06 GXP No Cruise Control

I have no Cruise control, started randomly then all together stoped working, now on a rare occasion, I cant remember last time, it will work.
When it doesn't work:
-the hud goes into the speed set/cruise set screen for maybe half a second then goes back to normal with no cruise control.
-if im not touching the gas when I hit cruise it will rev about 500 rpm then back down.

Things I have Changed recently:
-Led Reverse/license plate/interior Lights (has worked since)-
Played with Diablosport on diff. tunes (makes no diff.)

Codes I throw:
Current - Low Oil pressure/opsu range not optimal or w.e (opsu is broke, don't worry I have oil pressure)

Past - Throttle position actuater range/performance;
^this is what I think caused it, I only seen the code once and it was around the time the cruise stopped working, but I cleared it and it never came back, kind of like my cruise never came back

Hopefully my ls2 throttle body will fix this in the near future
also mods are in sig
Thankyou in advance
 


turn off traction control then turn on your cruise control, Also fix your OPSU- get a new sensor and pluck the OPSU filter out to clean it and re-install.
 
The diablosport tune for the GXP makes the cruise control act goofy, as stated you will need to turn off trac control for it to work. You can leave the stabilitrac on.
 
sorry for the late response i havent had internet for a few days, but it works great TC off, i guess i just never noticed that was when it worked
