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 an 1987 S-10 Blazer 2.8L?
It sits under the SUV where the two exhaust pipes connect into one. There are probably three, one where the two ehaust pipes connect into one and one before the cat. and one after the cat.
How many oxygen sensors does a 99 Mazda millenia have and where are they located?
I have a 99 millenia myself and it has 4 (four) 02 sensors, and each go for around 200-450 in price. I don't really know where they are located though, but i do know they can cause your check engine light to come on and flash from time to time, as well as the car hesitating and feeling like it is going to stall.
Each O2 sensor has four wires going into it. Two of those wires are ground and power to a heating element inside of the O2 sensor, and two of those wires are for the Powertrain Control Module (PCM), or the "computer" to get O2 readings from the sensors.
The codes you have indicated are because the PCM sees an incorrect draw on the heating element circuits on both the upstream and downstream O2 sensors on bank #1 (possibly an open circuit), and it sees a faulty signal on the sensor circuit on the upstream O2 on bank #1. It is a small chance that you have two bad O2 sensors on bank #1, but more likely you have a wiring problem. There is no fix that anyone can tell you without being able to run circuit tests on the car. Now, if you want to try and blow a couple of O2 sensors on the car yourself, they are about hundred bucks each. If that seems better to you than spending $80 or $90 to go to a shop and let them diagnose it, then that's your choice. But that car needs to have the wiring harnesses ohmed out in the suspect O2 sensor circuits to make sure you don't have a wiring problem first. The PCM itself could even be your problem. There is no way to know without checking the car out in a shop.

How do you remove an oxygen sensor that is stuck?
If you have the room I would cut the wires off at the sensor and slip a 1/2" drive, 6 point, 7/8" deep socket with a long breaker bar over the sensor.

Is there an oxygen sensor fuse on a Jeep Cherokee?
Yes there are two, one for the front and one for the rear. They are located to the left of the battery if your facing the engine inside the fusebox. Just remove the cover.
Where is oxygen sensor bank 1 sensor 2 for mercuery mountaineer 2003?
Bank 1 is the passenger side of the engine in a Mercury Mountaineer ( V6 + V8 )
Sensor 2 is after the catalytic converter ( downstream )
Where is bank 1 on a 1998 Ford Expedition 5.4L?
Bank 1 is the passenger side of the engine in a Ford Expedition
Where is bank 2 sensor 2 oxygen sensor located in 2004 Toyota highlander?
The rear cylinders are 1-3-5 so that is bank 1. Front cylinders are 2-4-6 so that is bank 2. Follow the exhaust pipe from bank 2 and you will find the O2 sensor.
Where is the antiknock sensor located on a 1999 subaru foister?
The knock sensor is mounted on the left side of the engine behind the manifold towards the back of the engine in a small recess. It is circular and aprox 1 inch in diameter. It is fastened to the engine block that goes right through the middle of the sensor. If you replace it then be carefull to use the right torque when fastening or it might function incorrectly or break. Also the sensor must be posisioned so that the cable comming out does not hit the walls of the recess when you toghten the bolt so make a not of the orientation before you remove it.
Sensor 1 bank 1 oxygen sensor 2001 Chevy 2500 hd 8.1L?
Oxygen Sensor
Some vehicles have (2) and some have (4) O2 sensors.
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
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...
Where is the oxygen sensor on a 1995 Hyundai Accent?
located on the exhaust manifold just before the flex pipe.
How do you replace an oxygen sensor on a 2000 cavalier?
Caution:On models equipped with Delco-Loc 2 or Theftlock audio systems make sure you have activation code or lockout feature is turned off * Disconnect the negative battery cable * For access to the downstream oxygen sensor raise the vehicle and place it on jackstands * Follow the harness from the sensor to the electrical connector then unplug the electrical connector from the vehicle harness * Carefully unscrew the sensor from the exhaust manifold
Where is the oxygen sensor located on a 2001 Dodge Ram 1500 5.9?
The oxygen sensor is mounted in the exhaust down-pipe
What is upstream and downstream o2 sensors?
upstream 02 sensor located right above exhaust manifold gasket downstream located right in front of catallytic converter
Locate Ford Expedition XLT O2 sensor?
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.

Where is the o2 sensor located on 2001 Chevy venture?
Depending on which engine you have, there are several O2 sensors and they are all located on the exhaust system at different points.
How do you replace an oxygen sensor on a 2003 Chevrolet Impala?
It would be cheaper to let a repair shop do it as the special socket to do the repair cost around $75.00. If you do not use it very often then the cost out-weights the benefit.
--------------
It requires a special 22 mm or 7/8 inch socket with one side cut out . I found it at most major auto part stores for about 5 to 20 dollars.
Often your car will let you know ahead of time when something is screwy by turning on the Check or Service Engine Light.
Some Auto part store will read your Check or Service Engine Light codes for FREE. All you have to do is ask!
YouTube or some others web sites have video to show the location and how to change the O2 sensors.
Where is bank 1 sensor 2 on a 1998 ford explorer?
passenger side, the sensor closest to the engine
This is incorrect. Bank 2 is on the -drivers- side of this vehicle. On this 4 liter SOHC motor Bank 1 is on the same side where the #1 cylinder is located,which is on the -passenger- side. I found this out the hard way . After reading this posting, I replaced the O2 sensor on the passenger side of my 98 Explorer. It didn't change anything. After reading a posting elsewhere and many hours of diagnostics, I switched the O2 sensor to the drivers side,and reset the computer. Check engine light has been off ever since.

My same problem:
I have exactly the same problems with my Lexus but this is a early 97 one. the bad idling is not noticed by the EQ I think as there is no engine light burning. I have read on a forum that someone changed the engine mounts and drive shaft trannys to get rid of the vibrations at higher speeds. Is your one vibrating when pulling or braking on the engine at high speeds? In my case it is only vibrating when I am cruising at a constant speed. I checked mine but could nog see anything particularry there. Still I ll try to change them as they cost only $24 on eBay. Try the O2 sensor tutorial on www.lexls.com . And please let me know when you solved the problem as I have the same problems.
Good luck searching!
