Circuit/System Verification

IMPORTANT: The engine must first be running for greater than 60 seconds, then idle at a steady state for an additional 10 seconds before comparing the actual and desired engine idle speed parameters.
  1. Using a scan tool compare the desired engine idle speed to the actual engine idle speed.
    • Actual engine idle speed should be no greater than 100 RPM below desired.
    • Actual engine idle speed should be no greater than 200 RPM above desired.
  2. Verify that there are no other DTCs set.
  3. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
