Re: Check engine light on
The last two codes you rote have somthing to do with the electronic throttle control. the gas control is no longer controlled by a gas cable but is now all controlled electrical. so this is not a self fixer. must be checked by dealer or someone that knows what thay are doing.

Check coil #3 on v6 and #4 on v8. Usually the coil closet to passenger read side of engine. You probably dont feel a misfire, but put the car in drive and firmly hold brakes down. Rev to about 2k or 3k rmps. If it stutters thats your issue.

Having similar trouble. Started with 12 codes now after replacing fuel pump and vapor management valve I still have 3 codes P2112 P2104 and P0451. Starts right up but idles very rough little response to pedal. I replaced tps and throttle body motor no change. Is it possible I need to have the PCM flashed? Any help or resolve to someone else's problem helps. Thanks!
Replace your gas cap,Disconect your battery for 30 seconds (if you have secure anti-theft system follow instructions for disconecting the battery found in your owners manual.Reconect your battery codes will be cleared.
all the codes point to throttle body. clean throttle body, especially around throttle plate. check for loose wires, if problems persist. replace throttle body. p2104 is tac system forced idle, p2111 is tac system stuck open, p2112 is tac system stuck closed. clean throttle body good, and see if this fixes it. then go from there. have a good day !!
The p2104 code was set because the PCM had to set the idle speed, the p2112 was set to indicate that your throttle body was stuck closed. You can try to remove the throttle body and clean it, check to ensure that it opens smoothly, check the TPS connector to ensure that it is plugged in correctly, reset the light and if the problem returns, you will probably have to install a new throttle body assembly. Hope this helps, let me know
