Circuit/System Verification

  1. Engine idling at the normal operating temperature.
  2. Verify that no other DTCs are set.
  3. Observe the scan tool Cylinder 1-6 Current Misfire Counter parameters. The Current Misfire Counters should not be incrementing.
  4. Engine idling, perform the Cylinder Power Balance test with a scan tool to isolate the misfiring cylinder. The engine speed should change when each injector is disabled.
  5. 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.
