Circuit/System Verification

  1. Ignition ON, observe the DTC information with a scan tool. Verify there are no other DTCs set.
  2. Idle the engine at the normal operating temperature. Compare the Desired Idle Speed to the actual Engine Speed with a scan tool. The actual Engine Speed should not be less than 100 RPM of the Desired Idle Speed or 200 RPM greater than the Desired Idle Speed.
  3. Allow the engine to idle within the Conditions for Running the DTC. DTCs P0506 or P0507 should not set.
  4. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
