ok guys i know that this is the O2 sensor codes that there bad but my car has been acting weird like when i crank it up in the mornings it idles at 2k and when it is at normal running tempurature and normal idle RPM at 600k it goes back and fourth between 800k and 600k i took the TB off and cleaned the Idle Air Control and everything... its really beginning to get on my nerves and i really need some help thanks my car is throwing the p1166 and p1167 codes any help would be very appreciated thanks:dontknow:

02-07-2006, 09:11 PM
o yeah fellas i forgot to say that when i take the scan tool and erase the code it comes right back as soon as i crank the car up i know with a o2 it will take at least a couple of cranks to come back on help me out people plz

I had the exact same code on my EP. P1166 and it turned out to be a blown heatercore fuse. This is a 25 fuse in the engine compartment. Its one of the larger ones. Looks like a little green box. What sucks is that this fuse is like 20 bucks from honda. Check this and see if this is your problem also. BTW, when this blew, the only mods I had at the time were I/H/E. I've since replaced the fuse and everything is good.

3 fuses to check first. #14 under hood (30A), and #2 (20A) and #4 (10A) under dash. My bet is #2 is blown, probably a short in the sensor or wiring, you'll know if it blows again.

thanks.. I couldnt remember the fuse exactly. Thats why i described the one that I blew. lol Im willing to bet his problem is one of these fuses.

are all these fuses located under the hood fellas? and how can you tell if the black housed fuses are bad with a ohm meter?

02-08-2006, 10:05 PM
yeah.. they are all under the hood... a multimeter will work... the black ones should be fine... check the green box looking ones. You can see the connection through the top.

Assuming that the ECU is okay, there are only 3 things.
1. The sensor is bad, replace.
2. Wiring problem somewhere.
3. Your A/F sensor relay is bad. It is located left of the ECU under the glove box. Did Acura check it?

Back when I was a noob and I installed my DCRH/Caspers O2 sim I accidentally attatched the primary to the 2ndary with the o2 sim... and fucked things up... blew some fuses and I still have a primary o2 CEL... so I just busted down and bought a new one... and I have a new ECU coming too with reflash... if I dont lose my CEL I will probably snap... goodluck bro..

1badDC5
02-23-2006, 01:01 PM
na acura didnt check the a/f sensor relay could that be possibly what it is i know theres nothing wrong with the wiring and the fuses are good its got to either be that relay or the o2 sensor..one of the two

Stitch
02-28-2006, 09:46 PM
actually... i have a book with the codes in it right here :)

P1166 = Primary HO2S (No. 1) Heater System Electrical (guessing that would be a fuse)
P1167 = Primary HO2S (No. 1) Heater System (guessing that would be the actual sensor)

im confused on where these fuses are :dontknow:

The under hood fuse box is on the driver's side, near the battery. The under dash fuse box is under the steering wheel . Remove the panel under the steering wheel and bend down, you should see it. If needed, the A/F sensor relay is under the glove box, left of the ECU.

you can see it. if you look at the other connector. there should be 4.
i remember when i rewired mine there was a black,grey, and two whites. just connect to each other. but be careful if you connect the wrong wires in the wrong holes you might fry the circuit and blow a fuse.

if you want to wait i can get the wiring diagram and find a way to scan it at school.

xidau
05-08-2006, 12:34 AM
i know there are 4 wires. i figured out the pins earlier today. i know that the 2 blacks go together and the white & green go together. if looking from the back with the clip on the bottom. left is white and right is green. the bottoms are 2 blacks.

i bought it used off here with a guarantee for $100 ... most people would suggest not to do that, but I was strapped for cash and had this guys guarantee it would work or I would be reimbursed. You may want to check www.k20a.org also. But you will be looking at atleast $200 new for it.

maybe p1167 is the secondary o2? not sure

Oh my fucking god you people dont know how to read. Neither of the codes have anything to do with a cat or secondary sensor.

The reason why you are still throwing code 67 after replacing the 02 sensor ws becuase 67 has nothing to do with the o2 sensor it self, it has to do with the wiring. Check the wires for cuts, burns, or melting.

Stitch
12-19-2006, 03:10 PM
maybe when installing your second 02 sensor, you pulled on the wiring for the first one and it may have created a good connection, which coudl explain why you've thrown it more than once.

Hey I got the same codes on my KManager (p1166 and p1167). So I guess I'll be ordering my o2 sensor today, and I seen a fairly priced one here http://www.acuautoparts.com/search/?N=9167+9493+4294967262+1562&Vi=9493+4294967262+1562&y=2003&mk=Acura&md=RSX with free shipping. The SKU# is BS15397 this is for the 02-04 RSX Type S; and for the Base model the SKU# is BS13680 and the prices are the same $199. I'll let you know if this eliminates my problem.

