[QUOTE="JaysonMFK, post: 12340534, member: 124041"] That's a code for the electronic throttle control. More specifically the "throttle actuator airflow trim at maximum limit" code. Drive by wire can be a pain in the *** sometimes. Especially when it comes to tuning. It's not due to a dirty TB, that situation applied more so when intake air control valves were used.. Your car uses an electronic throttle control system which uses only the throttle body which can supply way more than enough air. So again carbon build up or dirt is not the issue. If you can be a bit more specific on what was taking place when the wrench popped up I may be able to help you diagnosis it a bit better. Was the tune done for the throttle body you currently have on the car? Were you flooring it when it tripped? Was the engine hot and on a hot day? My guess is a lot of tuners adjust the throttle response to give the car a more aggressive feel, which at times causes the ETC to become a bit screwy. I really think you just need an adjusted tune, with a bit less aggressive TPS-demand setting or small increase in the torque tables. It's not something I think you should be overly-concerned with though, just more of an annoyance when it occurs. Call your tuner and see what they say, also update this and let us know how it turned out. I came from the import tuning scene so I'm still getting caught up with what's going on here in the domestic market, so take my advice with a grain of salt lol. I'm not a professional tuner or expert by any means, shade tree at best lol Hopefully that sheds a little light on what's going on though. [/QUOTE]
