P0445 Jeep Code - EVAP Purge Solenoid Circuit
Quick Answer
The Evaporative Emission System (EVAP) Canister Purge Volume Control Solenoid Valve controls flow rate of fuel vapor from the EVAP canister. Common causes include Faulty Evaporative Emission (EVAP) Purge Solenoid Control, Evaporative Emission (EVAP) Purge Solenoid Control harness is open or shorted, Evaporative Emission (EVAP) 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.

Code P0445 Jeep Description
The EVAP canister purge volume control solenoid valve uses a ON/OFF duty to control the flow rate of fuel vapor from the EVAP canister. The EVAP canister purge volume control solenoid valve is moved by ON/OFF pulses from the ECM. The longer the ON pulse, the greater the amount of fuel vapor that will flow through the valve.
