Repair Verification

The malfunction indicator lamp (MIL) may remain ON after the repair unless the DTCs are cleared.

  1. Seal the EVAP system and use the flow meter on the J 41413-200  calibrated to 0.51 mm (0.020 in) to determine that there is no leak in the EVAP system. See Special Tools .
  2. Clear the DTCs.
