Each second I get 2 error message in console

Question

Every second I see twice an error message:
"21-12-13 16:15:57,000 kernel[0]: SMC::smcReadKeyAction ERROR TC0D kSMCBadArgumentError(0x89) fKeyHashTable=0x0xffffff81bba49000"
I have tried following:
-  creating a new user ..... same error messages (in this case while nothing, except system, was running)
-  reinstalled OSX using Cmd-R at start-up ...... same error mesages.
I do not know whther this rror message means something is not working right but it dos not seems 'normal' that the same error message pops up twice each second.
What to do?

Answer 1

I'm not aware of problems with safe boot. Works fine here, at least. In this case consider using a utility such as Mavericks Cache Cleaner 8.0.3, Cache Out X 6.0, or OnyX 2.8.1 to clear out caches, log files, temp files, etc. in the event the problem is a corrupted file.
If you have no success then reinstall OS X:
Repair the Hard Drive and Permissions - Mavericks, Lion/Mountain Lion
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
Reinstall Mountain Lion or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
     Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is
                three times faster than wireless.
