After doing my b16a crx swap, i had a code 7, car ran fine. Then the car didnt seem to be running all that great... I did the timing, it was way off, but i didnt jump the service connector?? Does that matter, would i have different results without doing that??
So now the timing is good, but its still not running to great. It started backfiring when i reached high revs, more so than it use to. It always did a little because there is a gutted cat, straight pipe, and a fartcan , thanks to the previous owner. I cant afford to deal with that yet.
I also just realized i started putting 87 octane in it, didnt think it would matter. So today i tried to put the ecu cover back on (and couldnt get it on ... ....WTF ) AND I REALIZED i have a code 23 now.... I had a broken knock sensor, so i never wired it up... Now why do u think that the code 23 appeared somewhere in the last month, but not immediatly after the swap?? I am guessing it started in the past couple weeks when my car didnt seem to run too strong..... Maybe the same time i started putting 87 in it?? I dont understand why it would matter, seeing the knock sensor is not wired.....
Would getting the CEL 23 change my cars performance, ie. timing wise? or adjust the map sensors or anything??

Thanks for any info

 

Knock Sensor will throw the computer into safe mode. Thus retarding the timing, running rich, and no extra services such as VTEC, and such.

Get it wired up or replace the thing

good luck.

 

Yes, more than you might think. If the sensor is broke, replace it and wire it up. Make sure to use shielded wire also to neutralize any surrounding interference's from other electrical parts. Not doing this will also trip the knock sensor more easily.

 

I have a new knock sensor, just cant put it in..... Seems near impossible without ganking the motor...


I have vtec, so thats why i am like wtf?

 

Just filled up on 93 tonight, car is still running really rough?? I have talked to other ppl without their knock sensor's wired and they said their car runs fine......
