Re: '03 LS V8 Throttle Body Nightmare HELP!!

You actually only have 6 codes since P0223 and P2106 are repeated in your list.

All six of the codes are related to the electronic throttle body. There are a few other issues that can cause throttle body codes due to electrical noise such as water leaks at the base of the windshield and coil on plug (COP) misfires if I recall correctly. It's been quite awhile since I've read about those so I'll leave that as an exercise for you to search this forum for that detail.

If none of that pans out, you might actually have an issue with the electronic throttle. Here's what the diagnostic codes are defined as:

P0223 - Throttle Position 2 (TP2) sensor circuit high input
P2106 - Throttle actuator control system - forced limited power
P0123 - Throttle Position 1 (TP1) sensor circuit high input
P2100 - Throttle actuator control motor circuit open
P2107 - Throttle actuator control motor processor
P2110 - Throttle actuator control system - Forced limited RPM (this code is likely triggered by the P2100 and/or P2107)
