P0459 Jeep Code - Evaporative Emission Purge Solenoid Control Circuit High Voltage
Quick Answer
The Evaporative Emission System (EVAP) canister purge volume control solenoid valve uses an ON/OFF duty to control the flow rate of fuel vapor from the EVAP canister. Common causes include Faulty Evaporative Emission (EVAP) Purge Solenoid Control, Evaporative Emission Purge Solenoid Control harness is open or shorted, Evaporative Emission Purge Solenoid Control circuit poor electrical connection. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.
