ok before u tell me to search.. let me explain.
i know CEL 17 is VSS, dont under stand why that comes on, it comes and goes, so i reall dont know what the poblem is with that.
and CEL 41 is o2 heater code.
my brother and i recentley did a d16z6 into a vx swap (prepping for Turbo-D) and that is the only 2 codes that we have, now we have done the 5 wire swap for the o2... why would this code pop up?

 

vss is for vehicle speed sensor... which is magnetically controlled... so it might be working one day and not the other... change that or it could be in the wiring if comes and goes... just check it make sure

o2 heater code... same possiblities... bad o2 ... or not wired right... might be the ecu... never know .. just gotta check ****...

 

hmmm, i just put the p28 ecu in, after i bought it from a friend. so couldnt be that..

 

hmm... id go thru and check wiring... if you have a volt meter check to make sure all thats getting and sending out the right vlotage now o2's make there own power... and it you got a manual it should tell you how much the varation should be it should be somewhere aroun .3 volts to .7 volts... now the vss i dont know and i dont have my manual its at work...

 

ok ill check, one more question, wahts the rev limit and when does vtec engage in a d16z6?

 

dah... ummm i think a d16z6 sohc should rev to 7200 if im thinking right... and vtec should engage around 4,500 to 5000 not sure exactly when...
