P2238 Code What to do? '09 Vibe

[jcsoup]

The engine light and traction control light came on in my '09 Vibe (1.8). The lights were steady and there was no noticeable difference in performance. I cleared the code and drove for several miles and it has not come back on yet. I noticed that my wife had plugged her iPhone charger into the AC plug. Could the current draw from the AC inverter have anything to do with the P2238 code kicking up? What componant should be changed out if the code continues to show up?
