DTC Confirmation Test

  1. Turn ignition off, connect scan tool and turn ignition on. Clear DTCs. See CLEARING DIAGNOSTIC TROUBLE CODES  under SELF-DIAGNOSTIC SYSTEM. Ensure fuel tank is 1/4-3/4 full, vehicle is at an altitude of 8000 feet or below, barometric pressure is 75 kPa or more, ambient temperature is 14°F (-10°C) or more, intake air temperature is 158°F (70°C) or less, and engine coolant temperature 158-230°F (70-110°C). Drive vehicle at speeds of about 30-40 MPH under all driving conditions (stop and go, high and low load, or rapid acceleration and deceleration) for 20 minutes. Go to next step.
  2. Drive vehicle at speed of about 30-40 MPH with throttle steady for 3 more minutes. Stop vehicle. With ignition on, check for DTC P0440 and P0455. See RETRIEVING DIAGNOSTIC TROUBLE CODES  under SELF-DIAGNOSTIC SYSTEM. Go to next step.
  3. If DTCs are not set, using scan tool, check completion status of EVAP system monitoring test in READINESS TESTS mode. If testing has not been completed, repeat DTC CONFIRMATION TEST . If testing has been completed, recheck for DTC P0440 and P0455. See RETRIEVING DIAGNOSTIC TROUBLE CODES  under SELF-DIAGNOSTIC SYSTEM.
