I just got the damn thing running and it came out better than my first attempt, Thank GOD. Car fires up with no issues except that it idles low and a little rough. The CEL kicked on and I pulled a 55 code, from researching it looks like my rear Knock sensor.

How would I check continuity on this? And what should it measure? I extended the wire harness and used sheilded USB wire on both KS. I dont think the wiring can be a culprit cause its only throwing a 55 code.

Can I use a 2JZGE KS or are they completely different?

 

Was the USB's wire gauge smaller than the knock sensor wire?

 

It is but by not much. Question about the USB wire, when people say they are using USB wire its computer USB wire?

I really dont think its the gauge wire size cause I extended the front one as well and its not throwing a code for that knock sensor.
