The fault code PE would be stored in your vehicle when the powertrain control module would detect a discrepancy in the evaporative emissions system leak detection reference orifice. In this condition there would be a low flow condition. The design of the EVAP system is made in such a way it can capture fuel vapours before they start escaping into the temperature. A vented reservoir which is also known as canister can be utilized by the EVAP system to store excessive vapours until the engine is being operated under the appropriate conditions so that they can be burned effectively and efficiently. A negative pressure is created by the electric vacuum pump in the EVAP system after the ignition switch has been turned off for 5 hours.
