Trailblazer, Clean Throttle Body, Electronic Throttle Control, Codes P0506 P2119

Trailblazer Clean Throttle Body ,Electronic Throttle Control, P0506 P2119 P0106 P2176.Electronic Throttle Control .On this Chevy Trailblazer I read the codes and cleared them with a Snap on Solus Ultra. A few days later the Chevy Trailblazer was dropped off to get fixed.When the Chevy Trailblazer came back the Solus Ultra showed it had a P0506 and a P2119 code. Both codes and the codes of the first reading can be due to a carboned up drive by wire Throttle Body.I mainly used Throttle Body Cleaner ,but also used a soft rag and soft bristled brush to clean the drive by wire Throttle Body or Electronic Throttle Control..I do not like to open and close the drive by wire throttle bodys by hand and only open just enough to clean.I guess after removing the drive by wire throttle body ,you could hook the wire up and with engine off keyon ,have some one step on gas to open it.This is how I clean Electronic Throttle Controls ,others may use different ways.
