The numbers below refer to the step numbers in the diagnostic table.

  1. 1:  The Diagnostic System Check - Vehicle prompts the technician to complete some basic checks and store the Freeze Frame data on the scan tool, if applicable. This creates an electronic copy of the data taken when the fault occurred. The information is then stored in the scan tool for later reference.
  2. 2:  This step prompts the technician to check for any condition that can allow air to enter the engine. Any condition that can affect the idle speed of the engine must be repaired first, in order to enable proper diagnosis of the DTC P2282.
  3. 3:  A dirty throttle valve can affect the airflow through the throttle body and into the engine. Clean the throttle valve is necessary before performing the Idle Learn Procedure.