No reason in particular didn't really care which one I get as long as I know it's OEM specification. I just seen that Denso it's a lil cheaper but I bet there is s/h so it'll still be about the same price. Just called up a local autozone and the can get me the Denso for $157 and I get my military discount lol. So I'll get that and see what happens

Ok. Here's my story. Ordered from sparkplugs.com - out of stock, though Denso's are cheaper there. Cancelled order - ordered from oxygensensors.com - $0 shipping total cots about $207. The Denso's are OEM. On the side note, Bosh are probably just as good, it is an oxygensensor and cannot be made to last forever.

You should go to your local autozone store, no shipping and the price is cheaper. Before anyone asks it's the one before the cat and the part # is 234-9005

Having similar ECU codes with P1166 and P1167 on a stock 2002 Acura RSX.

I bought a new A/F sensor from the Acura dealership ($300) and am still pulling the P1166 code 20 seconds after resetting the ECU and starting the car.

I have done all the continuity testing, checked all the fused, checked for loose wired/connections and shorts. I've followed the service manual to a tee... everything pointed to the A/F sensor..

Anyone have any idea why the new A/F sensor didn't fix my problem? Getting very frustrated here.... this has to have happened to somebody else and I know they know the answer!

Have you ever spliced into your ECU wire

Have you ever spliced into your ECU wire

No... why? Were you thinking there is still a short or broken wire? Let's just say I have (even though I haven't) because I have tried everything else I can think of... so what if the wires were spliced into?

I've thought about cutting the check engine light out completely! But I still doubt I could pass emissions with that...

slymmfitzyc
04-11-2008, 01:19 AM
I simply replaced the o2 but you said you did that so you gotta make sure you didn't get the rear sensor instead of the front but if the connector plugged right in chances are it's the right one. Since you say you checked all wires and fuses; put the old one back in turn on the car hook a multimeter on the wire going into the ECU check current and voltage values. You would have to check the manual for exact values being received from the O2, next do it with the new one. if both values match then it's evident there's something wrong inside your ECU. (You can you use the new one first if you prefer to since you know it's a known good o2 sensor). This way is to see if the old one produced a value the ecu couldn't handle and a circuit was burnt inside, but the fuses would eliminate that before the ecu could be harmed. LOL There are so many possibilities man. Just try what I said and tell me what you get as values coming into the ECU

slymmfitzyc
04-17-2008, 08:17 AM
so... how did you fix that problem?

I had a little time on my hands so with the bad sensor you won't get any voltage around .002V and with the good O2 sensor you should see around 1.5V at (750 rpm) idle.

I have the same codes and they popped up after I installed my RBC manifold and race headers still haven't bought a primary sensor to see if that's the issue but I've felt that my car might have like voltage issues or something because everytime I would roll up my windows it would kinda idle.. And now what it does is that it idles from like 1k to 1.7k rpm then after a few seconds maybe 15. It just goes back down and stabalizes.. Any clue on how I could fix this problem?

The only problem that I would see with that is if your problem is the connector itself . . . but personally for $40 versus $200 I would give it a chance.

any reviews on these sensors yet?

my 02 just hit 105k miles, and im getting these exact codes.

bought a replacement primary o2 sensor from the clubrsx store. Im hoping that fixes it

Yeah i too have the code P1167 but not the other. im guessing its the wiring or so. Which 02 sensor should i look at? the one that's connected to the header or the cat?

Yes. You should need a new one with that many miles anyway.

I got both codes and have been driving around for a year now with the engine light on. I will be heading in for an emission test so I went ahead and bought the Denso Primary o2 sensor right hear on club rsx for $200 and it fixed the problem (the part arrived in only 3 days). I had already replaced the cat once before with a Magnaflow and the sensor was on it so tight that I had to break off the top of it to unscrew the bolt. The sensor removal tool was not going to do it and that was only after I removed the entire exhaust from manifold down to the muffler section.

I have had P1166 for over a year now aswell and have replaced the primary sensor twice and chexked all fuses and relays and still cannot get it to go away. Seriously think its either my kpro harness or the secondary 02 that's causing the primary to trip. Now I know that some of you will say that the secondary has nothing to do with the primary, but I have replaced everything else and have done all of the trouble shooting steps and have cleared my drc's in k pro and it still stays there. It has gone of for like a half a day on its own once like 4 months ago but that is it.

the way i fixed my is, by puttin a $2 clock in front of the check engine light..

I unplugged the secondary sensor to see what kind of reading I would get and it gave me a third error code along with 1166 and 1167. When I plugged it back in it went away. Since you are saying that it sometimes goes away and the code is for a faulty o2 sensor it could be a bad connection. I do not know which sensor you got but the Denso is oem.

