Most of the 10xx and 11xx codes are momentary drops in communication among the various computers in the car. If these show up as history codes, you can just ignore/clear them. If they show up as current, then there's likely a signal/wiring problem somewhere.

These codes are considered normal most of the time. Sometimes the car is busy doing something, and one or another of the modules decides to say 'hello' to the computer ... which is busy ... so it blows it off. Comm error. No problem.

In general, don't worry about history codes. They will clear themselves after 40-50 ignition cycles, unless you do it first. Only if a code keeps recurring, or shows up as current, should you get concerned.
