I recently installed a Power Commander III on my 08 Ultra Classic. Seemed to run well for a while, then I go some backfires and a stall. I pulled it off and it seems to be OK. I did have a historical error code P0120 - TPS1 Range Error. Can anyone translate that into English for me?

Thanks!!!

 

This is what it means....looks like a throttle by wire problem. If you clear the code do you still get it with the PC removed?

DTC: P0120
FAULT CONDITION: Throttle position sensor 1 range error
PRIORITY ORDER: 38
SOLUTION: 6.6 DTC P0120,P0122,P0123,P0220,P0222,P0223

 

Thanks for the information. I just cleared it and will test it out today. Thanks again.'
