SES LIGHT WON't EFFING GO AWAY!
Got headers, I just got my o2 sim working correctly (had a blown o2 sensor fuse) And reset my ecu. Plugged it up to a obd2 and it read nothing, all o2 sensors were being read as funtioning. It wasn't an autozone obd2 but one that plugs up to your laptop and reads every spec. DRove 20 miles and orange light pops back up. Wth.
Headers + o2 sim... Why isn't this thing going + staying away?
Anyone?

Did you use cruise control? When I need my SES to stay off, I just reset the ECU and remember not to use cruise control... for some reason, using it causes the O2 sensor codes to pop up immediately.

Yes I did, and now that you mention it I think that's why! Dude you're awesome. haha, Appreciate it. And The codes would always pop back up at both secondary sensors. As soon as I used cruse control it seemed to just pop it right on, I'll double check tomorrow. I've been using cruise tons more the past 2 weeks for some random reason.

me neither, does this mean you guys with this problem cant use your cruise control anymore or you'll get a ses light? Or is this not an issue once the ecu has relearned everything?

I have the same problem. I am running a simulator for both of the secondary o2's.
If I cruise at 55 or use cruise control, I will sometimes get a 1147 and 1167 code.
I passed inspection like this, as you are allowed to have 1 not ready monitor in New Jersey for vehicles newer than 2001. Vehicles between 96 and 01 are allowed 2 not ready monitors.

When you are using an O2 sim with zip tied sensors, using cruise control will sometimes cause it to throw codes for the secondary sensors. I've never seen an explanation of what causes it, though.

Ugh.. It's still here..... Still got a cel light. If I reset it, and drive automatically, It won't come on. As soon as I turn the car off after reseting and driving, 1 mile later, it comes right on... Sparks, I might be paying you a visit man. Code for both secondary o2 sensors..... Not sure what it is. o2 sim is not working.

One of the o2's has a messed up tip, would that trigger both o2's still? I'll run exact codes tomorrow. As for the wiring i'm 99% sure it's correct. I'll post a video tomorrow since pics dont come out clear. Here's another thread I had posted with some decent pics. I'm not sure if you can make anything out. O2 sim is blinking..

The pics show that the o2 sim is blinking and that one of the secondary o2 sensors tip is broken off.

Alright, i'm gonna go out on a limb and assume the sensor is screwed since it's reading high voltage one day and low the next. And i'm hopping that that clears the codes for both o2's..

Nope, but I did get a new o2 sensor that i got for dirt cheap because.. Well. It's a long story. I didn't have these codes but the oem o2 sensor that was on the car before header instal didn't want to come out. So it was cutt and just the harness was connected. I now bought a o2 from a local here that was beat up (in the pic) but for a pretty cheap price. I figured i'd see if that worked. But since that sensor that is beat up is reading high voltage one day and low the next i'm assuming it's fried. Hopefully a replacement one should do the trick I hope. (fingers crossed) autozone has it for 120. And the universal one that needs splicing is 60.. I'm waitin for someone to part it out..
Edit: will a 3.0 o2 sensor from a 01 work on a 02 3.5?

Yes. And a ziptie huh? The first code I was pulling was no activity in both banks. I got the o2 sim and now it's reading high voltage on both. So it's readin that they are plugged in just "high voltage" which i'm assuming means the o2 is gone. If you look at the pics I posted you'll see what I mean.. The tip is gone, it was dragged for a while on the floor while driving before noticing it..

Well ****, I should be denounced to a noob... Wow..... I had both white wires spliced on the same o2 sensor... Moved one to the second o2 sensor and ses is gone.....
Just saved myself 120 on a new o2...... What a relief.......

Anyone know where I can get a oem direct plug in o2 sensor for cheap? Or a decent deal?
Edit: Anyone know if this will fit the bank 1 sensor 2 location?? It's not bosch but any luck? it's 60 bucks...

Both sensors are tucked under my engine cuver, they are NOT plugged into their bungs. Would that throw a code without the 2 (10) ohm resistors? I honestly don't know where to go.. The o2 sim is now 100% wired in correctly.. Both sensors are tucked under engine cover..

I guess you could try a new O2, but that isn't a cheap way to find out one way or another. Maybe try different O2 sims?
When I was getting a bad code for the bank 1 rear O2 heater voltage and replaced it, I immediately got a P0420 code (bank 1 precat) so it might be the sims aren't working right to cover the missing precats.

HEre's a pic of instal. I just got another o2 sim, The crappy o2 sensor itself shouldn't matter since it's readings are cut to allow the o2 sim to function.
The white circled ends that go no where were the ones leading back into the harness(towards the sensor itself). They are spliced into the wires leading back to the ecu.. Anyone see any mistake?
Before I never cut the white heater wires leading from the harness to the ecu. Which is why I was throwing the high voltage code. (I had the sim+ normal heater from harness to ecu) I now cut the white wire on the back of each harness(blue and green) and am just running the o2 sim spliced into the white wire on each leading to the ecu... Reset ecu.. Assumed I'd be codeless now.. And bam... Right back on..

I just spliced it according to puppetmasters. I forgot to cut the white heater wires. I did that and got rid of the 138 and 158- the high voltage codes. Just pulling a p0037 now which is low voltage bank 1 sensor 2? And now I REALLY have no clue where to go?....
Pulling low imput for that sensor.. btw..

Can I do the 10 ohm resistors and completely be sure to knock out these codes?
http://www.radioshack.com/product/in...uctId=2062291#
One o2 is bang'd up, and reading around it seems the o2 sim just sends the voltage needed and not the heater codes. Which btw i'm pretty sure is a bad o2 sensor itself..

ok, so I just checked and saw those are heater circuit codes, so unless you wired something wrong its totally unrelated to the O2 sim installation. You either need a new sensor or the resistors.
