Conditions for Setting the DTC

(Common EVPD Enable Criteria) 

• System voltage is between 10 and 16 V.
• Barometric Pressure (BARO) is greater than 72 kPa (10.4 psi).
• Engine soak time is greater than 720 minutes. Or, at startup IAT - ECT is less than 112 °C (233.6 °F).
• At start up, Engine Coolant Temperature (ECT) and Intake Air Temperature (IAT) are between 0 °C (32 °F) and 40 °C (104 °F).
• Startup IAT - IAT is less than 3 °C (37.4 °F).
• Purge enable time is less than pre-determined value based on startup ECT.
• Fuel level is between 6% and 93%.
• Engine run time is between 1 second and 360 seconds plus purge enable time.

(Small Leak Enable Criteria)
