In order for a modern automobile engine to be properly managed, it must be able to detect the details of the environment that surrounds it, as well as acquire information regarding its own processes. These tasks are performed by a variety of sensors, and one of the most important sensors to an engine is the oxygen sensor. The oxygen sensor is mounted in the exhaust stream, and simply put, it measures the percentage of oxygen found in the exhaust gases which are leaving the engine. Why is this important? For the vehicle’s computer, the composition of the exhaust gases gives clues as to how well fuel is combusting inside of the motor. If the ratio of fuel to oxygen in the exhaust gases is high, then the computer knows that it needs to scale back fuel delivery. If there is more oxygen in the exhaust gas than unburned fuel, then the computer will make the opposite adjustment and add more fuel to the mix. This form of control allows an engine to be much more efficient, and also control the amount of greenhouse gases exiting the motor. How does the oxygen sensor work? A probe inside of the sensor containing platinum-coated electrodes generates a voltage in the presence of oxygen. Some models also work by changing the resistance of the electrodes, which have a current being fed through them, in response to the air / fuel mixture in the exhaust gases. The computer samples this voltage a specific number of times per minute in order to get an accurate picture of the composition of the exhaust gases.

Response From Double J

There are 2 O2 sensors...

One is in the exhaust manifold ,rear of the engine, in manifold by firewall.

The other one is in the exhaust behind the catalytic converter.

Response From Guest

well the one the guy gave me is the premium oxygen sensor made by BOSCH its like a goldish copper color and has a black,silver, and white cords i dont know if that will help u

Response From way2old

Hey Guest. Please post the exact code number that was read to make them tell you the O2 sensor is bad. A lot of times the O2 is good ans something else causes the problem. Here is a partial list of O2 codes. This does not include manufacturers codes. You can see why we need the specific code. The last 4 are not for O2's, but a lot of parts houses wilol sell the sensor to try to clear the code. Remember, the parts person is probably NOT a technician/mechanic.

Response From Guest Top Rated Answer

CHEVY IMPALA 01 3.4

Response From Double J

P1404 is an EGR code

Possibilities are faulty EGR valve, PCM, wiring/connections..


The oxygen sensor itself its the "heated oxygen sensor"....
see above diagrams......

Response From way2old

If you have an EGR code, that can cause an O2 code due to the wrong mixture of fuel and air going into the engine. If the mixture is wrong going in, it has to be wrong coming out and the O2 sensor can pick up on that. Your code is for the O2 sensor heater. That usually is the sensor itself. On the EGR code, have the EGR removed and check to see if carbon is on the pintle holding the valve from operating.

Question From bluez956 on Mercedes oxygen sensor

1991 Mercedes 300TE 3.0 120,000 mi.

I am getting a fault code saying that the oxygen sensor has a bad ground. I have checked the entire exhaust system and cannot find an oxygen sensor. Where do I find the oxygen sensor the fault code is referring to?

Response From Hammer Time Top Rated Answer

It only has one


Response From Tom Greenleaf

General info as I personally never equipped myself with special tools or info for full service on these cars. A couple local shops only worked on them if more than totally routine maintenance.
Just like you could have found on part look up where it thinks (says) it's located as said below. Some things to check are the wire(s) to it and if routing is touching anything rubbing thru or if wire into it has rusted off how clamped on. There will be a plug to check as well.
If you remove it to just look at the thing for debris, color high chance you'll break it or the manifold or pipe so watch out for that. I'm not alone but in a rust belt area and these cars are actually WORSE than average for dumb stuff so much as removing parts to check/replace an air filter can get in trouble with steel studs into alloy parts w 10mm nuts snap right off flush - a problem.
I'm not sure if a code trying tell you bad ground means too much or too little. Check grounds all over a car this old anyway even likely that exhaust system is grounded to body with a strap or two?
Can find parts on line as needed but totally suggest only real OE parts (clones are everywhere) as dealer parts can be insanely expensive but available.
Side note: an '87 300E was here, not mine to deal with in total but check out several things for what was a clean looking car junked because of a broken windshield so rusted unseen under molding was beyond possible repair vs value as parts - bummer,
T


"The Oxygen Sensor is located:
Under hood, passenger side, rear engine area, below exhaust manifold to exhaust pipe flange, mounted in exhaust pipe "
So even with this pre OBDII it can and will throw codes or a check engine icon. Doesn't mean the item it points to still but rather that circuit.

Question From Guest on Oxygen Sensor

Where is the oxygen sensor located at on a '95 Chevy K1500 4.3L V6?

Response From Hammer Time Top Rated Answer

It's in the exhaust pipe, to the right of the transmission.

Response From Guest

Alright, thanks.

Response From Guest

Do you have any suggestions for removing a seized sensor?

Could I try spraying some PB on it? I wasn't sure if that would damage the new sensor once its installed.

Response From Loren Champlain Sr

You can try whatever is at your disposal. Heat will, sometimes, work. But, gotta be real careful using it. Once you do get the sensor out, you can clean the threads in the exhaust pipe with a spark plug tap. (14mm, I think) Should be able to get one at most any parts store. Be sure to use anti-sieze on the threads of the new sensor before installing it.

Response From Guest

Yeah, it took heat, a lot of heat! ha. I just re-taped it out and got the new one in with some anti-seize and all is well, thanks.

I don't think I've ever seen anything as seized or corroded as that sensor was.

Thanks again.

Response From Loren Champlain Sr

Glad to hear you got it. Was just re-thinking my reply...18mm tap? The memory is definitely the second thing to go. sigh. It really is very common for those things to be siezed. Good job, and thanks for letting us know how it went.
