detect spark knock. However, modern engines use sensors dedicated to sensing oxides of nitrogen in the exhaust gas. These are often referred to as "Nox sensors". This is probably where the...
\n. \n. On a 1998 Ford F-150 or Ford Expedition , 5.4 \n. \n. Bank 2 is the drivers side of the engine \n. \n. Sensor 1 would be close to the engine BEFORE the exhaust enters the catalytic converter
On the V6 it would be the cylinder head or bank at the front of the engine. ========================================================= Actually , that would be bank #2 , the cylinder head or bank at the rear by the firewall is bank 1
BAnk one sensor one is above the cat on the back exhaust manifold. Sensor two is below the cat.
There is one located in the exhaust, just in front of the catalytic converter.
look right before the converter unless your pipes has been changed
No, it will cause a check engine light along with fuel economy and power issues.
There are two screwed into the exhaust on the rear of the engine .
There are four sensors, under car. 740i/iL has dual exhaust, 2 sensors per side, one in front of each catalytic converter and one behind. Sensors rarely go bad. Catalytic converters are sensitive to today's pourly refined gasoline and can burn out prematurely.
depends on the year some have 2 of them one behind the catalytic converter and one on the driver side exhaust just above the where the y pipe connects
They are under the car, just after the engine exhaust manifold.
Take it to repair. . Codes can be checked by anyone with a scanner, some places do that for free.
Bank 2 is the drivers side of the engine on your 1999 Mercury Marquis Sensor 1 is before the catalytic converter ( upstream ) Sensor 2 is after the catalytic converter ( downstream )
If your plan is to install a new O2 sensor, I would unplug the electrical connection to the sensor and then cut the wires off at the sensor. Doing this will allow you to slip a 7/8" box wrench over the sensor and turn it counterclockwise to remove it.
There may be more than one 02 sensor and they are all threaded into the exhaust sytem at various points, depending on make, model, engine size and year.
Hey Rodney==I don't know of any reason why not. Take it to your local body shop and have them look at it. GoodluckJoe
There are (4) two per bank one before the catalytic converter and one down stream.
Answer . possible but not likely, pull the breather and watch the injector spray patterns. They should look the same in a nice fan, if one is pouring in fuel u need to replace the bad injector. NEW ANSWER: Check the map sensor, start engine and remove vaccume hose it should have vaccume on the...
Answer . \nNo such thing as a O2 Sensor Box. The O2 sensor is located somewhere on the exhaust system. Looks similar to a spark plug with a wire connected. May be more than one.. Answer . The o2 sensor on my 1990 Mitsubishi Mirage 1.5L (same engine as the colt i believe) is on the exhaust...
No. They had no idea nor the science to figure it out.
1. Remove the 4 bolts securing the heat shield to the exhaust manifold, and lift away the heat shield for access to the sensor. 2. Trace the wiring from the sensor body back to its wiring plug and disconnect it. On models with two sensor, the second sensor is located in the exhaust pipe, under...
well first you pop the hood of your car,then comes the easy part you start counting them with your wiener
An O2 sensor can be purchased at any auto parts store.
Somewhere exhaust system most likely manifold.
Answer . There are 2 different oxygen sensors for this car. I just replaced the back one which is in the exhaust system. If you go underneath the car and look near the catalytic converter. You should see the sensor threaded into the exhaust system. It will have a chord coming from it and heading...
Answer . \nYou are incorrect. It does indeed have an O2 sensor. Purchase a repair manual at most parts stores, ( around $12 ) for detailed instructions on this and many other repairs.. Answer . \nVolvo calls it a Lambda Sond system, and the sensor screws into the exhaust pipe just after they...
Bank 1 means where number 1 cylinder is. sensor 1 is the O2 sensor before the cat. converter, not after the cat.
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 useful for...
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.
\n. \n Answer \n. \nIn 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 bulb fit but...
I just got these fixed. There is a forward (primary) sensor and a back (secondary) sensor in front and back of the catalayic converter within the muffler.
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 cigar chaped...