Yeah I got a denso twice. I guess I'm gonna buy a new secondary and see what happens. It has only went away and came back once. Its not likme a repeated thing

My car failed inspection and these codes 1166 and 1167 came up. Is it worthwhile first trying to replace the fuses mentioned earlier?

I looked under the dash and did not see a "#2" fuse.

I have an RSX 2002 auto, with only 50K miles. Seems early for the A/F ratio sensor or sensors to go bad, doesn't it?

Sock 2002 base.

I got both p1166 and p1167 codes. I cleared the codes turned the car on and 3ish seconds later the check engine light came on.

Checked the fuses they all seemed fine.

Called around to get prices. Parts Source wanted $246 (CDN) for a NGK O2, Canadian Tire wanted $261 (CDN) also for a NGK O2, and the Honda Dealer ship wanted $286 (CDN).

I bought the Honda O2 sensor. Came in a red Honda box. The Sensor it self had DENSO written on it by the threads. There is a little cap that covered the threads and the threads already had anti seize gunk on them.

I am not a mechanic. I have never worked in a garage or taken auto shop classes. The hardest part I had was unhooking the electrical connection. I thought that the female end of the connection was attached to the little metal bracket that is holding the "connection". So I was trying to push in both "tabs" and pull at the same time. I could not get the metal side to budge, but I was able to pull the male connection one way pressing in the tabs to get the connection to come lose still having the metal part firmly in place. Now I didn't have to worry about pressing both tabs in and pulling I just had to worry about pressing the metal side tab in and pulling. I grabbed some vice grips put the vice grips on the male end used a flat screw to push in the tab that on the metal side. I was afraid to pull too hard because I thought that the female end was attached to the metal bracket and the tab on the male connection was attached to both the female connection and metal bracket. I got pretty frustrated fighting with this electrical connection I kept running back to my work bench to examine the new O2 sensor and how the male connection worked. Eventually I ditched the vice grips grabed the O2 sensor wire and pushed in the tab with a flat screw driver pulling hard on the wire then a little hard then a little harder and it popped off.

Now I got a good look at how these connections worked. The female part is not connected to any bracket. The one tab away from the metal bracket is the only thing holding the two connections together. If I were to do it again it would use a flat screw driver to push up on the female connection pressing in the non bracket side tab to pop the connection off and then worry about disconnecting the male end from the metal bracket.

I would also use some PB Blaster or something to spray on the metal bracket since I think alot if the issue was due to the metal bracket being rusted and corroded (Canadian Eh so the snow and salt under the car had a role to play). I had to use some muscle to get the connection back on to the metal bracket as well.



I know this is a long write up but the whole thing took me 40 mins. It would have been 10 if I didn't have to fight with the electrical connection.


After the new O2 sensor was installed I fired up the car and the CEL light was still on. I grabbed the OBD2 reader cleared the codes and they did not come back.

I was blowing the p1167 and then I changed the main 02 sensor it fixed it I'm about 40 miles driving and there is no check engine light so far so good!

Ive got that code too, i bought the car with it and when i bought it the guy told me that came right after he installed DCRH on the car. I asked him if he used a defouler and he said no so i figured it was that.

Yesterday I installed a DIY spark plug defouler and reset the CEl, it came right back. I pulled the code and its #41, p1166 p1167.

Ive been doing a lot of research and it sounds like that is either my primary O2 or the wiring, I have checked all 3 fuses and they were good, but i replaced a couple with new ones anyway.

What I dont understand is how i wasn't throwing a code for no cat, to begin with. And does this code refer to a dead primary, having nothing to do with the secondary??

EDIT: Its an 02 type S with 112k miles. CAI/RBC/DCRH/E

It's used but guarantee it works it is a primary sensor.

Question...

I bought a new primary o2 sensor because I was getting p0134 code and my car was getting terrible gas mileage plus running like crap. When I tried to remove the clip on the old one it wouldn't budge. I must have gone at it for over an hour when I said fuck it and decided to splice my new one onto the old clip. I spread out the solders as to prevent a short and wrapped it nicely in electrical tape. Now my car seems to be running normal again(not sure about the gas mileage, I haven't filled it up yet) but I smell an electrical burning smell. I suspect the electrical tape is getting too hot. What should I wrap the splice with??

Leave the electrical tape on the wires and wrap it with some sort of aluminum tape or heat resistant tape on top of the electrical tape.

3 fuses to check first. #14 under hood (30A), and #2 (20A) and #4 (10A) under dash. My bet is #2 is blown, probably a short in the sensor or wiring, you'll know if it blows again.

13 years later and this helped me today. This is why forums are needed and FB groups are shit.

Same ^ ended up wasting so much money on O2 sensors and I'm pretty sure the 8 dollar relay was the fix for me
