I pulled the codes and got TRAC code 47 which states "when idle switch is on, sub-throttle position sensor is 1.45v or higher". The other code I pulled was code 51 which states "Problem in engine control system". Not sure what they mean..

I got the same code (51) and I also have code 47. Not sure yet what they mean exactly.

code 47 is a too much volt in the sub-throttle sensor , adjust it downward
