i finished wiring up my solenoids the other day, i used the brown wire from the throttle body that read 4.9v at wot. but when i have the system armed the solenoid opens up at 45% throttle (i hooked it up to a scantool) and the pedal is only about halfway depressed. ive made the purple box relearn my tps signal multiple times and it still opens up at about half throttle. my question is to anyone with a zex kit does this happen to you or does yours open at wot?

i figure either way ill run the car like this because ill only have the system armed when im about to spay anyways, but i just wanted to see if anyone else is experiencing this.. thanks

 

ummm dont you want to find the one that has failing voltage??? so the voltage drops when its at wot? what is the wire reading at no throttle?

 

it reads 0v at no throttle and 4.9v at wot, ive always heard people say to use the brown wire and the directions say to use the output lead from the tps, meaning the wire with the highest voltage at wot... at least thats the way i understand it. anyways the brown wire had the highest voltage at wot.

 

hmmmmmm i always thought you wanted the one with failing voltage is there one with failing voltage?????

 

whats failing voltage?

 

bump.. no one else has experienced this?

 

well first off that is the motor wire, not the throttle postion sensor. the throttle postion sensor is the light green wire. i have this same kit on my tc and the white wire goes to the light green wire

 

i tested the green wire too and that only saw about 3v at wot, so i went with the brown one.. either way it works, i dont have it armed when im driving around town, just when im about to use it, thanks for the info though
