I have a 91 civic HB, with a JDM b16a swap, with a pr3 ecu and i am getting a CEL for the knock sensor, so is having a CEL for the knock sensor hurting the performance of my car?

 

up

 

whenever ur cel comes on ur ECU switches over to limp mode...which i believe retards the **** out of ur timing.that alone will make u lose performance..not sure what else it does so ill let others with more knowledge to chime in...

 

It keeps vtec from working too.

 

my Vtec works fine.

 

do you think since my rex is throwing a freaking code 9 that it is in limp mode because it feels strong and vtec is working (obd1 swapped mini-me).....just curios thanx

code 9 is a cyp sensor...it is in the dizzy and i do not think they make a replacement piece for it...get a new dizzy..reset ur ecu and u should be runnin good

...not true to say the least.

Knock sensor cel retards ignition 2 degrees. From what I understand honda knock boards are pretty shitty at there job. Get your pr3 chipped and run a map with the KS disabled.

 

ok, i think i may have found the problem, i am aslo throwing a code for the IACV, so today i went to remove it to clean it and when i pulled the plug it was labeled knock, i had my harness made by rywire, the plug only had one wire running into it, a blue wire. So i figure that if i am throwing codes for a knock sensor and the IACV, and the plug for the IACV is labeled knock, that has to be my problem. I emailed ryan at rywire to see what i did wrong.
