I did the tonering mod on my 03 HO and all was well - no codes. Then, a week later I moved the ring back a little and got codes 0107 and 0073 on the next drive. Something else has been going on before the ring mod because I saw the MIL light flash once one day but didn't stay on. Will someone please look up these codes and post them. Won't codes go away after some keystarts if the problem goes away? TIA! Craig

 

Here's the code's.

are these the same for a 2005

 

The MIL light will reset after 3 "good trips" assuming the problem is gone. A good trip is somewhat defined as getting up to temp but the computer sometimes looks at other variables.

 

Great, thanks guys!! Craig
