Yeah for some reason they like to charge you out their *** for 02 sensors.
My Si has a malfunctional 02 sensor, i called the auto zone, and they said they want 100 just for a sensor which checks the health of the cat. Screw that, i drive my car with the check engine light, now i'm begining to like my check engine light.

Just take the CEL bulb out of the guage cluster.

Re: $300 for O2 sensory??? WHAAAA??? (blykins)
Obviously if you have absolutely no problems with the car except for the CEL, screw it; im gonna go and spend 300$ on the sensor cause my car just runs like ****; Oh yeah, this friday i went to the junkyard and bought an o2 sensor for 30$, but it was fucked as well, so there is a downside to the junk yards

Re: $300 for O2 sensory??? WHAAAA??? (h22civic95coupe)
if your second o2 sensor (i could be wrong, but im 95% sure im not) is gone, it isnt much a problem, the check engine light will come on but thats it. if you have obd1 then your in trouble though. check engine lights arent good for ****, theyre only related to emissions, and most people dont give a **** about that.

I thought they start running lean, if something goes wrong and you trip the Check Engine light?

CEL will make your ECU go into "limp mode". Part of imp mode may be running leaner than normal. It basically just makes your ECU not perform 100%.

i drive with my check light on for most of the time. everytime i reset ecu try to get rid of it, it comes back within a day. i m still boosting 8psi daily with greddy kit in my 2000 civic ex. it's been a year now. **** it..

No it doesn't...
MAJOR ecu codes make the ecu go into "limp HOME mode".... NOT the o2...
and to whoever said obd1 it's BAD... NO it's not... I have NO o2 sensor in mine and it runs FINE... NO problems other than an annoying yellow light on the dash...
Autozone DOES sell bosch universal o2 sensors for around 70 bucks...
the REASON our some honda o2's are CRAZY expesnsive is because they used a WAY more advanced o2 than most do... it's a 4wire o2 which is heated in order to give quicker readings... AND to give an ACTUAL lamda number intead of a simple Lean/Rich signal...

Seems like neither of you have any idea what you're talking about. An O2 sensor code (obd1) will most definitely make your car go into limp mode. Limp mode causes your ecu to not use your O2 for fuel trim settings. Instead it runs off the default maps which make your car run waaaayyyy rich. Honda does this as a safeguard because while more fuel isn't fuel efficient and can cause carbon buildup it will not blow up your motor. And the car will seem to run good because it's dumping a shitload of fuel but you will obviously notice a big increase in fuel consumption. If you still have a cat on the car and are running off the default maps you will burn the cat out in a matter of a week or 2 because of all the unburnt fuel.
In obd2 if you have a primary O2 sensor code you will run in limp mode, if it's the Secondary O2 sensor code it will NOT run in limp mode because that sensor is only there to check the efficiency of the cat. It compares the readings with the primary O2 sensor.
Now in both obd1 and obd2 there are codes for the O2 sensor heaters, not sure if that causes limp mode. I would guess not but can't be sure.
As for the O2 sensors honda uses they are not that advanced. 4 wire O2 sensors have been around for quite a while, honda has been using basically the same one since 1992. They are narrowband and can only operate close to stoic (14.7:1 a/f ratio) and all they basically do is tell the ECU to go lean/rich. It doesn't have much of an a/f detection range, hence the name narrowband. You can really see it in the corresponding voltage readings they put out. Now the newer honda cars (the RSX and the new Si) use wideband O2 sensors so they can detect an a/f ratio from probably around 10:1 to about 16:1 to get them really fuel efficient while still being able to produce a lot of power. It might be a larger range than that even. I'm not sure. Most new cars seem to be using widebands. The bosch UEGO sensor that the AEM wideband unit uses is an audi/VW OEM unit that they use in there 1.8T engines.
Hope that clears some stuff up.

Re: $300 for O2 sensory??? WHAAAA??? (stevel)
oh, and to answer the question for this post just get a universal one and splice on the sensor from you stock one. Or get it from oxygensensors.com with the plug already on it. It's your choice. The dealer charges you a lot because they suck. 4 wire O2 sensors are all the same. The plug might be different but just make sure to get a bosch.

THERE are SEVERAL diy wideband o2 kits that use the HONDA heated o2... So actually it's pretty friggen advanced... Sure they've been around for a while that doesn't make it NOT superior to a standard o2.

Re: $300 for O2 sensory??? WHAAAA??? (sombasol)
The reason I brought this up in the first place was that I was just thinking about replacing it when I install my new header but that kind of money is just stupid. this is the first time I've had to agree with a domestic owner saying that parts for there car are so much cheaper.

Well, we're using the 4 wire O2 sensor that's narrowband and it's a standard sensor that tons of other car makers use. It's not specific to honda. I wouldn't call a 10+ year old design advanced. Now the 5 wire wideband that was used in the VX is again at least 10 years old and just has a wider voltage range. It's primarily used because it was a high volume piece so could be had for relatively cheap.
Hope that clears some stuff up.

actually if you look around you can get a universal for about $50. It might be worth replacing when you take the header off because with some headers there's no way to get the O2 sensor off without taking the header off which can be a real pain in the ***. The other thing is that O2 sensors usually don't just go but degrade over time and how fast they detect gets slower over time so you'll gradually get decreased efficiency. Wouldn't hurt to replace when it's easy.

You know that little yellow annoying light on your dash? Yeah, it's telling you you're running in default mode.
Limp mode indicates that you CAN NOT enter vtec... it will not let you rev over a certain range and it runs REDICULOUSLY rich... NOT off the stock fuel maps... HEAVILY rich. Which mine is NOT doing... obd1 and all. And no that little light on the dash is telling me there's a problem with the o2 sensor and to get it to a dealer.
Yes "default mode" would be more "appropriate"... just as incorrect... but sure... it's running the default fuel maps which it does in wot ANYWAY. it's called OPEN LOOP... which just means it's ignoring the o2 sensor and runninf off the fuel maps... like I said before your car goes into open loop at wot ANYWAY.. yes it runs a LITTLE rich but not as rich as it would if it were in "limp home" mode.
Well, we're using the 4 wire O2 sensor that's narrowband and it's a standard sensor that tons of other car makers use. It's not specific to honda. I wouldn't call a 10+ year old design advanced.

As I said.... I'm SOOOO sorry I used the word "advanced" and confused you... it IS in fact superior to the NORMAL o2 sensor used in MOST cars... which only sends a simple Rich or Lean signal to the ecu...
Hope that clears some stuff up.

Now the 5 wire wideband that was used in the VX is again at least 10 years old and just has a wider voltage range. It's primarily used because it was a high volume piece so could be had for relatively cheap.
As I said.... I'm SOOOO sorry I used the word "advanced" and confused you... it IS in fact superior to the NORMAL o2 sensor used in MOST cars... which only sends a simple Rich or Lean signal to the ecu...
Hope that clears some stuff up.
