As similar as all the OBD2 oxygen sensors are, are they all the same ?

My primary is shot from seeing too much fuel. As soon as I installed the JRSC, the tune was probably too rich for my setup.

It is either going to be buying a new stock sensor, buying a wideband, or try and use the secondary.

Has anyone used the secondary o2 in the manifold before?

 

Same thing

 

Damn 04 members.

What else have you found under the car?

 

well well well

what a pleasant surprise

The thing that was throwing me off is the price of a primary and secondary. I can get the factory primary for about $90, but for a secondary it is going to run me about $140.

 

Looking at Baranco's site....They are 2 different P/N's and the same price Kevin.

Hell try switching the 2 and see what happens.

yea ive done it b4 swaping them it works

dude, I told you I buy my O2 sensors elsewhere. $90 as compared to $202, for the same exact part.

Anyhow, I will swap them out tomorrow guys. Thanks for the info.

 

swapping them works.

same sensor - the 2ndary just has a different p/n due to the fact that it has a rubber grommet that prevents dirt and water from coming up in that hole under the car.

Huh? Really? the rear one should have a heater?

yes.

see my post above.

both have four wires - one white, one green, and two black.

heater, signal, and two grounds.

Good deal. Easy fix for me

If primary sensors fail due to too much fuel (sometimes.... - and remember this happened as soon as I supercharged the car) is the secondary less likely to fail due to its position in the cat?

Last coupla O2 sensors I've used were for a GM car, the primary o2 was a one-wire. Thanks for the edumacation. I'm still running my OEM one.

If anyone would have that happen, it'd probably be me.. My wife's melted hers from running lean once or twice..

I woulda guessed, the primary runs so much hotter, it'd be more immune to running rich.

 

I swapped my secondary in place of the primary about 2 years ago, still works perfectly.

 

well I find it very strange that a sensor that was installed back in September and has seen only 2k miles would die the very day that I install the supercharger.

Is it possible for a function of the ecu to be bad causing this ?

In the mean time, I am going to swap the O2's right now - or as soon as the exhuast cools down enough.

You can get a primary o2 sensor code for lots of reasons. Many of them are just tuning issues.

isn't it also likely that you may have unplugged or pulled on the primary o2 sensor wires during your installation? I'd check there first... then reset the ecu and see if the code comes back.

I think your car is just allergic to boost.

Duh chris... (sorry i didn't make it to autobaaahn on sat, heard you did well!)

1102 (huhu, i was '1107' on here for a few months) -
Check your wiring first off. The wires going into that plug (both top and bottom) easily come out and its easy as hell to mix up the two same-color wires if you did happen to pull them out of the plug (i can't remember if there are two greens or two blacks, but you get the point - blah, kenEE says blacks).

If it isn't that, then its your o2 freaking out for a/f ratio reasons.

chris - who wonders if $90 is the cheapest price on o2 sensors... the type pos primary has been giving intermittent failure codes for... a year goes away when i disconnect negative on battery. (still getting good mileage, though, so must be working cept when the code kicks in)

 

Guys, I am almost 100% positive that the the O2 isn't unplugged. Ever since we installed the supercharger he has been getting a code. He has reset the ecu several times and it comes back.

yes, and it is completely random. I drove 5 hours highway and did not see the code, but a different day, 5 minutes of driving in town and it popped on.

It is a soft code - it disappears every time I turn off the car and does not stay.

I swapped them out today. All of the wires are connected and secured.
As for the tune being a possibility, I highly doubt it.
It was doing this on the tune that I ran before I went to get tuned (sounds funny, but I purchased the JRSC / Hondata from Jim). Now it is doing the same thing which is after I had the car tuned.

 

Since this is a soft code and goes away every time I restart the car, do I need to reset the ecu after swapping sensors?

 

1102- this, to me, is the sign of an o2 sensor that is 'going bad'.

My primary o2 is doing this right now and has been for a while. The code I get every time is 'primary o2 sensor/heater failure' or something like that. When the CEL goes on, my car dumps fuel as if it is in limp mode, but without the 3k rev limit. when its reset, it is back to normal. I suspect the o2 sensor is not working properly - either it is going bad, or it needs to be cleaned off b/c its covered with soot from a stock/rich air-fuel mix. That add the car has 95k on it and is 5 years old.

I cleaned it out with carb cleaner and the code came back. I was told that carb cleaner could possible foul the sensor or that it could clean it... so I figured I had nothing to lose since it was already acting up.

Anyhow, we will see what happens with the other sensor in there now.

What did you guys use to plug up the hole above the cat (where the rubber grommet used to be on the secondary wire) ?

I just used a rubber grommet from home depot.

It's not necessary, as that hole really won't get much up in it anyway due to its location.....

You can always cut off the grommett from the o2 sensor and stuff it back up in the hole.....
