NOTE:
- The IAT PID must be within -6.7 - 37.6 °C {20 - 100 °F} to initiate the EVAP system monitor.
- The FLI PID must be within 15 - 85 % to initiate the EVAP system monitor.
- The drive mode conditions (shown in the table) must be met within 4 to 10 minutes after starting the engine.If the time exceeds 10 minutes, turn the ignition key "OFF" to reset the timer then restart engine.
- After the monitoring conditions are set, system testing requires at least 30 seconds to complete.
- Fuel tank pressure will change as follows during monitoring.

1. Cold soak the vehicle for at least 8 hours.

NOTE: The cold soak period can be shorten up to 3 hours depending on vehicle conditions when the 8-hour-timer bypass procedure is performed. If you shorten the soak period, the PCM may detect malfunction by mistake even though the EVAP system has been repaired correctly. This misdiagnosis will happen more often under warm or hot ambient temperature. If you are not sure whether the system still have malfunction, soak 8 hours and perform the drive mode again. If malfunction is not detected, the repair is completed.
