Ya I searched, i got a ses today

p1147
p1167

I have a daul output 02 sim installed from o2sim.com


What could possibly be wrong? I soliderd all my connections. And the light on the little box blinks.


Thing is I just left the sensors zip tied next to the coilpacks.
What should I do guys.


I also left the front sensor touching the a/c unit, Is that ok?


For some reason my car feels slow as hell... I mean it feels bad...

 

BUMP.


does anyone know if both led's are soposed to blink or just one.

One stays on the hole time, the other blinks.

 

I am experiencing the same two codes with mine now. One LED blinks completely off and the other one blinks more of a high-low, doesn't go completely off. Not sure what is causing it. I was pulling P0138 and P0158 before I got a new O2 sim, and not I have these two code popping. So frustrating!!!

 

check the fuse, my 02 is still ****ed cause the front 02 is hitting the ac compressor, and we soddered *(sp?) all connections, kept blowing the 15amp fuse.

 

Where you getting these codes?

 

Hmm, my sim only has 1 blinking led on it and it blinks if working properly. I would ziptie all o2 sensors and the sim under the engine cover just to be safe. What does those code mean?

 

p1147
p1167

Heated oxygen sensor 2 maximum voltage monitoring. The maximum voltage from the sensor is not reached the specified voltage.

You get what you pay for.

 

Don't get me wrong but did you use o2 sim to simulate rear or front sensors?
O2 Sim dedicated for use only w/rear sensors. According to codes you have the problem now associated with your front 02 sensors.
Last but not least check and make sure that your O2 sim connected to the rear sensors not FRONT!!!

P.S.
Did you remove front O2 sensor?

 

Those are heated oxygen sensor 2 codes, aka rear sensors.

 

Both Epacy and Maxspeed have HS or Cattman headers so they're simulating their secondaries. Maxspeed is just saying his front sensor connected to the header is touching the AC line.

So your saying its a faulty o2 sim correct?

 

Those codes are voltage errors. If the sims were installed properly, wouldn't you say it's a logical conclusion?

 

i was just making sure i wasnt missing anything. No need to get sassy.

So the best solution is to reconnect everything and if still the codes try and get a refund for a faulty o2 sim. I hope i dont run into this down the road.

 

Thanks for clearing it up huff.


here is what the guys from o2sim.com said :

"David,
Those error codes are nort related to o2sensors.
P1147 it is Manufacturer control air fuel metering and
P1167 is the same.
O2sensor related error codes are: P0137,0138,0139,0140,0160,0141,0037 etc,all starts with zero.
One LED should blink,another stays lit.



Which he is right ,cause the odb 2 did say air fuel monitoring.

Im thinking MAF, and that would explain why my car feels slugish sometimes??

 

Although a p1147 and p1167 can be caused by an intake leak, that would only be the case if you had real o2 sensors, but Nissan defines those codes as a rear o2 sensor voltage errors as stated earlier.

humm ture, so
But why did the obd 2 say air full monitoring?

 

I'm not sure, but I think the P1xxx codes are manufacturer defined. For example, a p1147 code on a Hyundai is a throttle position sensor error.

 

Yes, my OBD scanner said "Manufacturer Control Air Fuel Metering" as well.
And codes that do start with a 1xxx are manufacturer specific.
Still don't know what would be causing those codes. Anyone else resolve these codes before?

 

After searching threw alot of threads today, I think its my MAF cause all of this or at least part of it.

It acted funny on me before, cleaned it and it was ok for a few weeks.

Now some times the car is awsome, feel great and fast, sometimes i hit the gas and it seems like im missing a few cylinders, rpms climb slow is the most noticeable thing.

I also noticed the max % air flow on my safc was hitting 74% earlier this week, this morning the highest it got to was 71.4%

 

I thought about the MAF bit as well but, there is a Nissan TSB out there that specifies P1147 and P1167 are related to rear O2 sensors. It seems Nissan deems these codes are for O2 sensors, regradless of the "typical" decsription given out by the code reader.
Additionally, I have the new/upgraded 2003 MAF in my car already, only been in there for 1.5yrs. Also, had the ECU reprogrammed after I put it in.
I started popping these after I took off the intake, IM, and valve cover.
I also read somewhere that a generic reason might be a loose hose clamp or cracked hose, that can cause this reading. Might go through all my connections again. The OEM clips that hold on the vaccum tubes I hear can be worhtless after you open them up once to take them off. I might reaplce the hose clamp on my PCV valve just to be sure.
I had to replace the clamp on my breather hose to the intake before, cause it was the OEM clip and they don't fit too snug after you remove them once.
Just some thoughts.

 

Ya im gona go throught and check my hoses, but whats weird is I didnt touch my Intake manifold since I installed my plugs 2 months ago..And didnt get the codes till I installed the headers and 02 sims....

 

I'm having a hard time understanding how any problem that would trigger a rear o2 sensor maximum voltage error would be any kind of issue when you don't have any rear o2 sensors monitoring your exhaust system.

My understanding of the use of an o2 sensor simulator is to fool the ECM to believing that there are rear o2 sensors that are operating properly and sending signals within specification. Please explain.

 

Well you know something is up w/ ur MAF bc of the low max air flow % from the safc. So would a bad MAF be in any way related w/ the heated o2 sensor codes or is it just a coincidence that those codes popped up around the same time ur MAF went out. And if it is just a coincidence then what caused those codes to pop up in the first place when ur o2 sim is working properly? I cant see how they would be related either. Keep us updated maxspeed.
