Is the trac code only triggered by the engine code? If I fix the engine code, will the TRAC code go away?

25 - Air-fuel ratio lean malfunction


and


51 - Problem in engine control system



I'd just like to know if these are related. Thx

 

i have the same code popping up with my ls....
25 - air fuel ratio lean malfunction
did u manage to fix it if so need tips please.....

 

Not yet no, I still need to change the second main O2 sensor.

I hope it clears up after!
