www.deliii.com ... downloads section and get the rsx manual and actually look it up for yourself.. isnt that hard!

 

its primary 02 sensor may be its not connected or its bad

 

does it need to be connected?? i checked under my car today and i seen a connector that was just hanging by the exhaust but was melted coulnt just disable it?? thanks for the replies

 

yes you can but it will throw your car into a default a/f of 10.70:1 and it will run crappy as hell and it is not recommended. believe me i was having the same problem.. see if you can salvage what you got man...

 

u have to connect tht sensor other wise ur car will run rich mang

 

u guys are the best thanx

 

would it matter where i put the o2 sensor at is their a reccomended place?? i have r crew headers.

 

they should already have a spot for the sensor. i know mine did. but i got the dc headers

 

so did ur header come with two holes for both sensors?? do both sensors need to be connected? i have one that is connected and the other well u know?

 

P0134 code is the primary O2-sensor response error code. The ECU somehow checks the response time of the sensor during a certain period of time just after the engine start-up. Getting this code does not mean your lambda is broken. Just disable this code from Parameters - Closed Loop in kmanager-software.

 

if tuned already and then disable does it affect anything?

 

No.

 

im pretty sure it affects ur car. i disabled mine and it ran like shit, bad gas mileage (15 mpg) bogging during normal driving. if you search on club rsx they talk about it. i tried searching for another alternative even after having it tuned (twice). and i am goin to try changing the o2 out for a new one. on a side note i checked my o2 sensor and all wires are intact no melting of any sort.. ???

 

If it affected your car, then there really is a problem with your lambda sensor or wiring. I used to get these error codes in start-up with older kmanager versions and had the box ticked. That didn't have any effect on my tune or the way my car ran. At the moment I know of one car that still has to run with this error code disabled.

 

I havebt disacled it yet and i havent really checked to make sure the 02 is working correctly, as for the melting it was my secondary connector that is a bit chewed up

 

"box ticked" ??

 

Ticking the box from the kmanager to "Disable P0134 (O2 sensor response)" error code from "Parameters - Closed Loop".

 

ooohh

 

im not to familiar w/k pro but i have hooked up my laptop just to see why i had the CEL but as far as my changing settings i could do this right??

 

nothing special needed?

 

so i was checking out club rsx in the ecu tunning section,Hondata K-Pro and reflash FAQ, and this is what i found
How does the K-Pro work with a race header that doesn't have a secondary oxygen sensor?

The K-Pro uses the primary (wideband) oxygen sensor to determine air-fuel ratio and for open/closed loop operation. The secondary sensor simply determines if the cat is there and the primary sensor is working. Without the secondary sensor, the ECU will cause a P0134 error code that can be disabled in the K-Pro Parameters window.

 

No, I didn't have my secondary lambda wired to work (european CTR using PRB ECU) and this did not trigger P0134. In case you don't run secondary lambda sensor, you just need to disable OBD2. I have understood that P0134 has nothing to do with the secondary lambda...

(as I mentioned before, I had the error code with earlier versions of kmanager, not with the newer ones, see here.)

 

Ok, now we had the same problem with another car. Suddenly got P0134 and disabling the error code didn't help. Then we checked the wiring, because we thought the FI setup on the car could have melted some wires. Wires ok. Then we replaced the primary lambda sensor and that fixed the problem!

Kinda weird as we usually get code P1166 when the lambda dies. And they do die often

 

where did u get the sensor from? how much? i fixed my problem by disabling in kpro, but now im getting a p1162 slow o2 response i hear it may be my o2 is dieing

 

Got the sensor from my local Honda dealer ~$185, but won't help you as I'm located in europe.

 

dam thats alot of cheese
