Question From eyob07 on o2 sensor

Hi there everyone I,m just curious what is the difference between o2 sensor and air fuel ratio sensor.

Response From nickwarner

Some manufacturers call it one thing and some call it another. What matters is if it needs to be replaced. Here's an easy way to tell.

If a professional driveability technician tells you it needs bo be replaced, it does and you should buy a factory sensor if you want the car to run right.

If some kid popping zits behind the counter of Advance Auto Parts just did a free code scan and wants to sell you a bunch of Bosch sensors by saying the code means that is what you need, you don't.

Response From Discretesignals

Both air/fuel ratio (wide band) and regular O2 sensor (narrow band) are both called O2 sensors. A narrow band O2 sensor produces its own voltage and a wide band is powered by current from the engine computer.

There is plenty of information on the internet about the different types of O2 sensors and their theory of operation.

Question From Wags391 on 1992 S10 Blazer O2 sensor

Where exactly is the O2 sensor on a 1992 Chevy S10 Blazer, 4.3L, 4X4?

Response From Tom Greenleaf

Follow your exhaust system. They look like spark plugs and you probably have two! Bonne Chance,

Response From Tom Greenleaf

Just follow the exhaust system starting at the engine. You probably have more than one,

Response From Wags391 Top Rated Answer

I found that on this particular model, the O2 sensor is located right before the cat. convertor.

Question From dragtime92 on o2 sensor 94 blazer help

ok the o2 sensor seems to be stuck WILL NOT COME OUT stripped the bolt around it what should i do ???

Response From Loren Champlain Sr

We run into these every so often. Had two last week. aarrrgghhh. It is a 7/8" hex. Buy an O2 socket. They are six point, instead of 12 point. You'll have less of a chance of rounding the head...You do not want to do that. Only, if you feel comfortable doing it, and have a fire extinguisher and/or garden hose ready,Apply heat, very carefully so as not to catch anything on fire, then quickly get the socket and ratchet in there and hopefully, you can get it to come out. If the threads are damaged in the exhaust, which they probably will be, buy a 14mm tap and retap the threads, again being very careful to get the tap started straight. Be sure to use anti-sieze on the threads of the new O2 sensor so the next guy will be able to remove it.

Response From dragtime92

ok one question would you be able to drive without an o2 sensor in the exhaust what would happen in the long run...

Response From Loren Champlain Sr

Nope, can't run without one. The O2 sensor directly controls fuel delivery. Severe engine damage is possible, Catalytic convertor damage likely. Sorry.

Response From dragtime92

ok how bout this drilling a new hole into the pipe and disconnecting the old one and cutting it off so it doesnt look noticeable would that be ok

Response From Loren Champlain Sr

Tom brought up a very good point. A light bulb lit up in my head. (okay, it's a dim bulb) You could take the assembly off and take it to a muffler shop. They surely could extract the old sensor for you. As far as the threads, if they are damage beyond repair, the muffler shop could probably braze the new sensor in for you. But, next time, the assembly will have to be replaced. As far as drilling a new hole and installing the sensor there, won't work. The pipe is too thin. As Tom mentioned, there is a threaded nut welded on the inside of the pipe for the sensor to screw into.

Response From Tom Greenleaf Top Rated Answer

These are a pest as Loren noted. At some point replacing the pipe (pretty big bucks) could be the best option.

If you could remove the whole pipe which should look something like this....

/

You might be able to weld in a new threaded nut or if there's room (doesn't look like it) make a new threaded hole to receive the sensor and properly plug off where original was with perhaps an oversize self tapping drain plug if you can find the right size.

They look something like this....

Question From Guest on o2 sensor question

Is it possible for a bad o2 sensor to cause a misfire in one of the cylinders?


jat

Response From Tom Greenleaf

Possibly. Depending on where sensor is and how car's computer deals with info from it - it could mis adjust the amount of fuel needed and perhaps just one cylinder can't deal with the now improper mix.

What is this car? Taking plugs out for inspection can tell a lot about what that cylinder is doing or doing wrong,

Response From Guest Top Rated Answer

2003 chevy 3500 express van
I got a code for bad o2 sensor and misfire in cylinder 3. Changed the sensor, and the check engine light is now off but I only ran truck for 10 minutes. Will find out tommorrow if the truck is ok, when it will be used all day. I also got codes for truck running lean which I thought was related to the bad o2 sensor.


thanks for any help

Question From gthomas on O2 Sensors

I have a 96 Saturn SL2 and the "service engine soon" light is on. It was diagnosed as the secondary O2 sensor sticks sometimes. Is there anything I can add to the gas tank that will fix this? I don't have the money to get it fixed.

Response From Hammer Time Top Rated Answer

O/2 sensors don't "stick"
What was the exact code number?

