The idle speed concern can be intermittent and DTCs P2111/P2112 may or may not be present.

1. Determine the engine build date. If the engine build date is within the range indicated here, proceed to Step 2.

  • 0L…2/11/2010 - 8/2/2010
  • 5L and 3.7L…3/1/2010 – 8/3/2010
  • 6L 2V…….5/7/2010 – 8/2/2010

  • DTC O2111 and/or P2112
  • Idle speed lower than desired
