I have read every thread on here, Nasioc, IWSTI forums no one tells if they fixed their issue with this code.


Mods: that i know of,

HKS Hi power exhaust, Catless DP w/Wideband in downstream O2
Injen CAI
TurboXS UTEC


I even change the Rear O2 sensor and cleared the code and it came back on within a 100 miles.

I'm thinking it's a ground issue from the connector leading to the PCM.


Let me know if anyone has fixed this problem

 

what year sti, it may not matter but is still helpful if i find something ill pm u if thats cool.

 

pm me with ur email add and i will send the diag for this code
