cel code 1= Oxygen Sensor "A" (Primary) defective circuit or unplugged / defective sensor

cel code 7= TP Sensor (Throttle Position) defective circuit or unplugged / defective sensor

would these codes prevent vtec to kick in?

ever since i fnished my swap about 2 weeks ago i have never had vtec...and these are the only codes my motor is throwing.

ive searched and tried troubleshooting y its not kicking in...but still no luck.

97 jdm itr swap in a 96 ek with EX harness

 

bump!

 

bump for some answers man!

 

umm code #1 will, at least it did on my y8 and i didnt relaize for a month not sure about 7

 

bump for some more answersssssssssssss

 

yes, code 1 and code 7 will definately prevent VTEC from PUNCHING (not kicking) in.

 

in that case... will any b series TPS work?

 

from my experience, any TPS sensor has worked. but i only tried ones from the same OBD.
