I have just bought this 2003 1500 HD Silverado with 123,000 miles on it. It has went into reduced power mode and thrown this code 3 times since I bought it. I have cleaned the electrical connectors on the throttle body and the TAC module with electrical cleaner and put die-electric silicon grease on them before connecting them back together. I have driven about 800 - 1000 miles in several trips since doing this and it has worked perfectly. Do you think I have solved my problem or is it going to do it again when I least need it to? Any speculation will be greatly appreciated. The truck has the 6.0 and 4.10 gears.