Response From gthomas

I don't know, I was told the code meant it was the secondary O2 sensor by a guy at Auto Zone. Another guy said that it worked intermitently

Response From Sidom

No offense to the parts guys but they aren't training to diagnos. They are just pulling codes and codes just tell what system is being affected & not the problem. Granted OBD II has a lot more "specific" codes now but some are still just common system faults...... There are some pretty specific 02 codes that usually indicate a faulty 02 but there are also lean bank codes that come up that I've seen people blame on O2s where that is almost never the problem.....

They didn't give you a print out or wite it down for you?

Response From gthomas

Sidom, I just got the codes and they are:

P0141
P0563
P0562
P1555
P0565
P0560
P0605

Response From Hammer Time

OK, only one of those codes has anything at all to do with an O/2 sensor. The downstream O/2 has a heater problem. You will have to test for power and ground arriving before replacing it.

PO555 doesn't exist for that vehicle


PO560,PO562,PO563 all have to do with system voltage fluctuating. You need to monitor the charging voltage to see if it is jumping around for some reason

PO565- Cruise control indicator problem

PO605 EPROM error. That is an internal computer problem. It could have something to do with the voltage fluctuations

Response From gthomas

I cut and pasted your comments with a comment of my own( in RED) beside it:
OK, only one of those codes has anything at all to do with an O/2 sensor. The downstream O/2 has a heater problem. You will have to test for power and ground arriving before replacing it.

PO555 doesn't exist for that vehicle - I meant to say P1555


PO560,PO562,PO563 all have to do with system voltage fluctuating. You need to monitor the charging voltage to see if it is jumping around for some reason- How do I do this? Will the voltage regulator need to be replaced?

PO565- Cruise control indicator problem -I know, it doesn't work- How do I fix this?

PO605 EPROM error. That is an internal computer problem. It could have something to do with the voltage fluctuations -How is this fixed?

Response From Hammer Time

You have extensive multiple problems here that will require considerable time to diagnose them individually.

Response From gthomas

I thought so. I guess I will spend the $50 and have the mechanic down the street diagnose it and see whether it is worth putting the money into. Again, I thank you so much for your Professional opinion and the time you have invested in this (and me). Are you in Michigan and would you be interested in what the final verdict is?
G. Thomas Martin
If so, I can be reached directly at gtmartin2002@yahoo.com

Response From Hammer Time

We always like it when people post back the solution here on the forum so all can see it.

Response From gthomas

Yes, I will post back once all is said and done. Is there any chance in Hell that this be be a relatively inexpensive, one size fits all (voltage regulator?) fix?

Response From Hammer Time

I'll repeat the same thing. the guys at AutoZone are nothing but sales clerks that think they are experts and know nothing. The whole reason they do this for free is to sell parts so in order to do that, they have to make you think they know what they are talking about but in reality, my cat knows more than them.

Get the code number and we can tell you what it means.

Response From gthomas

There were 6 codes that came up including low voltage and high voltage. He wants to charge $50 to do an electrical diagnosis

Response From Hammer Time

I just want the code numbers, not a diagnosis. They do that for free.
If you have been unplugging anything, you may have set some of those codes yourself. You may have to record and clear them and then see which ones set again.

Response From gthomas

Hammer Time, here are the codes I just got :

P0141
P0563
P0562
P1555
P0565
P0560
P0605

Response From gthomas

Okay, I'll run up there again and get the codes only and No, I have not unplugged anything

Response From Hammer Time

Tell them to clear them after you write them all down. They will all start with a "P".
We may have to go read them again later.

Response From gthomas

No they didn't and the other thing is my exhaust is rotted out and I won't just replace the sensor with this exhaust, I need to repalce the exhaust from the manifold, back once I get back to work. Thank you for the information. May I ask you another thing to? Does this faulty O2 sensor cause the car to idle very smoothly but when I drive it, it periodically has a very hard miss and thump coming from the rear end (in a front wheel drive vehicle)?

Response From Hammer Time

We can't really tell you how it will effect the engine until we know what the code is. There are about 20 different codes referring to the O/2 sensor all meaning different things.

If you have an exhaust leak ahead of the sensor, that can be your whole problem with the sensor code.

If you have a noise coming from the rear of a front wheel drive car, it's certainly not the engine or transmission doing it.

Response From gthomas

I'll take it in to get a code today. Just so you know, when I had the problem originally, last year, I added a bottle of Lucas Fuel Treatment to the gas tank and in a few days, the problem (bogging, missing and hesitating) went away. I did that after I had the code cleared and the light went off. If this helps

Response From gthomas

I don't know. The guy at auto zone said his computer told him it was the O2 sensor. Another guy siad that he thought it would work, then stop, than start again

Response From Sidom

If your rear O2 is staying centered, then it will need to be replaced. There isn't any quick fix for that. The good news is on that old of a vehicle, it doesn't use a rear fuel trim stategy and the rear O2 is just a cat monitor, so you will just have to put up with the SES light & not worry about a drivability problem.........
